AC Problems We See Most During Valley Summers

When valley temperatures climb past 110°F, air conditioners work overtime. Systems that seemed fine in spring suddenly struggle. Here's what we see most often.

Refrigerant Running Low

Low refrigerant means your system can't transfer heat properly. You'll notice warm air from vents and ice forming on lines. Refrigerant doesn't get used up—low levels mean a leak exists.

Frozen Coils

Sounds strange during heat waves, but evaporator coils freeze when airflow restricts or refrigerant runs low. The system runs but cooling stops. Shut it down and let ice melt before calling for service.

Dead Capacitors

Capacitors help motors start and run. Valley heat accelerates their failure. A bad capacitor might cause the system not to start, or to shut down unexpectedly after running.

Dirty Condenser Coils

Your outdoor unit releases heat into the air. Coated with dirt and dust, heat transfer drops dramatically. The system works harder and cooling suffers.

Thermostat Confusion

Sometimes everything except the thermostat works fine. Check settings and batteries before assuming major problems. Bad thermostats create symptoms mimicking serious failures.

Clogged Condensate Drains

Air conditioning removes humidity, creating water that drains away. Blocked drains cause backups, water damage, and system shutdown from safety switches.

Compressor Failure

Compressor problems are expensive. When compressors fail in older systems, replacement of the entire outdoor unit often makes more economic sense than repair.

Prevention Beats Repair

Most summer breakdowns connect to deferred maintenance. Annual tune-ups identify problems before they strand you in the heat. Schedule service before summer arrives.
