What Is a Heat Pump, and Why Should You Have One?

Monday, June 8th, 2015

If you are in the market for a new air conditioning system, you actually have more options than you may think. It’s not just a matter of choosing between different brands and efficiency ratings. You can also find air conditioners with variable speed settings, advanced programming options, or even units that can heat or cool your home. This latter type of unit is called a heat pump, and we’ll explain how it works here. Consider a heat pump for your next air conditioning installation, especially if you are located in the Atlanta area.

3 Reasons to Get a Heat Pump for Your AC Replacement in Atlanta

Monday, April 13th, 2015

You have a lot of options when it comes to replacing your older air conditioning system, one of which can both cool and heat a home efficiently and with just as much power as any other forced-air AC or heating system: the heat pump. Heat pumps are essentially air conditioners that can run in reverse. While conventional air conditioners only remove heat from the home and move it outside, heat pumps can move heat indoors as well. Here are 3 great reasons to consider these very effective units for your next AC (and heating) installation or replacement.

Heating Repair Question: Heat Pump Won’t Switch Modes

Monday, March 17th, 2014

Although heat pumps provide a number of excellent advantages as home comfort systems, such as energy-efficient performance and low emissions, the #1 benefit they offer is that they operate as both air conditioners and heaters. Two indoor comfort problems solved with one unit!

However, a heat pump can malfunction and become stuck in one mode, either blowing out heat when you want a cooled-down home, or blowing out chilled air when you want to warm up. When this happens, you lose one of the reasons you opted for heat pump installation in the first place. However, professionals can easily solve this problem and restore your heat pump to full power.

For help with cooling and heating repair in Atlanta, GA, call up the specialists who have delivered excellent comfort service since 1995: Air Conditioning Experts, Inc.

Why a heat pump won’t switch modes

The most common reason for a heat pump staying either in cooling or heating mode is a malfunction with the reversing valve. This valve is a crucial component that makes a heat pump different from a standard air conditioner: it sits on the refrigerant line and controls the direction the refrigerant flows through the unit. When the refrigerant changes direction, the heat pump switches from heating to cooling or vice versa. If the reversing valve breaks, the heat pump will remain in one mode (which one depends on the manufacturer’s settings). This is a simple repair for a professional: it only requires exchanging the broken reversing valve for a new one.

Another possibility for a heat pump that will only do half of its job is not a problem inside the heat pump, but in the thermostat. The electrical connections in the thermostat are responsible for signaling the heat pump to move from one mode to the other and to turn its blower on or off. If the thermostat loses that connection, the heat pump could remain fixed in one mode. Heating technician can trace down the source and repair the thermostat.

Heat pumps need trained repairs

Although you may feel tempted to open up the cabinet of your heat pump and tinker with the reversing valve, or unscrew the plate of your thermostat and fiddle with the wires, you are much more likely to cause further damage—unless you are a trained HVAC technician with the right equipment. It’s easy to find people who can do the work: call Air Conditioning Experts, Inc., any time of day or night, and we can take care of your cooling and heating repair in Atlanta, GA.

Heat Pump Only Blows Cold Air

Monday, March 3rd, 2014

When you have a heat pump installed, you expect it to perform two different jobs for you: send out warm air during cold weather, and send out cool air during hot weather. This dual function of heat pumps makes them popular options for home comfort, especially in Georgia where their powerful cooling mode makes them as effective as any standalone air conditioner.

But when a heat pump fails to live up to one part of its job—blowing out only cold air when you need warm air—you must call for repairs as soon as possible. Don’t wait and simply hope the heat pump will “warm up” eventually; they don’t work that way, and if a unit gets stuck in one mode, it likely means a malfunction that requires professional repairs.

When you need your heat pump in Atlanta, GA restored to full function, call Air Conditioning Experts, Inc. We have 24-hour emergency service for your convenience and comfort.

Why a Heat Pump May Blow Only Cold Air

A heat pump stuck in cooling mode probably has a failed reversing valve. This component serves to change the direction of the flow of refrigerant through the unit; when the refrigerant changes direction, the heat pump switches from heating to cooling mode or vice versa. If the reversing valve malfunctions, it will trap the heat pump in one mode or the other. A heat pump repair technician must open the cabinet, remove the broken reversing valve, and replace it with the correct unit.

Thermostat troubles constitute another possibility for the heat pump remaining in cooling mode. You should always check the thermostat’s setting when you encounter trouble regulating the temperature from a heat pump, since incorrect setting or programming can cause the system to switch into the wrong mode. A malfunctioning thermostat that loses its connection to the heat pump will also cause it to become stuck in one mode. Professionals can look over the thermostat to see if a malfunction has caused the problem.

Loss of refrigerant due to leaks can also impair the heat pump’s ability to provide warm air. Check the outdoor cabinet to see if you can spot ice developing over the coil. The presence of ice means a loss of refrigerant, and the outdoor coils will struggle to absorb the heat that the indoor coils will release. Scraping the ice off will do no good; you’ll need a technician to find and seal the leak, then recharge the refrigerant to its proper level.

Whatever the cause of the loss of heat in your heat pump in Atlanta, GA, a repair specialist from Air Conditioning Experts, Inc. will find out the trouble and know how to fix it. Put our combined 100 years of service experience to work for you.

Common Heat Pump Problems in Atlanta

Monday, January 28th, 2013

Heat pumps are renowned for their environmentally friendly heating and cooling performance as well as the incredible efficiency with which they operate. As is the case with any other heating and air conditioning system, of course, regular maintenance and a professional installation are necessary to ensure the high-quality, uninterrupted performance of your heat pump. You can get all the exceptional heat pump services you need in Atlanta simply by calling Air Conditioning Experts.

Of course any mechanical system is susceptible to wear and tear or damage. At some point you will need to schedule repair service for your heat pump. Here are some examples of the more common heat pump problems we face here in Atlanta.

  • Poor Temperature Maintenance – There are a lot of reasons why your heat pump may have trouble maintaining target temperatures, and they vary in degrees of seriousness. Sometimes it is as simple as incorrect settings at the thermostat. Anytime you are dealing with a system that both heats and cools it is possible to switch to the wrong function. This is definitely a best possible case scenario. There also may be a problem with your ductwork or the blower responsible for air dispersal.
  • Ice Building Up on Evaporator Coils – As with most heat pump problems, the development of ice on your evaporator coils can have many different causes. The most popular is insufficient refrigerant levels. This may indicate a leak, as refrigerant is recycled over and over in your heat pump system, not consumed, meaning levels should not really change. It is possible that some refrigerant was lost during service, but frequently frozen coils should certainly be inspected by a professional.
  • Cold or Hot Spots Developing – It is impossible to be really comfortable if different areas of your home are all different temperatures. Even heating is integral not only to comfort but to heating and cooling efficiency as well. This is most likely a ductwork problem, though a simple cause may be behind the uneven heating. Make sure that your furniture is not blocking air vents or registers. Your heat pump system will heat and cool your home a lot more effectively without having to force air through a sofa.

Occasional problems with your heating and cooling system are unavoidable. Keep them as infrequent as possible by scheduling high-quality, professional service. Call Air Conditioning Experts for all your heat pump needs in Atlanta.
