How often should my heat pump be maintained, and what does maintenance include?

To ensure optimal performance, your heat pump should be maintained at least once a year, though scheduling maintenance in both spring and fall is ideal for those using it for both heating and cooling. Done’s maintenance service includes cleaning or replacing the air filter, checking and adjusting the refrigerant levels, inspecting the electrical components and connections, cleaning the coils and fans, and ensuring the thermostat is accurately calibrated. Regular maintenance extends the lifespan of your heat pump, improves energy efficiency, and prevents costly breakdowns.
