Expert heat pump repair across Los Angeles.
Heat pumps fail differently than traditional AC units — reversing valves, defrost boards, refrigerant circuits that run year-round. Our technicians understand the difference and diagnose them accurately the first visit.
Heat pump repair in Los Angeles — the right diagnosis
A heat pump that's blowing cold air in heating mode, making a clicking sound on startup, or running constantly without reaching setpoint isn't just "broken" — each symptom points to a specific component. HVAC in LA is led by a USC-trained mechanical engineer who trained on refrigerant-cycle diagnosis, not parts-swapping.
We service all heat pump types: single-stage, two-stage, variable-speed, cold-climate systems, and ductless mini-split heat pumps from all major brands.
Common heat pump problems we fix
- Heat pump blowing cold in heat mode — reversing valve failure, low refrigerant, defrost issue
- System stuck in one mode — reversing valve solenoid, thermostat wiring, control board
- Short cycling — refrigerant charge, oversized system, thermostat placement
- Not defrosting — defrost board, outdoor sensor, refrigerant pressure
- Loud noises — fan motor, compressor, refrigerant slugging
- High electricity bills — degraded COP, refrigerant leak, airflow restriction
