AC TROUBLESHOOTING TIPS 

Looking to fix an AC issue on your own? Be sure to look over the provided air conditioning troubleshooting tips. 

No Air Blowing in the House, AC Not Running Outside

  • Verify that your thermostat is set to cool, and the set point is below the room temperature.

  • Check to confirm that the furnace or air handler is plugged in.

  • Check the circuit breaker. This is typically marked FURNACE, Heater or AH on the breaker panel cover (check power by plugging a hair dryer into the same outlet).

  • Replace the thermostat’s batteries.

No Air Blowing in the House, AC Is Running Outside

 

  • Check your air filter. A dirty air filter may indicate you have a frozen evaporator.

  • If the filter is clean and the furnace can be heard running indoors, check for closed registers. Insufficient air flow will freeze a coil.

  • Be on the lookout for signs of ice at the copper lines outdoors and indoors.

  • Turn the system to OFF and put the fan in the ON position for 1.5 to 2 hours to defrost the coil. Turn it back and hopefully you will have air while you await our arrival, at which point we can test the rest of the system.

  • Be prepared for water resulting from melting ice.

Air is blowing in house, AC is not running outside

 

  • ​Check your fuses and/or circuit breaker. This is typically marked “AC.”

  • You can have fuses checked at a local hardware store. Wait for a technician if you do not know where to find your fuses.

  • Take safety precautions around electricity and turn circuit breakers off before testing fuses.

  • Watch for water leaks around the furnace.

  • Check your air filter. A dirty filter may cause the evaporator to freeze (see above concerning freeze up).

  • Possibilities include a plugged condensate drain. A worst-case scenario may involve a rusted out evaporator (typically after 10 years of use).
