Common San Diego HVAC Problems We Fix
San Diego's coastal climate creates unique HVAC challenges. Salt air corrodes coils and electrical connections, marine-layer humidity strains evaporator coils, and inland dust clogs filters faster than in drier regions.
Our technicians commonly repair:
- Refrigerant leaks from corroded coil fittings or vibration damage
- Blower motors clogged with coastal dust and marine particulates
- Thermostat malfunctions causing short cycling or uneven temperatures
- Capacitor and contactor failures common in aging systems
- Dirty evaporator and condenser coils reducing cooling output
Repair or Replacement: What Does My System Need?
Repair is usually right when your system is under 10-12 years old and the fix is straightforward. Replacement makes more sense when repair costs approach half the price of a new unit or when the system fails repeatedly. Signs you likely need repair now: weak airflow, grinding or rattling noises, warm air from vents, and rising utility bills. Our technicians give an honest assessment with no pressure.
