7 DIY Air Conditioner Troubleshooting Tips

House graphic with icons illustrating the DIY AC troubleshooting tips

When your air conditioner stops working, it’s easy to assume the worst. Your first instinct is to call your HVAC technician to come and fix whatever is broken – and fast. But not every AC malfunction needs to result in a service call. In fact, some problems have simple DIY solutions that can save you money and restore your home comfort in a snap.

Before you make that call for emergency AC repair service, here are 7 troubleshooting steps you can take.

  1. Set your unit to cool. Sometimes an accidental bump of the thermostat could switch your unit into the off position.
  2. A dirty air filter can block the airflow to your unit, leading to a shutdown. Consult your manual, and change your filter in the recommended intervals (usually once every 1-3 months).
  3. Clean and unblock your supply and return vents to protect your unit and to ensure that your unit is receiving proper airflow.
  4. Sometimes an unexpected AC shutdown can be the result of a simple breaker trip. Check your fuse box!
  5. Holes or gaps in your ductwork can leak air. Examine your attic and crawlspace if you are having problems.
  6. In the small grey box outside (called the AC disconnect box), check to see if the disconnect switch is in the on position. If it is in the off position, reset it, but be mindful of potential voltage hazards!
  7. A build-up of leaves or grass clippings around your outdoor unit could interrupt your service. Keep it clean!

So, next time your air conditioner fails, don’t panic! One of the above tips could be the only solution you need to get your system up and running again.
