Which type of maintenance is essential for air-to-air heat pumps?

Conducting regular filter changes and coil cleaning is vital for maintaining air-to-air heat pumps because these components directly impact the efficiency and effectiveness of the system. Filters trap dust, dirt, and other airborne particles, preventing them from entering the heat pump. When filters become clogged, airflow is restricted, leading to decreased performance, increased energy consumption, and potential damage.

Regularly cleaning the coils is also crucial since dirty coils can hinder the heat transfer process. If the coils are not clean, the heat pump must work harder, which can lead to higher utility bills and a shortened lifespan of the unit. By focusing on routine maintenance of filters and coils, homeowners can ensure their heat pumps operate efficiently and reliably over time.
