Why is My Air Conditioner Not Working?

Air conditioning Ann Arbor

Is your air conditioner only blowing hot air?

Does your AC unit not power on?

Are you getting some cool air but finding that your house is still too warm?

If you suspect that something’s wrong with your AC, we have a few DIY checks for you! Beat the heat and stay cool in Ann Arbor this summer! Make sure to handle all your AC components carefully to avoid hurting yourself or damaging the equipment—if the repairs are too complicated for you, don’t hesitate to call a professional!

Here are some DIY troubleshooting tips for a broken air conditioner unit:

  1. Make Sure Power is Connected – Check your main electrical panel to make sure the unit has power running to it. See if any of the breakers have tripped. If they have, reset them. If your breakers are being tripped regularly, it could be a sign of problems with other components!
  2. Double Check Your Thermostat – It might sound obvious, but make sure your thermostat is on and set 5-10 degrees cooler than the current temperature in your home. If nothing is showing on the display, check the batteries!
  3. Check Filter and Outdoor Blockage – Check that the air filter is clean by holding it up to a light. You should be able to see light through it! If your filter isn’t dirty, check the vents on your outside unit for debris or blockage that could be restricting air flow.
  4. Ice Buildup – Ice on the copper refrigerant lines or outside of your AC unit might be the result of a refrigerant leak, low refrigerant levels, faulty parts, or restricted airflow. Check to see if the fan spins, your filter is clean, and that airflow isn’t blocked. If nothing looks visibly damaged, turn the power off to let the ice thaw and try your AC afterwards. If that doesn’t work, leave the power off and call a technician —something inside your unit might have to be replaced!
