Are you starting to believe that your air conditioner is too big? If that is the case, it is likely that you will experience at least one of the following three problems if your air conditioner is too large for your home:
In this article, we’ll go over each of these issues in greater depth, as well as discuss how to resolve them. Problem#1 : Your energy bills are increasing.The fact is, an oversized air conditioner will frequently cool your home extremely quickly before shutting down. Not only does this cause wear and tear on your air conditioning components (because of the constant on and off cycling), but it also has the potential to raise your energy bills. Your air conditioner is equipped with several motors that drive various components (like the compressor and blower). Furthermore, all of these motors consume more power when they are first turned on than they do when they are running. As a result, if your air conditioner cycles on and off frequently, the motors in your air conditioner are drawing more power than they should, increasing your energy bills. In other words, if you’ve noticed a steady increase in your energy bills, it’s possible that your air conditioner is too big. Problem #2: Your air conditioning turns on and off immediately.Is your air conditioning system capable of cooling your home in 10 minutes or less on a hot afternoon? If this is the case, it is possible that you have an oversized air conditioner. Because an oversized air conditioner is too powerful for your home, it will quickly cool your home before shutting down, raising your energy bills and wearing out your air conditioner (from all the starts and stops). Problem#3: Your air conditioner isn’t effectively removing humidity.One of the critical functions of your air conditioning system is to remove humidity from the air in your home, which is particularly important during the hot summers in South East Houston and Harris County. The evaporator coil (which is located in the indoor air handler) is responsible for removing moisture from warm, moist air. The moisture is then expelled from your home through the condensate drain. Indoor humidity levels of 30–50 percent should be achieved with a properly sized air conditioner. However, in order to dehumidify the air in your home, your air conditioner must run on normal-length cycles. As we discussed previously, an oversized air conditioner will cycle on and off on a regular basis. Furthermore, if your air conditioner is constantly shutting down, it will not be able to run long enough to remove moisture from the warm air in your home. As a result, if your home is extremely humid, it is possible that your air conditioner is oversized. How did you end up with an oversized air conditioner?So, to cut a long story short, it’s most likely because the technician who installed your air conditioner didn’t perform a “cooling load calculation.” A cooling load calculation takes into account a variety of variables, including:
An Air Check Mechanical Service technician can only provide an accurate recommendation for the appropriate AC size for your home if he or she considers all of the factors listed above. Unfortunately, many HVAC technicians either do not know how to perform a cooling load calculation or simply do not perform one when installing a new air conditioner. Why would a technician choose to forego performing a cooling load calculation?Consider this: your old air conditioner weighs 3 tons. You might be under the impression that you should simply replace the 3-ton air conditioner with a new 3-ton system. For example, what happens when your old 3-ton unit was already too large for your house? Essentially, you’re just replacing one oversized unit with another oversized unit, which means you’ll be dealing with the same problems as before.

Air Conditioning Maintenance Checklist: Know It!Summer is here in Southeast Houston, friends, and we all know that the heat and humidity of Houston and Harris County are nothing to scoff at. If you’re looking to have a comfortable summer this year, A/C maintenance should be considered and completed as soon as possible in order to ensure a comfortable start to the season and consistent quality cooling throughout. No one wants to be stuck with a broken air conditioning system in the middle of summer heat! Please take a closer look at the Air Check Mechanical Service A/C maintenance checklist provided below to determine what you should be considering this hot summer season. AC Maintenance Checklist1. Check out your condenser and compressor on the outside of the buildingWhen debris, such as leaves and/or dirt, enters the exterior of your air conditioning unit, it is imperative that the obstructions are removed in order for your system to operate efficiently and effectively. Working around a fan blade can be extremely dangerous, so make sure the exterior of your unit and the circuit breaker switch for the unit are both turned off before you begin. Another important aspect of maintenance is to clean the area around the unit and leave at least two feet of clearance to ensure that there are no potential obstacles in the immediate vicinity. 2. Ventilation ductsBecause air ducts are tucked away from sight, they are frequently the most overlooked component of your air conditioning system, and they are the most susceptible to blockages. It is necessary to inspect air ducts for damage caused by condensation or corrosion in order to avoid the need for costly repairs in the future. This can be done by an enthusiastic amateur, but is better completed by a well trained HVAC technician such as those at Air Check Mechanical Service. 3. Replacement of the air filterWhen was the last time you had your air filter changed in your home? If it has been a while since you have checked your air conditioning 4. Coils for the EvaporatorWhen inspecting the interior air handler, make sure that the coil is free of debris and that it has been cleaned with the appropriate tools to remove any ground in dirt. You’ll want to use a soft brush as well as a coil cleaner that is designed specifically for coils rather than an all-purpose cleaner. Believe us, it does make a major difference. In addition to the drain pan, which will require a thorough cleaning to remove the bacteria buildup that has accumulated since the last time the drain pan was cleaned, the runoff from this cleaning will also collect in the drain pipe. Ensure you drain that as well! 5. Tubes for RefrigerantFinally, small metal tubes run from the exterior unit to the air handling unit, carrying the refrigerant that allows the system to regulate the temperature in your home. A professional should inspect these to ensure there are no leaks and to prevent the need for costly repairs in the future. Certainly, inspecting these is something a novice can do, but it is important to recognize that an air conditioner that blows hot air or is not cooling properly may in fact have a refrigerant leak already. Make sure you’re ready to call for HVAC repair if you have any of these issues. Because there are so many variables that influence the performance and strength of your home’s cooling system, it is critical to understand that regular air conditioning maintenance is necessary for your comfort. We hope that by reading this, you have gained some new knowledge and have been inspired to begin your own home maintenance. Call us at Air Check Mechanical Service today to schedule a semi annual maintenance check. via Air Check Mechanical Service - https://www.aircheckms.com/ac-maintenance-services/air-conditioning-maintenance-checklist/ What Kind Of Air Conditioning Installation Is Best For Your Home?Each home’s cooling requirements are unique, and factors such as size, age, insulation, and windows are just a few of the many considerations that can influence your cooling and comfort requirements. These are all considerations that must be made when replacing or installing an air conditioning system, whether you want to cool your entire home or just specific parts of your house or condominium. It is critical to select a system that is appropriate for your needs as well as the needs of your home. It is possible to install a heating and cooling system that is either too small or too large for your space, which will not provide the optimal level of comfort and may result in mechanical issues and costly repairs. Air Conditioning System OperationDespite the fact that air conditioning systems come in a variety of shapes and sizes, they all operate on the same principle: they remove heat and humidity from your home and replace it with cooled air with the use of refrigerant. This is accomplished through the cooperation of three mechanical components:
The Differences, Benefits And Drawbacks Of The Various Types of Air Conditioning SystemsCentral Air ConditioningThe most common type of air conditioning system is referred to as “central air.” It has the ability to keep an entire house cool and comfortable, and because it is nearly invisible and whisper-quiet, you mostly won’t even notice when it is operating. Furthermore, a central cooling system is both energy-efficient and will increase the value of a home’s overall value. With a central air conditioning system, air is distributed throughout the house through one or more fans and a network of ducts. Outside units contain the compressor and condenser coil, which are connected to an indoor unit that contains the evaporator coil. The thermostat, which is usually mounted on the wall, is in charge of controlling the temperature. Central air conditioning is a great option if you have a larger home with existing ductwork or if your home can accommodate new ductwork. Mini Splits with No DuctworkA ductless mini split system is an excellent choice if you want to add cooling to “bonus” rooms such as an office or a sunroom, as well as other spaces such as an attic or a garage or basement. They can also work when you do not have existing ducting that can be used. You can save money and energy by using this method for cooling a smaller home. Mini splits, like central air conditioning, require an outdoor condenser unit. The evaporator, on the other hand, is housed in separate wall-mounted units (also called air handlers). This allows for temperature control that is zoned from room to room, allowing everyone in your household to set the temperature to their personal preference. Furthermore, ductless mini split systems can make it easier to breathe because of their extremely efficient filtration, which can significantly reduce the amount of dust, bacteria, pollens, and other particulates present in the air. Final point is that they can be installed as either a single zone unit or as a multi zone solution, and they are extremely energy efficient when in operation. Overall, a ductless mini split system is difficult to beat for its versatility, convenience, and high-quality performance. AC with High Velocity CoolingDo you live in an older or historic home with no existing ductwork that has radiant heat and requires an air conditioning system that will not compromise the architectural integrity of your home? High-velocity central air conditioning may be the answer to your problems. With this type of system, the air is moved from an outdoor compressor to a single concealed unit (the air handler), which pushes the air at a high velocity to multiple vents throughout the house. Because the tubing is only a tenth the size of a traditional system, it is simple to feed it through walls and around obstacles such as beams and joint joints. Because a high velocity air conditioning system does not require any renovation, installation is simple and quick, and you will not have to worry about your home’s unique character details being disrupted. High velocity air conditioning replaces those noisy and inconvenient window units with the modern comfort and convenience of high velocity air conditioning.

Of course, it’s all pandemic related, even now as America struggles to come out the other side From automobiles to refrigerators, your selection is limited in a lot of cases, and delivery times are significantly longer than most of us can recall. The supply chain for HVAC equipment is exactly the same. Here’s a quick rundown of what’s going on and what you can do to avoid having to pay for a costly HVAC repair or AC replacement while supplies are running low. What is causing the increase in HVAC prices? What is the cause of the HVAC equipment shortage?Manufacturers of HVAC systems, like most companies, are also experiencing supply chain issues, and they are unable to produce the number of units required to keep up with demand from consumers. The fact that raw materials required for production are not readily available is the primary source of this constraint. Suppliers of raw copper and steel, which account for the vast majority of components within HVAC systems, are not operating at full capacity, and what they can produce is not being shipped as quickly as it should be. Labor and shipping costs are rising for manufacturers who are still producing new HVAC units, which is bad news for them. Most major suppliers have attempted to keep costs as low as possible, but they have recently raised prices by between 4 percent and 10 percent. It is possible that both expert AC installation companies like Air Check and the homeowner will face higher prices as a result of this. Unfortunately, it is likely that these higher prices will continue for the foreseeable future, certainly something that has only been exacerbated by war and increased oil and gasoline prices. Aside from being in short supply and in high demand, the computer chips that control all modern, energy-efficient HVAC systems are also in short supply. Additionally, repair parts are frequently affected by the same issues that affect complete systems as well. Parts for older units are becoming increasingly difficult to come by as manufacturers shift their attention to producing new units in order to make the most of their limited production capacity. Will there be a decrease in HVAC prices in 2022?While supply chains and manufacturers attempt to return to normal production levels, it will be some time before we see critical supply chain components return to their pre-crisis levels of performance. Couple that with most corporations using “inflation” as an excuse to hike prices (and profits), and it is likely that prices will never come back. However, if the road to recovery proceeds as planned, it is hoped that supplies of new units and parts will eventually return to normal levels. What you can do right now to avoid having to pay more for a new HVAC system installation?The most important thing you can do is to keep your current system running well. Regular HVAC maintenance, as well as addressing issues as soon as they arise, will reduce the likelihood of having to purchase a new unit during these tough times. A few dollars spent to avoid a major problem could result in years of additional life for your system. Replace your filter with a new one that is compatible with your system on a regular basis to avoid putting unnecessary strain on the system. Consider signing up for an HVAC maintenance contract to ensure that your unit is serviced, cleaned, and adjusted on a regular basis. Check that the thermostat is properly programmed to prevent the unit from running when it isn’t necessary. If your HVAC system fails and you are faced with the prospect of having to replace the entire system, act quickly and obtain several quotes from a variety of servie companies. As previously stated, some larger companies may have units on hand, but your options with other companies may be limited as a result of this. Replace your aging system before it completely fails to avoid a potentially dangerous situation this winter. And while everyone wants to squeeze every last day of operation out of their old system, a new, high-efficiency system may be able to lower your overall operating costs by as much as 30 percent. Because you have planned and scheduled the replacement, you will avoid any disruption to your home’s comfort and will have the opportunity to review all available utility rebates and attractive financing options before making a decision. via Air Check Mechanical Service - https://www.aircheckms.com/ac-installation/hvac-system-prices-and-supply-shortages/ How Do Smart Thermostats Work?With today’s smart thermostats, it is now possible to program your heating and cooling system to maintain the ideal temperature in your home no matter where you are in the building, sometimes no matter where you are in the world! Of course, it is possible that you have experienced a cold or hot room despite the fact that your thermostat indicates that everything should be perfect. A drafty room or one that receives more sunlight in the summer can cause you to constantly adjust the temperature setting, raising your energy bills and making it impossible to achieve the perfect balance. So the best way around this: don’t try to achieve a “perfect balance”. Many homes, particularly older homes, are just not suited to achieving the “perfect balance”. Remote Sensors: The Brains That Make Smart Thermostats Genius!Remote sensors, however, can provide the thermostat with a more accurate picture of the temperature in your home. As is customary, your HVAC system is likely controlled by a single thermostat, which is typically located in a common area such as a living or family room. While new systems still have a single point of control, these can gather information from a variety of different rooms throughout your home by using remote sensors. The majority of smart thermostat options, from such manufacturers as NEST, Ecobee, and Honeywell, allow you to add additional sensors in other parts of the house. Because these remote sensors communicate wirelessly, they are quick and simple to install, even if you have very little mechanical know-how. Remote sensors can also help to balance the heat in a home that has several different types of heating. If you have a fireplace in your home, it can provide a wonderful source of warmth and relaxation. However, if the thermostat is located in the same room as the fireplace, the entire house can quickly become a deep freeze. While you’re relaxing in front of the fire, remote sensors can help keep the rest of the house comfortable as well. While the addition of remote sensors does not provide the ability to control the system directly from each room, it can ensure that your legacy system knows more about the home and works to maintain a more consistent temperature throughout. Certainly, the time when HVAC equipment can address the needs of specific rooms cannot be too far off! Thermostat Control From Anywhere: A Double-Edged SwordIt is an age-old battle to try to keep your house at a comfortable temperature. But it is important to note that constantly adjusting the thermostat up or down can result in premature wear and tear on HVAC systems, as well as wildly fluctuating utility bills. With a properly programmed or learning thermostat, you can help to maintain control over the situation. Knowing when you are at home and when you are away can assist in establishing a baseline for your level of comfort. However, your schedule may shift and you may find yourself wishing for a little more heat in the room you are currently in, but not feeling like getting up and running around the house to make the necessary adjustments. Temperature controls that are WIFI based can be adjusted from any room or any location in the world using a smartphone or tablet. Some smart thermostats now even include voice-controlled virtual assistants that can be instructed to raise or lower the temperature from your phone or any other connected system in your house. You may already have smart devices that can communicate with your thermostat. If so, you should consider upgrading. Consider the example of asking your television to increase the temperature in your home using the Google Assistant. Twenty years ago, this would have been something you saw on an old rerun of the Jetsons. Now, it’s real. While the new methods of changing the thermostat setting from a distance may not put an end to the battle over the thermostat setting, they will provide you with some additional control in your efforts to keep the family comfortable. Of course, as we all know, there is NEVER anything wrong with putting on a sweater. Never! What If Your Thermostat Can’t Achieve A Consistent Temperature?If you are unable to achieve a satisfactory balance of temperature settings that allows you to enjoy your entire home, it may be necessary to consider the supply side of the equation, namely, your HVAC system. Warm blankets and cooling fans will only get you so far if your current HVAC system treats each room the same way in which they are placed. The team at Air Check Mechanical Service can assess your current heating and cooling system and make adjustments to the way each room is supplied with warm or cold air, depending on your needs. Our experts can also recommend improvements to your current systems as well as alternative options such as mini-splits, which can provide targeted heating and cooling to problem areas of your home.

So basically, there are 4 common air duct designs. The first is the plenum or radial duct system. Radial systems have the HVAC unit and return grill at the center of the home with the supply ducts extending out around the plenum like the legs of a spider. The second type is the reducing extended plenum system. As the name implies, the plenum reduces in size as it extends across with the air ducts coming out from either side. The third is the extended plenum system. This time the plenum, which does the distribution or removal of air for the HVAC unit, does not reduce in size as it extends across. The last is the perimeter loop system – a radial system, not as many spider legs, with a supply duct that encircles the building. Good HVAC contractors calculate airflow, determine the types of ducts to use to meet the home’s requirements, and sketch the air distribution system for proper placement of equipment and duct sizing. Typical Air Duct Design FlawsAir Vent Location Not OptimalWhen it comes to air vents, “location, location, location” makes a huge difference. If the air vents are in out-of-sight areas like closets, supply air cannot properly heat or cool the room. Likewise, if the vents are blocked by furniture or some other kind of obstruction, your HVAC system will have to work harder to achieve the desired temperature. This wear and tear will shorten your HVAC system’s lifespan considerably, sometimes making air conditioning repairs extremely expensive. The Central Return ProblemIn an ideal world, there would be returns for every room of the house except bathrooms, and utility rooms. But builders like to save on costs. With only one central return duct to feed the HVAC unit, closed doors will starve the furnace or AC and create a negative pressure environment. Dirty outside air then infiltrates the house through fissures, which can be bad for allergies, among other problems. Too Many Air Ducts Coming Off The PlenumPlenums, as we mentioned, are boxes connected to the heating or cooling unit that fill with hot or cool air and distribute or remove it, usually at a greater atmospheric pressure. What some call a “ductopus” is a poorly designed radial system with air ducts coming off the plenum in all directions, like the tentacles of an octopus. When too many duct branches are connected, air flow can be all around poor throughout the house. Long Duct RunsThis is a common problem with the reducing plenum duct system. Not enough air reaches the room at the very end of the supply duct. The solution is usually to install a bigger duct size. Bad Takeoff PlacementAs air moves from a supply plenum or main duct into a takeoff, it changes direction. Airflow has a hard time making turns at high rates of speed, just as you might in a car going 100 mph. With moving air, we want a gradual and smooth turn since we’re moving really fast. When there is a change in air direction in a duct, it takes roughly 24 inches for airflow to restore its pattern. Takeoffs should thus be 24 inches away from any turns, transitions, or the end cap. Undersized Returns And Undersized SuppliesWhen an HVAC system has undersized returns or undersized supplies it is like breathing through a straw. Air cannot circulate properly, and the unit struggles to heat and cool the building. Improper Duct Installation IssuesIf you suspect your duct work is designed or installed improperly, there can be a host of heating and cooling issues that you never asked for. Take all your problems as a sign that it is time to make adjustments to your existing duct work. The good sheet metal workmanship of the 50s and 60s is long gone. Since the 1970s, air duct installations have been typically a lot cheaper and are generally inferior to the craftsmanship of the past. Here are the common air duct installations issues: Bad Air Duct Seals And ConnectionsRemember that in a typical home, at least 20% of the air traveling through the ducts escapes through leaks, holes, and bad ducting connections. In many cases, HVAC installers are forced to use cheap materials to keep their business afloat. Using cheap seals instead of proper airtight ones leads to noise, dust, draft, humidity, and much more. This is because poorly fastened air ducts can become loose with the motion caused by flowing air. Unbalanced Air FlowPoorly installed ductwork leads to poorly balanced airflow, which leads to hot and cold spots, which leads to higher utility bills. HVAC best practices call for an air balance after installation to determine whether the air is flowing where it’s designed to. If it’s not, dampers can be installed on the duct trunk to adjust air flow. Unfortunately, this is rarely done. Un-Insulated Or Under-Insulated Air DuctsAir ducts are frequently made of thin material with little insulating capacity. Insulation keeps the air inside your ducts at the temperature it should be. In the summer, insulation prevents the cool air condensation that can lead to mold and mildew. In unconditioned spaces such as attics and crawl spaces, the recommended air duct insulation level is R-8. Unfortunately, most air ducts are only insulated at R-2. Unnecessary Ducting BendsJust like the airplane that experiences heavy turbulence within air pockets, air colliding with the duct becomes turbulent and moves slower. A good HVAC specialist will avoid unnecessary bends when installing the HVAC duct system and opt for smaller tree branch type ducts where possible. Twisted, Tangled, & Kinked Flex DuctsThe bottom line is many HVAC contractors that are not Air Check Mechanical Service are too lazy to stretch flex ducts and cut them to fit into place fully extended. Instead, the overly long runs are left twisted, tangled & kinked. Remember the metal rib cage in flex ducts? Now airflow is reduced even more, costing you big money. Unsupported Duct Runs And Butt JointsIt’s a basic fact: flex ductwork cannot be unsupported for more than 4 feet or it will start to sag. The same thing will happen when contractors take two flex duct runs, fit them together with tape, and wrap insulation to hold them together. While this may pass an inspection, neglecting to install a metal butt joint connector creates a weak connection and leads to sagging ducts and escaping air. Air ducts, like almost anything these days, doesn’t last forever. In fact, because of the thin materials, they can be subject to serious wear. Air Duct Wear & TearMoving air is a powerful force. Your air ducts experience wear and tear over time when air is ricocheting off the walls, so unfortunately, they don’t last forever. Expiration dates vary – metal ducts generally last longer than flex ducts because metal is more rigid and its surface allows air to glide, unlike the coil around flex ductwork. That said, the average air duct lifespan varies from 15 to 25 years. As your air ducts age, problems begin arising: Leaky, Corroded DuctsOld seals will erode with enough wear and tear, letting air slip out (or in). If moisture gets into the air duct, it will corrode the ducts over time. You’ll see the same corrosion if your basement or crawl space is overly humid, or if water is leaking from your roof, plumbing, or humidifier. Unsupported flex duct runs are more likely to sag, and condensation will gather in the dip. Dirty & Clogged Air DuctsThe nature of duct work is unfortunately that one duct problem leads to many. If your indoor air is dirty, the impurities can accumulate inside your ducts and, if the debris is substantial, clog them. This is made worse with holes, loose connections, and general uncleanliness in your home. Molds In The Air Duct Are Hazardous To Your HealthWarning: do not let moisture enter your air ducts. Mold will form. And while it may not physically deteriorate your air duct, it will affect the quality of your air and by association, your lungs. Supply vents will blow mold spores to every room. And in worst case scenarios, this could lead to the decay of furniture or walls. Be sure to contact Air Check Mechanical Service to evaluate all of your options during a ductwork repair. via Air Check Mechanical Service - https://www.aircheckms.com/ac-repair/ac-ducts-and-your-hvac-system-part-2/ AC Ductwork And Your HVAC SystemThere’s a hidden system in your home dedicated to circulating your air. Don’t know anything about your ductwork? You’re not alone. When homes have air duct issues that can cause cold or hot spots, homeowners tend to avoid those rooms and also, avoid the problem. And when they do, without realizing it, they’ve lessened the liveable amount of square footage in their homes. It’s not a good situation. From uneven room temperatures, to excess dust, and high electricity bills, air duct issues can cause daily despair to homeowners and renters alike. What follows is a homeowner’s guide to AC ductwork; we’ll explain everything you need to know so you can rid yourself of those burdensome cold or hot spots and reclaim your rooms. What’s An Air Duct?Check this out – Air ducts, or HVAC ductwork, or AC ducts, are conduits that supply warm or cool air to heat, ventilate, and cool each room in your home. Air ducts are connected to the HVAC unit which filters then heats or cools your home’s air before sending it off. Air ducts are a vital part of your HVAC system, providing thermal well-being and good indoor air quality to your family. Next, let’s see what air ducts are made of. Types Of Air DuctsSheet Metal DuctingGalvanized steel or aluminum air ducts can be round, oval, or rectangular, depending on your home and its design. Sheet metal HVAC ductwork is the most durable and is also least likely to harbor mold. Metal air ducts are practically rustproof, especially galvanized steel with its zinc coating. Flex DuctSimply put, flex ducts are made from a steel wire spiral, wrapped with a polymer (a bendable plastic), and surrounded by insulation. This kind of ductwork is inexpensive, lightweight, and easy to install. Flex ducts work wonders in tricky spaces where more rigid ductwork will not do. While typically a duct system won’t contain all Flex Duct, it may be used sporadically in locations where sheet metal is tough to place. Fiberboard DuctThis type of duct has two layers: compressed resin-bonded inorganic fiberglass is encased in foil to prevent air and water vapor from penetrating. Typically, this air duct is the least expensive, prevents noise, and is already well insulated when it is first installed. The downside? The rough fiberglass surface inhibits airflow. Admittedly it’s not an incredible level of airflow stoppage, but it does make a difference in air flow. Beware – old fiberboard ducts aren’t treated to prevent mold or mildew and should be replaced immediately. If you suspect you have old fiberboard ductwork, do not attempt to clean it. The surface damage will release fiberglass into the air and throughout your home. How Air Flows In A Forced Air Duct SystemIn HVAC systems, your air goes through a cycle. A negative pressure in the ducts sucks the air in, passing it through a filter in the system. The cleaned air is heated or cooled and sent back to the areas of your house where it stays until it’s cycled again. Return DuctsContrary to popular belief, almost all HVAC systems get their air from inside the building. Return ducts extract air from the living spaces back to the HVAC unit, feeding either your furnace or air handler. Return vents are usually larger than supply vents and are called grills. A filter is often installed either deep inside a return duct or right at the return grill to protect your HVAC unit from impurities. Supply DuctsSupply ducts blow warm or cool air to an area inside your home. Supply vents often have dampers to control the flow, called registers. Supply registers will often be installed near windows or doors to better counteract the loss of heat or cold, and two or more supply registers may be installed in larger rooms to evenly distribute your heated or cooled air. We’ve looked at duct systems, but what happens when you air ducts aren’t up to standards? Signs Your Ductwork Is BadHot & Cold SpotsThis is the ultimate tell-tale sign you have air duct issues. You’ve likely felt it before. You walk into a room and it’s too hot, or you walk down the stairs and it’s noticeably colder, often at least more than 3 degrees. If this is the case, use a thermometer to confirm what you’re feeling. Once you’re certain of the discrepancy you can call an HVAC professional from Air Check Mechanical Service. They’ll pinpoint the cause, come up with a plan, and put the plan to action. Fair Or Poor Indoor Air QualityThere are two big signs your air quality is compromised. First, the dust collection in your house makes it look like you’ve been in a serious dust storm. Second, everyone is sneezing, especially any family members that have allergies. The main factor you should know is that dust or pollen can seep into your ductwork through holes or loose connections and infiltrate your home. Thus, the sneeze factor. According to the National Comfort Institute, air duct problems are so common, a typical HVAC system only delivers 57% of its rated capacity. One quick call to Air Check can change that all! High Utility BillsUp to 30 percent of the air in your ducts may be escaping before it can do what it needs to do, i.e. heat or cool your rooms. When conditioned air leaks out or heated air is lost through under-insulated air ducts, the charges will show up on your utility bill. The scary part is you probably won’t notice unless there is a major disruption. You may eventually discover through a utility usage report that you are using way more electricity than other similar homes in your neighborhood. Little Or No Air Flow From Supply VentAn easy way to check for obstructed air flow is to place a piece of paper in front of the supply opening. If the paper doesn’t bend or flutter at all, something is preventing airflow. If you’re lucky, the damper on your register is closed and simply needs reopening. If that doesn’t work, you may need to call an HVAC expert. Loud NoiseWait a minute, doesn’t your heat pump or air conditioner make noise when it’s running? Yes, but the sound shouldn’t annoy the living heck out of you. If you hear loud rattling or whistling, you probably have loose, disconnected, or damaged air ducts. Don’t ignore it or it’ll worsen. This has been part one of AC Ductwork and your HVAC system. Don’t forget to tune in next week for part 2! via Air Check Mechanical Service - https://www.aircheckms.com/ac-repair/ac-ductwork-and-your-hvac-system/ Generally speaking, there are a lot of us that believe that allergies are caused primarily by pollen and pet dander. As a result, why do people who live and work in cities continue to suffer, despite the fact that pollen-producing plants and furry critters are in much shorter supply than in the suburbs? Many people believe that poor indoor air quality is the cause of their problems (IAQ). An AC maintenance service can assist in reducing contaminants and allergens in indoor air, allowing you to breathe more comfortably. Talking About Indoor Air Quality, Allergies, and Air Conditioning MaintenanceIt doesn’t matter if you aren’t familiar with the pollution statistics; seeing the brown haze hanging over the city gives you a good indication of the quality of the air you are breathing outside. However, it may come as a surprise that the air quality inside buildings in Southeast Houston is frequently far worse than the air outside. Poor air conditioning maintenance is one of the primary reasons for this, and is in fact one of the most significant contributing factors. It’s true: According to the Occupational Safety and Health Administration, poor maintenance of HVAC systems is one of the leading causes of poor indoor air quality. Consider this: your HVAC system filters a lot of the air that you breathe inside your home or office. A good HVAC system is intended to provide what is known as return air or makeup air to your space, which essentially means that they will be bringing in fresh outdoor air into your home. As a result, all of these pollutants are entering the home or business environment and remaining there. AC contaminants can become trapped in your equipment and ductwork and accumulate over time when you fail to perform regular maintenance. When poor air conditioning maintenance results in moisture problems, the situation becomes even worse. Add insult to injury by encouraging the growth of potentially harmful mold, mildew, bacteria, and viruses in your home or business. This stuff isn’t just minor – it can be quite dangerous to your short AND long term health. Having a better understanding of where your allergy symptoms are coming from is quite critical. It’s important to remember that we’re not just talking about sniffling and sneezing here. There are many different symptoms associated with poor indoor air quality, which include the following:
There are three ways that regular AC maintenance can help alleviate symptoms.Investing in a regular preventative maintenance program for your HVAC system helps to remove dirt and pollutants from your system as well as the air you breathe. Here’s how it’s done: 1. Accessing the filters (and choosing the right ones)When was the last time you had your air conditioning filter changed? Did you even realize you had an air conditioning filter? If you have an air-cooled system (which frankly almost every building in Southeast Houston does), then yes, you have one. Its purpose is to prevent dust and grime from clogging up the equipment and causing undue wear. However, if your air filter is not changed on a regular basis (the frequency depends on your system, where you are located and its usage), it will eventually become blocked, and the grime will end up in your equipment, ductwork, and indoor air. Preventative air conditioning maintenance involves the cleaning or replacement of the filters in your air conditioning system, depending on the type of filters that are currently in use in your system. Another thing to keep in mind is that if you have allergies, you can use a special type of filter that will filter out even more allergens from your environment. 2. Controlling the humidityRemember that sediment clogs are not the only source of water accumulation and mold growth, as previously stated. In the event that your air conditioning system is not performing as well as it should in terms of removing humidity from the air, you may find mold growing in unexpected places throughout your home, including damp spots where you will never notice it. Certainly, any black growths along walls or in corners should ring the alarm that something bad is happening. AC maintenance is the most effective method of preventing excessive humidity, which can lead to mold and mildew growth. When you have your air conditioning equipment inspected on a regular basis, problems such as humidity control can be discovered and corrected before you suffer any permanent damage to your health or your building. The majority of the time, a system tune-up or the replacement of worn parts can resolve the humidity issues that are causing allergy symptoms. 3. Remove contaminants and standing water from the environmentStanding water in any part of your home is something you should avoid at all costs if you have asthma or allergies. Did you know that your air conditioning system may be generating lingering moisture? It is possible for condensate lines and drain pans to become clogged with grime and sediment if regular AC maintenance is not performed. That means that the moisture removed from the air by your air conditioning system has nowhere to go. Water begins to accumulate in the pan, and eventually leaks out, causing water damage to the surrounding area. Eventually, all of that accumulating water becomes a breeding ground for mold, mildew, and bacteria, which accumulates on your equipment and eventually finds its way into the ductwork. Before you know what’s going on, you’re inhaling a toxic cocktail of noxious substances. As a result, what happened? Not to mention the possibility of system failures as a result of allergy symptoms. Maintaining your drain lines and pan on a regular basis helps to avoid water problems by clearing them of all the sediment that can cause clogs and water accumulation. It is critical to understand that investing in HVAC maintenance actually saves you money while also improving your comfort and reducing your allergy symptoms. Regular maintenance has been shown to lower repair costs, extend the life of your equipment, and even lower your electric bills. via Air Check Mechanical Service - https://www.aircheckms.com/ac-maintenance-services/ac-maintenance-service-and-your-allergies/ HVAC Preventive Maintenance Contracts: Frequently Asked QuestionsIs it possible that you were recently burned by high HVAC repair costs? Alternatively, have you recently purchased a new HVAC system and want to get off to a good start by taking proper care of it? It’s possible that you’re considering investing in regular service for AC repair and exploring HVAC preventive maintenance contracts for the first time if this is the case. If you’re reading this, it’s likely that you have questions… and you may not be quite ready for a sales pitch just yet, so you’re hesitant to begin making calls. Listed below is some useful information on what to expect from an HVAC preventive maintenance contract, as well as how to get started evaluating your options. Listed below are a few of the most frequently asked questions we receive from first-time purchasers of HVAC preventive maintenance contracts, as well as the types of responses you can expect from a reputable and qualified vendor in this field. 1. What are the most common services covered by HVAC preventive maintenance contracts?A preventive maintenance contract for your HVAC system includes a number of regularly scheduled maintenance visits each year, during which a technician will thoroughly inspect your equipment, clean it, and test it to ensure that it is in proper working order. The number of visits required and the list of tasks to be completed will be determined by the age and type of equipment you have, as well as the operating conditions and usage specifications. Consider the difference between the maintenance requirements of a hospital HVAC system that is constantly running 24 hours a day and the requirements of a small unit for an office that is only open from 9 to 5 on weekdays: Also available are contracts that cover more than just routine maintenance: a full labor contract covers all of the labor required for repairs or replacements, as well as routine maintenance, but you are responsible for the cost of any replacement or repair parts. In terms of insurance, a full coverage contract is the ultimate policy, as it covers all parts and labor, as well as emergency service and preventive maintenance. 2. When will I be required to make a payment?If you are signing a smaller contract, you will almost certainly be asked to pay the entire amount up front. When it comes to HVAC preventive maintenance contracts that cost more than $1000, you can frequently choose the payment terms that are most convenient for you: monthly, quarterly, or yearly. 3. What if I have to cancel my reservation?The majority of vendors are aware that there are times when a contract must be terminated for unavoidable reasons, and they prepare accordingly. Many service providers will allow you to cancel your contract if you give them at least 30 days notice. 4. How long does it take you to respond?The majority of vendors do not guarantee response times when it comes to HVAC preventive maintenance contracts. They should, on the other hand, be able to provide you with realistic expectations for repair response times. For example, if you call first thing in the morning, you can expect someone to show up the same day you called. 5. Will I be given priority treatment?This is one of the advantages of HVAC preventive maintenance contracts that first-time customers may not be aware of or anticipate. If you are a loyal and frequent customer, you will be moved to the front of the queue if you have a repair issue, allowing you to receive faster service overall. 6. Will I always be assigned to the same service technician?It is not only reassuring to have the same service technician show up time and time again, but it is also time-saving to do so. He is familiar with the procedure, he is aware of the location of the equipment, and he is aware of what needs to be done. However, the downside is that what happens when that guy goes on vacation or is absent due to illness? When a service company assigns a dedicated team to your account, you will be better off. You’ll have that familiarity with people who understand what you’re going through, but you won’t be reliant on a single person to always be there for you in that way. 7. Will I be notified when it is time to schedule my regular maintenance?Some companies will send you a postcard to remind you to schedule your regular service, so you can post it on your bulletin board and hope that you will remember to call them when you get the chance. The vendors who provide the best service will contact you at the beginning of each month when you are due for service and will work with you to get it set up as quickly and easily as possible. 8. Can I lock in a rate for a period of several years?If you’re looking to manage expenses over a longer period of time, you may be able to negotiate a 2- or 3-year agreement with a larger contract. If you’re confident in the vendor’s services, signing a multi-year contract can save you money while also providing you with peace of mind, knowing that you can reliably budget for your HVAC maintenance costs. 9. Is it possible to negotiate specific terms of the contract in order to meet the specific needs of my company?The answer should be yes if the company is truly concerned with providing excellent customer service. In fact, this is one of the most reliable ways to determine whether or not you’re dealing with a company that will rise to the occasion and complete the task at hand. A common example is a restaurant owner who does not want service personnel cleaning the vents in his or her dining room during lunch or dinner service hours. Because of this, the HVAC service company may need to arrive early in the morning before your business is ready to open. The hours during which your service is provided should be negotiable in order to accommodate your requirements. 10. Is it possible for my contract to be automatically renewed?Generally, your contract will automatically renew at the end of its term with a small cost of living price adjustment included. The absence of a renewal clause in your contract may indicate that the vendor offered you a rock-bottom price in order to win your business, which they will likely be unable to meet the following year. The amount you pay for year two may be significantly higher than the amount you paid for year one. One of the most important things you should know before shopping for an HVAC preventive maintenance contract is that they are not one-size-fits-all solutions. According to the equipment you have, the level of coverage that you are comfortable with, and the needs of your company, you should customize the terms of the agreement. via Air Check Mechanical Service - https://www.aircheckms.com/ac-repair/hvac-preventive-maintenance-contracts-frequently-asked-questions/ HVAC Company Problems You Should Never TolerateAs a business owner or manager, you may find it easier to simply ignore nagging concerns about your HVAC service provider when you have so many other pressing issues on your mind. The problem is that over time, those things that were merely irritating begin to escalate into critical issues that cost you money and even threaten your company’s survival. In most cases, unless you live in a very remote area, you will have many options when it comes to selecting an HVAC service company. You have to ask yourself why you should accept less than you deserve, or worse, less than you’re paying for when the market is competitive. Here are some of the most common reasons why your HVAC service provider may be letting you down, as well as reasons why you should repair or rethink your relationship with him or her. Putting off routine maintenance tasksIf you have a preventative maintenance agreement, are you confident that your HVAC service provider is performing all of the tasks for which you have paid them to do? Vendors’ definitions of “preventive” tasks can differ slightly from company to company. Some people may suggest that you simply change your filters and belts and call it a day. Another important part of a quality HVAC maintenance visit is checking the refrigerant levels as well as inspecting the electrical connections and condition of parts, cleaning the coils, and checking the drain lines and pans. Again, this depends on the contractor. Not showing up when they say they willInevitably, there will be unavoidable reasons for service providers to arrive late, such as traffic congestion (an obvious to everyone in the Houston Texas area), unexpected issues at a previous job, or other unforeseen circumstances. However, the best service companies are well-versed in how to minimize these issues. Take note of the following: If the response time of your HVAC company is consistently poor, you must wonder if the work they perform will be equally unreliable in the long run. Not preparing you for the eventuality of equipment obsolescenceIf your company has a large number of different pieces of HVAC equipment scattered throughout your facility, the age and condition of each piece is likely to vary. There will be times when your air conditioning or heating equipment fails without warning, but you can minimize the amount of time your equipment is down by planning ahead of time. In order to inform you in advance of which equipment items are approaching the end of their useful life and should be replaced within a specified time period, your HVAC service provider should be willing to collaborate with you. Purchasing ahead of time also allows you to shop around for the best deal. Several visits to the same location to resolve the same issueIt is possible that you require a new service provider or new equipment if you continue to have the same problem over and over again (and maybe both). While it is always possible that equipment that keeps failing is past its useful life, an HVAC service company that doesn’t do new installations may be taking advantage of you by charging you for all of the repairs rather than recommending replacement. Alternatively, you may be dealing with a technician who is insufficiently qualified to properly diagnose and fix your problem. Complaints about nagging comfort issuesYour HVAC service company may be overlooking a problem in your space if you continue to experience hot and cold spots, odor problems, or uncontrolled humidity issues after your regular maintenance visit. It’s possible that you’re dealing with system design or configuration issues that need to be addressed. Make sure to inform your service provider of any ongoing issues you are experiencing and to request a more thorough inspection in order to determine the source of the problem. It is taking an excessive amount of time to obtain parts.Especially if you have older or off-brand equipment, some smaller HVAC service companies may not have a large enough parts inventory to keep what you need on hand at all times. Consequently, whenever you require a repair, you will have to wait for them to order the necessary parts. Use an HVAC service provider who has a large parts warehouse as well as relationships with several parts suppliers in the area, as this will allow your repairs to be completed more quickly. The failure to provide adequate explanations for repair issuesIf so, your maintenance agreement may be written in legalese, making it difficult to understand what is and is not covered by the agreement. You get scribbled work orders with little or no explanation as to what exactly needs to be done or why it needs to be done. In the worst case scenario, your tech may tell you what’s wrong by using technical jargon that he knows perfectly well is foreign to you. This unprofessional behavior on the part of an HVAC service provider must not be accepted! It is your right to have any and all repair and maintenance issues explained to you clearly and in a language that you understand. Overall SloppinessThe fact that this appears to be a minor detail indicates the presence of more serious issues that could be life-threatening. Have you ever noticed that your HVAC service technician appears disheveled, scatters his tools around the room while working, and leaves a mess behind when he’s finished? That shambles has the potential to create a safety hazard in your workplace. And think about it: don’t you find it easier to put your trust in a technician who is dressed professionally with a name tag and tool belt? Remember that the manner in which a technician treats his or her clothes and tools can reveal a great deal about how he or she will treat your equipment. Not fully comprehending the requirements of your home or businessThis is a common area in which your HVAC service company may fall short of your expectations: by taking a one-size-fits-all approach to service rather than operating in accordance with the specific needs of your home or company. A service company should be willing to work around your schedule, for example, if you own a restaurant and are unable to have a service technician performing maintenance during business hours. In order to ensure that your system design and configuration is appropriate for the usage and occupancy of the space, it is also necessary to understand your business. via Air Check Mechanical Service - https://www.aircheckms.com/ac-repair/hvac-company-issues-you-should-never-tolerate/ |
