Many modern heat pumps provide homes with both heating and cooling. When something goes wrong, you need to determine the cause of the problem and fix it immediately to ensure your family’s comfort. The trusted HVAC contractors at ABLE Heat & Cool in Troy, MO, have shared a few of the most common heat pump issues.

3 Common Heat Pump Issues

1. Frozen Unit

Heat Pumps are designed for cold weather, so they will automatically defrost when a thin layer of ice builds up on their sides. However, if the ice gets too thick without being removed, it stops the pump from working properly by blocking the heat transfer between the refrigerant and the exterior air. If you find this layer of ice on your unit, it could be the result of a few problems, such as a faulty fan motor, low refrigerant, defrost circuit board or related controls. Keep snow from piling up around the unit and don’t try to chip away the ice, as you can damage the system. Calling an HVAC contractor to determine the cause of the problem may be the best option.

2. Constant Running

If it seems like your heat pump is constantly running, you should check that your thermostat is set properly.  If this isn’t the issue and extreme outdoor temperatures don’t explain the constant running, you could have low refrigerant or control issues with the auxiliary heat in the furnace or air handler.

3. Cold Air in Heat Mode

If your pump is blowing cold air while it is set to heat mode, check that it is not covered with a layer of ice. If this is not the issue, then it could be a problem with a valve, compressor, the refrigerant charge or a number of control problems. A professional HVAC contractor can fix the problem and ensure the heat pump works properly year-round.
