At SumZero Energy Systems, our Heat Pump Repair begins with a thorough diagnostic to pinpoint the root cause of problems like no heat or cooling, short cycling, icing on the outdoor unit, weak airflow, unusual noises, thermostat inaccuracies, refrigerant leaks, tripped breakers, reversing valve faults, and worn capacitors, contactors, or blower motors.
