Reasons You Should Consider Replacing Your Home’s Old Furnace

Posted by on Oct 13, 2016 in Uncategorized | Comments Off on Reasons You Should Consider Replacing Your Home’s Old Furnace

If you have an older home, and the furnace in it is also old, you may be putting off the installation of a new furnace for saving money. Your furnace may be making odd noises or not heating as well as it used to. The older your furnace gets, the more likely it is to have serious problems, some that could cost more than your entire heating system is worth. Find out more about some of the reasons you should seriously consider the installation of a new furnace. No Blower, No Warm Air Circulation The blower is essential for your furnace to heat your home because it circulates the generated warm air into the ducts so it can make its way to the vents inside your home. When the furnace is old, the blower and its motor are probably just as old. While the replacement of a blower or its motor isn’t likely going to break the bank, it is senseless to have a new one pout into a furnace with several other old components that are likely going to break down sooner than later. Preventing Carbon Monoxide from Entering Your Home A heat exchanger is a piece of metal inside your furnace that is made to heat up, the element that warms the air you feel coming out of your vents. When a heat exchanger is old, it is at high risk of cracking. A cracked heat exchanger will cause carbon monoxide to leak into your home, a serious and deadly safety hazard. If you learn your older system’s heat exchanger is cracked, your best option is to replace the entire system. If anyone in your home has started having headaches, nausea, and burning eyes, carbon monoxide could be causing the problem. When Your Furnace’s Brain Gives Out When the circuit board in your older furnace fails, it is time to get a new furnace. The circuit board is your furnace’s “brain,” or its controls governing every aspect of your furnace’s operations. If your furnace is old, a new circuit board may be hard to find. Also, if the parts in your furnace are old and also likely to wear out faster than the new circuit board, there is no point in spending the cash on a new “brain” for it. Maintaining your furnace can help to increase its life span. However, after so many years, a furnace will need to be replaced because of wear and tear. If your furnace is old and has starting acting up, contact an HVAC professional such as Butler Heating & Air today for an inspection so you can see whether it is time for a new...

Pros And Cons Of The Different Types Of Heat Pumps

Posted by on Jul 18, 2016 in Uncategorized | Comments Off on Pros And Cons Of The Different Types Of Heat Pumps

Heat pumps offer an alternative to traditional air conditioner units by utilizing heat shifting rather than cooling and heating generation. The pump transfers warmed air into and out of your home according to the interior temperature needs and the exterior air temperature in order to make your home comfortable. There are a few different types of heat pumps available that differ primarily in how the unit transfers that heat. Each type of heat pump has its own pros and cons that you need to consider before purchasing a unit. Not sure what type of unit seems right for your home? Contact an HVAC repair and installation company for assistance. Air-to-Air The most common type of heat pump transfers air-to-air using electricity as the fuel source. This means that the unit moves the air from inside or outside the home in the opposite direction. This type of heat pump comes in either the traditional ducted version that uses your home’s existing vent system or the ductless mini-split system that works well if you don’t have an existing vent system. An air-to-air heat pump can offer an energy savings of up to 50 percent compared to traditional heating and cooling systems. The unit also works well as a dehumidifier to ensure that the transferring air doesn’t come with added humidity. Geothermal Heat Pump Geothermal heat pumps can either utilize the temperature from the surrounding ground or from a nearby water source. A geothermal heat pump can reduce energy costs by up to 60 percent and can be used in a wider variety of climates than air-to-air models due to the relative consistency of ground and water temperatures compared to air. On the downside, geothermal units are often more costly upfront to install due to the complexity of the system. But the low maintenance nature of the unit and the higher savings costs can make the unit a better deal in the long run. Absorption Heat Pump Absorption heat pumps work similarly to air-to-air heat pumps but use a different fuel as the source. Instead of using electricity, the absorption heat pump uses natural gas or propane to fuel the system. The unit also includes an important watered down ammonia solution that essentially works as the heat pump’s refrigerant. The evaporation, or lack thereof, of the ammonia helps determines whether the unit performs heating or cooling functions. Absorption heat pumps can work in a wider range of temperatures than a traditional air-to-air heat pump. The use of fuel can save you or cost you on utility costs depending on the costs of the specific fuel in your area. For an HVAC contractor, contact a company such as One Hour Heating & Air...

Air Conditioning: The Costly Effects Of Refrigerant Overcharge

Posted by on Jul 18, 2016 in Uncategorized | Comments Off on Air Conditioning: The Costly Effects Of Refrigerant Overcharge

Since air conditioning systems are closed systems, an increase volume of refrigerant in a given system is bound to affect its overall pressure. Areas that are supposed to be low pressure areas will be converted into not-so-low pressure areas and high pressure areas will end up turning into abnormal high pressure areas. This, in addition to the fact that excess refrigerant can affect the change-of-state process, can end up costing you. Refrigerant overcharge and air conditioning efficiency Cooling usually takes place in the evaporator coil area when the refrigerant absorbs heat from the warm air passing over the coils. To maximize this process, manufacturers usually ensure that the evaporator coil area has the lowest pressure possible. This is important as it ensures that the liquid refrigerant changes into a gas at much lower temperatures. This usually allows the refrigerant to absorb more heat and thus making for an effective air conditioning process. However, when the system has a more-then-necessary amount of refrigerant, the resulting increase in pressure usually causes the refrigerant to change states at way higher temperatures. It won’t absorb as much heat as it should. This usually makes for an inefficient cooling process. Since refrigerant overcharge reduces the amount of heat absorbed from air, the air that eventually gets dumped into an air conditioned space won’t be as cold as it should be. To reach a given temperature, the air conditioning system will have to work for longer. This requires more energy and will thus lead to an increase in the energy bills that one has to shoulder. There is also the fact that working longer-than-normal hours to make your home comfortable will put a strain on your system, something that will then shorten its lifespan. Refrigerant overcharge and the damaging effects of liquid slugging Excess amounts of refrigerant in an air conditioning system will increase the risks of the refrigerant being in places where it is not supposed to be. The volume of the refrigerant that is available in the evaporating coil area at any given time is also bound to be more than necessary. As a result, the change-of-state process that is required to convert the refrigerant from a liquid into a gas is unlikely to be sufficient to convert all of the refrigerant in the evaporator coil. This will then have the effect of causing some of the refrigerant to arrive at the air conditioner’s compressor while still in liquid form. This is what is called liquid slugging. The arrival of the refrigerant while still in liquid form usually causes problems for the compressor. This is because the compressor’s parts aren’t strong enough to handle a liquid. Therefore, any attempt by the compressor’s motor to compress the liquid refrigerant usually leads to the damage of its piston, scroll spirals and any other moving parts. This usually calls for unnecessary repair costs that you will have to take care of. To learn more, contact an HVAC contractor in your...

Is Your Electric Furnace Overheating? How To Prevent It From Happening

Posted by on May 28, 2016 in Uncategorized | Comments Off on Is Your Electric Furnace Overheating? How To Prevent It From Happening

If you have an old furnace that is powered by electricity instead of gas, you may have issues with the furnace overheating at some point. This not only can damage the furnace itself, but be a potential fire hazard. Sparks can be created that will burn wiring in the furnace, and the soft air filter can become flammable if a fire spreads. Here are some tips that will help prevent the overheating from happening. Why Cleaning The Electric Furnace’s Heating Element Is Important If your old furnace is maintained and cleaned every year, it can still function quite well despite its old age. What you need to be concerned about is if the furnace’s heating element starts to have a build up of debris on it. This will cause the electric furnace to not operate correctly. The parts that you need to watch out for is the coil inside that resembles the heating coil inside a toaster. Since this heating element can get extremely hot when it is in use, it is very important that it doesn’t have anything touching it that can potentially catch on fire. This includes small dust particles, dirt, or other debris. How To Clean An Electric Furnace’s Heating Element Start by turning off all power going to your furnace, which can be done at your home’s circuit breaker to be certain that the power is off. Locate the door that is covering the heating element on the furnace and remove it. Give the heating element a visual inspection. Do any of the coils look frayed, loose, warped, or dented? If so, you should have a professional furnace repair service come replace the coil for you. A coil that is damaged in this way is a fire hazard. If the coil is looking like it is free of damage, you can move on to cleaning it. Use a rag to wipe off the area around the heating coil inside the electric furnace, being careful not to shift the coil out of its position when doing so. This is because the coil can become loose from its connection point. Carefully remove dust and debris from the coil with a feather duster. The soft tips will not damage or snag the furnace’s very delicate heating element this way Put the access door back on, turn on the power, and everything should be good to go. Observe the furnace for a little bit to make sure it is not overheating. If it does, you could have a bigger problem at hand. You will need the help of an HVAC repair company to figure out what is wrong. Contact a business, such as Bill’s Heating & Air Conditioning, for more information....

What Does It Mean When Your Air Conditioner Is Still Making Noise While Off?

Posted by on Apr 11, 2016 in Uncategorized | Comments Off on What Does It Mean When Your Air Conditioner Is Still Making Noise While Off?

If you have an air conditioning system with an outdoor compressor, you may have recently noticed that your fan keeps running even after the air conditioner itself is no longer running. Besides being noisy and distracting, a constantly running fan can damage your compressor, run up your electricity bills and indicate a serious problem within your system. Once you realize your fan is running when it shouldn’t be, walk through these four steps to begin diagnosing the issue.  Adjusting Your Settings Many air conditioning systems have separate settings for the primary fan. This is usually set to ‘automatic,’ meaning the fan kicks on or off whenever the air conditioner does. However, this setting may have accidentally been switched to ‘on,’ meaning it won’t turn off again until manually switched. If you are lucky, this is all you will need to do to put your fan and overall system back in working order.  Checking the Accuracy of Your Thermostat Another minor problem that can impact your fan is the thermostat, which communicates with your air conditioning system as the temperatures shift in your home. If your thermostat is sending or receiving faulty signals because of a shorted wire, your fan may never receive instructions to shut down. Try tuning your thermostat to its hottest setting; if the fan is still blowing after a few minutes, you likely need to replace the thermostat. Otherwise, you will need to start investigating problems with the system itself.  Replenishing Your Refrigerant In some cases, your whole system may be running because it is unable to cool your home adequately. This is typically caused by low refrigerant levels, impeding your system’s ability to chill air before pumping it into the house. Contact your local HVAC contractors or repairmen to top off the refrigerant in your system and make sure there are no leaks. Refrigerant is dangerous to handle, so don’t attempt to check or replace it on your own.  Examining the Contactor Switch After you have tried all of the above steps, your most likely culprit is the contactor switch that sits between your indoor and outdoor units. This switch is what translates signals from your thermostat and controls the flow of electricity to its various components. If one of the wires attached to the contactor shorts, your fan may be left spinning permanently. A mechanical failure that locks the contactor switch in place can also cause this issue. Whenever you suspect that your air conditioning system has a broken component, you may be better off relying on professional contractors to make the repairs for you. Not only will this guarantee your own safety, but it can also maintain the validity of your warranty and ensure that your system has no other underlying problems that will surface later.  If none of these solutions seem to help, contact a professional company like Advanced Heating & Cooling to diagnose the issue for...

Defects In Your Ducts That Cause Inefficiency And Poor Air Quality

Posted by on Dec 8, 2015 in Uncategorized | Comments Off on Defects In Your Ducts That Cause Inefficiency And Poor Air Quality

If you notice that it is colder this winter than in the past, the problem might be with your air ducts. The quality of your air ducts affects the air quality of your home and how energy-efficient your home is. An efficient HVAC system is based on having a balanced air flow. An imbalanced airflow can create negative pressure that can pull heat and pollutants into your ducts. Dirty Air Ducts Your air quality inside your home will be significantly worse if you do not keep your air ducts clean. By keeping your ducts dirty, germs and dust will be circulated more throughout your home. Fortunately, there are companies specialized in cleaning air ducts. Poor Insulation If you notice that your energy bills are very high, your air ducts might not be properly insulated. Even if you did have adequate insulation, your insulation might have deteriorated and is no longer protecting your ducts from heat loss. If you have insulated flexible ducts, make sure that the insulation is not torn or that the ducts are not twisted or damaged. If the ducts are kinked, your home will have much less airflow. Leaks At the location where your register connects to the ducts, there must be a proper seal. Otherwise, there might be a leak and heat loss. You may also have a leak resulting from a crack or hole in the ducts. This opening can significantly reduce the efficiency of your ducts. Depending on the location of the leak, pollutants can bypass your filters and enter your home. Your energy bills can become much higher as well when hot air from your attic or cold air from your basement gets pulled into your ducts and circulated throughout the rest of your home. This problem can force your furnace to work harder and raise your energy costs. Improper Design Sometimes, your ducts were not designed properly in the first place. The ducts need to be sized correctly. They need to pass through conditioned spaces or the heater will not function as efficiently. If your ducts are not installed properly, your ducts might also have leaks. Also, if your ducts are not properly balanced, not enough air will be traveling to each room. The best solution is to contact a duct specialist that provides air duct cleaning and repair services. The specialist will be able to pump dirt and debris out of your home and will...

Commercial HVAC Maintenance Is About More Than Temperature Control

Posted by on Nov 11, 2015 in Uncategorized | Comments Off on Commercial HVAC Maintenance Is About More Than Temperature Control

While a dirty home air conditioner may cause illness in several people, a poorly maintained commercial HVAC unit can potentially cause hundreds of people to become ill, and may even cause death. At the very least, it can cause customer and tenant dissatisfaction and complaints about things such as uncomfortable temperatures and foul odors. Proper regular professional HVAC maintenance can prevent a number of potentially dangerous problems. Airborne Illnesses When you mention air conditioning and illness in the same sentence, you can’t help but think of the outbreaks of Legionnaire’s Disease that have occurred over the years. The bacterium that causes this disease, Legionella, was first discovered in 1976 when an outbreak in a Philadelphia Legionnaire’s convention killed 34 people. These bacteria breed in water such as that found in evaporative condensers of modern air conditioning cooling towers. To prevent the growth of Legionella, commercial water towers should be disinfected, not simply cleaned, on a regular schedule.  Inconsistent Airflow In commercial buildings, there may be limited access to ductwork, especially between floors. This can make detecting leaks difficult and lead to hot and cold spots within the building. The U.S. Department of Energy reports that a standard ductwork system may lose up to 40% of its air from leaks. A commercial HVAC professional can locate and fix leaks before they become a serious problem for you, your customers or your tenants. Efficiency Loss An inefficient HVAC system can run up a substantial electric bill. Simply having a professional clean your condenser and evaporator coils twice a year can improve your efficiency up to 16%. Improperly operating dampers are another problem that can cost you money and affect indoor air quality. They need to be cleaned and well lubricated a few times a year to ensure optimal operation. Poor Indoor Air Quality and Odors Something as simple as a dirty air filter can drastically affect indoor air quality. Odors can be caused by stagnant condensed water, overheating, or melted debris on the heat exchanger. Indoor air pollution from dust and mold can contribute to respiratory illnesses such as asthma and emphysema, causing lost workdays and decreased productivity.  As you can see, a poorly maintained commercial HVAC unit can be costly in the long run. Most of the problems can easily be avoided by having regularly scheduled professional HVAC maintenance. Call a local HVAC specialist like Soco Air Conditioning to have your system thoroughly...

Why Your Air-Conditioner Is Losing Its Efficiency, And What You Can Do About It

Posted by on Nov 9, 2015 in Uncategorized | Comments Off on Why Your Air-Conditioner Is Losing Its Efficiency, And What You Can Do About It

Has your air conditioner lost its efficiency? If your AC is not cooling or heating your house as well as it used to do soon after installation, but it is still running, then there is something interfering with its operations. Here are three common culprits of reduced AC efficiency, and how to combat them: The Evaporator Coils Are Dirty The air conditioner keeps your house cool by drawing heat from the air that blows over the evaporator coils. Different debris, such as dirt and pollen, may accumulate over the evaporator coils. Accumulated debris reduces the AC’s efficiency since it interferes with the airflow over the coils. Not only that, but the dirt may also make the air conditioner run hotter than normal, which reduces its useful life. Thus, regular cleaning of the evaporator coils is essential to maintain efficiency.   Leaking Ducts Air ducts are responsible for conditioning your house (heated or cooled) air around the home. Therefore, a leak in any part of the duct reduces the amount of conditioned air flowing around the house, which affects the efficiency of the AC unit. Since air can flow out of the smallest cracks or holes, and these ducts are usually hidden from view, you may be dealing with leaking air without knowing for a long time. Here are some of the symptoms that may point to leaking ducts: Some rooms are significantly cooler than others Some rooms are stuffy You can see tangled flexible ducts (for example in the crawlspace) Consult a technician to locate and plug the leaks. Low Refrigerant Levels The refrigerant absorbs heat from the air passing over the evaporator coils; this is how it cools the air. The continuous flow of the refrigerant is necessary to control your room temperature. This will not happen if the refrigerant level is inadequate. Apart from inefficient cooling, low refrigerant levels may also lead to compressor motor damage. This happens when the motor becomes overheated since the refrigerant supposed to cool it is inadequate. Have your air conditioner technician check your refrigerant levels, and any possible leakage, that may reduce your unit’s efficiency. This check is especially necessary with old ACs whose systems have degraded over the years. Most of these are problems that a maintenance technician will detect during routine servicing. Therefore, regular servicing and cleaning is necessary to maintain your air conditioner’s efficiency. Ask the air conditioning technician for other tips for maintaining your unit’s...
