How Can I Reset My AC When It Is Not Cooling Properly?

Turn the system off at the thermostat, wait a few minutes, then turn it back to Cool and Auto. If the unit still isn’t cooling, do a simple reset and basic checks before calling for service in Phoenix or Scottsdale.

Quick reset and checks:

• Set thermostat to Off; wait a few minutes.
• Replace a clogged air filter.
• Check the AC breaker and outdoor disconnect.
• Clear debris around the outdoor unit.
• If you see ice on the lines or coil, leave system Off to thaw, then restart.
