Common AC Problems During Temecula Summers

Temecula's intense summer heat pushes air conditioning systems to their limits. Our service calls increase dramatically during heat waves as systems struggle to keep up. Understanding common problems helps you respond appropriately.

Refrigerant Leaks

Low refrigerant causes your AC to blow warm air and run constantly without cooling effectively. Unlike fuel, refrigerant doesn't get "used up." Low levels indicate a leak that needs professional repair.

Frozen Evaporator Coils

Ironically, your AC can freeze even in 100-degree weather. Restricted airflow or low refrigerant causes coils to ice over. Turn off the system to let ice melt, then call for service.

Capacitor Failure

Capacitors help start and run the compressor and fan motors. Extreme heat accelerates wear. A failed capacitor prevents your system from starting or causes it to shut down unexpectedly.

Dirty Condenser Coils

Your outdoor unit releases heat into the air. When condenser coils become coated with dirt and debris, heat transfer suffers. The system works harder and cooling decreases.

Thermostat Issues

Sometimes the AC works fine but the thermostat malfunctions. Before assuming major problems, check thermostat settings and batteries. A faulty thermostat can mimic system failure.

Clogged Drain Lines

AC systems remove humidity, producing condensation that drains away. Algae and debris can clog drain lines, causing water backup and potential damage.

Compressor Problems

The compressor is the heart of your system. Compressor failure is expensive to repair. Often, replacement of the entire outdoor unit or system makes more economic sense.

Prevention Is Key

Many summer breakdowns result from deferred maintenance. Annual tune-ups identify developing problems before they cause failures. Schedule service before summer heat arrives.
