Common heat pump repair needs


While an electric heat pump is a significant investment, it handles the duties of both a heating and cooling system.

Having one unit manage year round temperature control saves on space, maintenance requirements and running costs.

However, the system is covering two workloads and operating just about year round. While heat pumps are known for their reliability, there is the potential for malfunction. Even a small refrigerant leak can negatively impact the efficiency of operation and lead to diminished heating or cooling capacity. Reduced airflow, hissing sounds and ice buildup on the coils are signs of a refrigerant leak. The issue needs to be resolved by a licensed HVAC professional. They have the skills, tools and qualifications necessary to identify and repair the leak, replace problematic components and recharge the system. Electrical concerns can cause frequent tripping of circuit breakers, irregular operation and a thermostat that doesn’t respond to adjustment. Loose electrical connections, a faulty compressor or difficulties with wiring can be the reason. Another common concern is frozen evaporator coils. A dirty air filter, low refrigerant levels or restricted airflow can lead to the evaporator coils freezing. The heat pump might blow warm air in cooling mode or quit working altogether. If turning off the system and allowing the coils to defrost and checking for obstructions to airflow doesn’t solve the problem, it’s best to contact a licensed HVAC technician for heat pump service. If the heat pump makes a grinding, banging or squealing noise, the cause might be the blower fan, compressor or other internal components. To restore safe and proper operation, it’s always recommended to contact a qualified HVAC contractor for repairs.
