Question 1

Why is my AC running but not cooling in Arizona?

Accepted Answer

The most common causes of an AC running but not cooling in Arizona are: dirty or clogged air filter, low refrigerant due to a leak, dirty condenser coils coated with dust or haboob debris, failed capacitor, undersized system, frozen evaporator coil, or a failing compressor. In extreme heat above 110°F, even a properly functioning system may struggle to keep up.

Question 2

How do I know if my AC has a refrigerant leak?

Accepted Answer

Signs of a refrigerant leak include ice forming on the refrigerant lines or evaporator coil, hissing sounds near the unit, warm air from vents despite the system running, and the system running longer than usual without reaching the set temperature. Refrigerant leaks require a licensed HVAC technician to diagnose and repair.

Question 3

What is a capacitor and how do I know if mine has failed?

Accepted Answer

Capacitors are small cylindrical components that start and run the compressor and fan motors. They are one of the most common failure points in Arizona — extreme heat degrades them faster than in cooler climates. Signs of a failed capacitor include the outdoor unit humming but not starting, the fan spinning slowly or not at all, or the system tripping the breaker repeatedly. Bradford technicians carry replacement capacitors on every service truck.

Question 4

Should I turn off my AC if it's not cooling?

Accepted Answer

If you notice ice forming on the refrigerant lines or the indoor unit, turn the system off and let it thaw for 2–4 hours before calling for service. Running a frozen system can damage the compressor. For all other 'running but not cooling' situations, you can leave the system running on fan-only mode while waiting for a technician to prevent the home from heating up further.
