Troubleshooting Tips for Common Air Conditioning Repairs

There’s nothing worse than having a failed A/C unit on a hot summer day. Fortunately, there are a few ways to quickly troubleshoot your air conditioning. With these tips and tricks, your A/C unit will up and running in no time.

Three DIY Tricks

There are three way to find out what’s wrong with your AC unit, that anyone can do.

  1. Check the main electrical panel – The main electrical panel in your home is like the brain of your AC unit. Chances are if there’s a problem with your AC unit, it can be solved by just looking at the main panel and checking for a tripped breaker or a blown fuse. If your fuse is broken, you can reset it by turning it on and off. If it still doesn’t work, then you might have to replace the fuse.
  2. Remove the thermostat cover – Do this after you’ve tuned off the power to the air conditioner. After removing the cover, remove the thermostat from its base and replace the batteries. When you remount the thermostat, make sure all wires are properly attached to their terminals. Then, replace the cover, and wait at least 5 minutes before turning the system back on.
  3. Check the compressor’s capacitor and wires – The capacitor in the compression fixture is what starts the condenser and the fan. If your capacitor is broken, your A/C unit will not run. To fix it, turn off all the power to the unit, remove its cover, and use a digital meter to set to it to ‘Capacitance.’ Put one lead on the common terminal and the other lead on one of the other two terminals. The meter should show a number, not ‘OL.’
