Besides annual servicing, where a professional checks the entire system, you can do the following to maintain your GSHP:

• Check the filters. If your system has filters, they’ll need cleaning several times a year to ensure good airflow

• Inspect the ductwork. If your system uses ductwork, ensure it’s clean and well-sealed for maximum efficiency

• Clean indoor and outdoor units. Ensure no debris or objects obstruct the units

• Check the thermostat. Make sure the thermostat is working properly and that it’s set to the right temperature

Some maintenance will need to be done by a professional, such as checking the ground loops, but this will all be covered during an annual service.

You can do some aspects of heat pump maintenance yourself, but others will need to be done by a professional.
