Air conditioners are one of the most integral parts of a home once the summer hits, which makes having an air conditioning troubleshooting guide so important. An AC unit can last for a number of years if it’s properly taken care of but sometimes unexpected issues arise that may be difficult to diagnose.

Spotting an issue and being able to take action to fix it is vital to preserving the lifespan of your AC. It also saves you time, energy and money, while also reducing the chances of needing to replace the unit.

Here are some common issues and suggested solutions to help keep you cool all summer long.

Air Conditioning Issues – Troubleshooting Guide

  • Issue: No cool air
    Solution: Generally, this is due to a lack of air flow. Make sure you have a clean filter in the unit to allow adequate cool air to blow through. If the filter has been replaced and you’re still having issues, contact ClimateCare to get further help sourcing the issue.
  • Issue: Strange noises
    Solution: Different noises can mean a variety of things. A banging noise can indicate a loose or broken part or that a part is out of balance. A clicking noise can be a sign of electrical issues. Any strange noise, such as humming, buzzing or rattling should be checked out by a technician.
  • Issue: Leaks
    Solution: This problem should be dealt with sooner than later by a trained technician. Leaks can lead to bigger, more costly problems and can be harmful to you, your family and the environment. Try to prevent the spread of leaks as best you can by laying down towels in the affected area until your technician arrives.
  • Issue: Automatic mode not working
    Solution: Start by looking at your thermostat as it may need new batteries. Old batteries can sometimes cause erratic operation. If that’s not the problem, it may be a relay or control board malfunction or electrical issue. Have it inspected by a technician. [1]
