What kind of maintenance does a heat pump need?

To ensure top performance, heat pumps must be serviced on a regular basis. Air filters must be inspected and replaced every 1-3 months, trash from outdoor units removed, and proper airflow around the unit assured. To avoid efficiency loss, clean the coils once a year and have an expert check the refrigerant levels. In addition to these tasks, electrical connections must be inspected, the thermostat calibrated, and moving parts maintained. Professional maintenance services include a complete check to identify potential issues and keep the heat pump functioning efficiently.

How do heat pumps work?

Heat pumps work by transferring heat from one location to another using refrigerant. In heating mode, the pump extracts heat from outdoor air and transfers it indoors. In cooling mode, it removes heat from indoor air and releases it outside. A compressor pressurizes the refrigerant, increasing its temperature. As the refrigerant flows through coils, it absorbs or releases heat, depending on the mode. The cycle repeats to maintain desired indoor temperatures. Heat pumps offer energy-efficient heating and cooling, making them popular in moderate climates.
