The answer to 'how to maintain a heat pump' is to perform regular maintenance and cleaning to keep it running efficiently. This includes cleaning the outdoor unit, changing air filters, and scheduling professional tune-ups. Proper maintenance can extend the life of your heat pump and help it operate at peak performance.
Start by cleaning the outdoor unit at least once a year, preferably in the spring before heavy use. Use a garden hose to gently spray away any dirt, leaves, or debris that has accumulated on the coils and fins. Avoid using a pressure washer, as this can damage the delicate components. Next, check and replace the air filters every 1-3 months, depending on usage and indoor air quality. Dirty filters restrict airflow and reduce efficiency. Finally, have a professional HVAC technician inspect and service your heat pump annually to ensure all components are working properly and to identify any potential issues before they become major problems.
