HVAC Maintenance & Tune-Up in San Diego County, CA


Signs Your AC Needs Repair
• Warm or weak airflow — Low refrigerant, a failing compressor, or a dirty coil.
• AC won't turn on — Thermostat, capacitor, tripped breaker, or control-board fault.
• Strange noises — Grinding, squealing, or banging signal a failing motor, loose part, or compressor issue.
• Runs constantly, never cools — Common on inland OC homes during heat waves.
• Corrosion on the outdoor unit — Coastal OC condensers take salt-air damage; rust and fin damage cut performance.
• Water or refrigerant leaks — Pooling water or oily residue needs prompt attention.
