How To Troubleshoot Common Heat Pump Problems

Heat pumps are a whole-home heating and cooling solution that is often more energy efficient than central heating and air. However, a heat pump will require occasional maintenance and repair like any other appliance. Here is an explanation of common heat pump problems and the possible causes behind them.

Reduced Airflow

Even if your heat pump is heating or cooling air to the correct temperature, it will not be of much use if it is not circulating enough air through your home. Reduced airflow can occur due to a number of different causes. The problem may be as simple as poor maintenance by the homeowner. If the heat pump filter is not cleaned or replaced at least once a month, it can become clogged with dirt and choke off airflow to your system.

If your heat pump filter is clean, the reduced airflow may be caused by a problem with the blower motor. The blower motor can begin to malfunction due to dust buildup inside the heat pump or simply from year of regular use. Contacting an HVAC technician for a professional inspection is the best way to determine if the blower motor is not running at full capacity.

Only the Fan Is Running

If your heat pump is stuck in fan-only mode, you will notice that the air that comes out of the vents in your home is cool or lukewarm no matter how you set the thermostat. To confirm that only the fan is working, you can turn your system on and walk out to the outdoor condenser unit to see if you can hear it running.

A heat pump that is stuck in fan-only mode could be caused by something as simple as a malfunctioning thermostat. The condenser will not run if the thermostat cannot send the signal for it to turn on. Alternatively, the problem may lie with the power supply to your condenser. You should check your breaker box to see if the breaker to the condenser has tripped. If this is not the case, it is possible that there is a wiring problem in the condenser's circuit that will require professional repair.

Maintaining and troubleshooting a heat pump is not a difficult task if you know about the common problems that can occur and a few simple fixes. Keep these tips in mind so you can avoid being left without heat or air due to a malfunctioning heat pump. Contact a company like A One Heating & Air Conditioning for more information.
