An air-source heat pump is the most common type of heat pump. It works by transferring heat between a house and the outdoors. Refrigerant travels in tubing between an outdoor compressor unit and indoor coils mounted on an air handler. Air-source systems require ductwork like what is used in a typical forced-air system.Everything You Need To Know About Heat Pumps

If your home lacks this type of ductwork, you’ll most likely look towards the mini-split heat pump system.

An entirely different heat pump system is the geothermal or ground-source or water-source heat pump. This type of heat pump transfers heat between the ground or a nearby water source to your home. Though it can be costly to install, it operates efficiently in areas with extreme climate changes, making it a viable option for homes here in Colorado.

Heat pumps are sophisticated appliances that can operate smoothly and efficiently for a long time. But like any other appliance, they can break down.

Heat Pump Doesn’t Operate
In some cases, your heat pump might not operate at all. Be sure the heat pump is receiving power. Check to make sure the heat pump condenser hasn’t tripped the circuits. You can also ensure the thermostat is set to the proper level and wasn’t accidentally changed. If you’ve had a new thermostat installed, be sure it is made for heat pumps, as the wrong one can be improperly wired and fry the internal electronics.

Doesn’t Heat or Cool Correctly.
Heat pumps don’t expel air that is as hot as you’ll experience with a gas-forced system. But if you’re certain it isn’t producing conditioned air, a little maintenance may be required. The heat pump filter may be dirty. The auxiliary heating elements may not be working properly. The outdoor condensing unit coils may be dirty or in need of repair.

Heat Pump Freezes Up
It isn’t unusual for a heat pump to ice up in really cold weather. When it happens, the defrost cycle should kick on to melt the ice. When that doesn’t happen, turn it off and make sure none of the return-air registers are blocked. Also, make sure the filter isn’t clogged. If there doesn’t seem to be a problem with the air flow, it’s time to call in an HVAC service professional.

Heat Pump Blower Doesn’t Work
This is caused by the thermostat or the limit switch located on the heat pump below the box that distributes heated air. Check to ensure the fan switch has been turned ON or on AUTO on your thermostat. The limit switch is designed to turn off the heat pump if the air around the box gets too hot.

Heat Pump Makes Noises
If the heat pump makes noises or rattles when it runs, be sure the cover panels are screwed tight. It may also be coming from rattling ductwork or loose parts in the air handler. If you can’t pinpoint where the problem is coming from, it may be time to call in an HVAC service technician for a routine maintenance call to ensure your system is operating properly.
