My Air Conditioner Isn’t Cooling!

Posted on

One of the most common summertime complaints we hear is people whose air conditioners just stop cooling. But before you call an HVAC company, there is a whole list of things you can check that could save you a lot of time, money, and headaches:

What to Look for When Your AC Isn’t Cooling

  • Make sure the switch on your thermostat is set to cool and that the temperature is set below the current temperature.
  • Make sure the power to your unit is on! Check the electrical connections to your indoor and outdoor units, both at the units themselves and at the breakers.
  • If the power is on, check and see if the outdoor unit is actually running. If not, look for a big red RESET button on the unit and push it.
  • If this doesn’t work, look inside for a condensate pump near your indoor unit. There may be a safety switch near the pump designed to cut power to the outdoor unit if the pump overfills. Make sure the pump is working.
  • If you’re still having problems, go back outside and find the disconnect box mounted on the wall. If the connection here is cut (either because of a tripped breaker, a flipped switch, or a blown fuse), you can try to reconnect it. Note: air conditioners deal in high voltage and the risk of electrocution is high. Don’t attempt to work with the disconnect switch unless you’re familiar with working with electricity.

What to Do If Your AC Is Running but not Cooling

If both the indoor and outdoor units of your air conditioner are running but your home still isn’t cooling down, there could be a number of things wrong. Some of these things you can try to fix on your own, others you’ll need to call an HVAC company to help with:
