When an AC unit stops working, a homeowner should first check for simple issues before calling a professional. Common problems include a tripped circuit breaker, a dirty air filter, or a blocked outdoor unit. If these simple steps do not resolve the issue, a professional is required to diagnose and repair the fault.
DIY AC troubleshooting guide
Follow these steps before calling a professional:
- Check the Circuit Breaker: Go to your fuse box and check if the breaker for the AC unit has tripped. Simply reset it if it has.
- Clean the Filter: A dirty air filter can restrict airflow and cause the unit to shut down.
- Inspect the Outdoor Unit: Ensure the unit is not blocked by debris or plants, which can restrict airflow.
- Listen for Sounds: If you hear an unusual buzzing or humming, it may indicate a serious problem.
