Why is My AC Not Cooling?

Action Air has some troubleshooting tips for you to try if you turn down your thermostat and the air conditioner is still not cooling

Check your thermostat

  • Make sure it is set to “cool.”
  • Check to make sure someone hasn’t changed the temperature setting.

Check your air filter

  • Turn the system off, remove the filter, and inspect.

Check your vents

  • If cool air is blowing from some registers but not from others, there’s a good chance the ducting that feeds the registers is at fault.
  • If this is the case, you’ll need to call Action Air to check your ductwork.

Check the outdoor unit

  • Clean away all debris or anything else that might be crowding the unit, such as overgrown vine.
  • Make sure nothing has been placed on top of the unit which might be blocking the fan.

Damaged heat pump

  • In some cases, it could be the heat pump. Things like a clogged coil, frozen coil, refrigerant leaks, compressor malfunctions, etc. could be the problem. These things need to be checked by the professionals at Action Air.

Undersized air conditioner

  • Air conditioners are “sized” according to the amount of cooling they can provide. You might not notice any problems with an undersized unit until the outside temperature rises and the unit has to work overtime to cool your home.
