Air source heat pump repair covers the most common type of residential heat pump system in the United States. These systems extract heat from outdoor air to warm your home in winter and reverse the process for cooling in summer, making them an efficient all-in-one HVAC solution.
How This System Works
Air source heat pumps are the most widely installed residential heat pump type, accounting for over 80% of heat pump installations. Unlike geothermal systems that use ground loops or pool heat pumps designed for water heating, air source units rely on an outdoor fan to draw air across the evaporator coils.
Common Air Source Heat Pump Repair Problems
Defrost Cycle Problems
During cold weather, frost builds up on the outdoor coils. The defrost cycle should melt this frost periodically. When the defrost cycle malfunctions, ice can completely encase the outdoor unit, requiring air source heat pump repair for the defrost control board, sensor, or reversing valve.
Refrigerant Leaks
Air source systems are susceptible to refrigerant leaks at connection points, coil joints, and the service valves. Symptoms include reduced heating and cooling, ice on refrigerant lines, and higher energy bills. Leak repair and recharge costs $200-$800.
Outdoor Fan Motor Failure
The outdoor fan motor runs whenever the heat pump is operating. These motors can fail due to bearing wear, capacitor failure, or electrical issues. A failed fan motor causes the system to overheat and shut down. Replacement costs $300-$700.
Auxiliary Heat Issues
Most air source heat pumps include electric resistance backup heat for extremely cold days. If the auxiliary heat strips fail, you may notice the system cannot maintain temperature during cold snaps.
