What Should I Do If My AC Is Running But Not Cooling?

Start with a few quick checks. If cooling doesn’t return, schedule professional troubleshooting. Our technicians inspect filters, coils, refrigerant levels, drains, thermostats, and wiring on all makes and models.

• Set thermostat to Cool and lower the setpoint.
• Replace or clean the air filter.
• Clear debris from the outdoor unit and coils.
• Check the breaker and equipment power switch.
• Look for ice on refrigerant lines or water near the air handler.
