Common AC Problems & How to Troubleshoot Them
Before calling for professional AC repair service, homeowners can try a few simple troubleshooting steps for common problems. These basic checks might save you time and money if the issue is something you can fix yourself. If these steps don't work, it's best to contact a professional to prevent further damage.
- AC blowing warm air - Check if your thermostat is set to "cool" mode and at the right temperature; replace dirty air filters; make sure the outdoor unit isn't covered with debris or vegetation
- Strange noises (banging, grinding, whistling) - Turn off the system immediately; check for loose panels or debris; clean or replace air filters; inspect visible fan blades for obstructions
- Water leaking around indoor unit - Check if drain line is clogged or disconnected; clean air filter if dirty; make sure unit is level; check if condensate pump is working (if you have one)
- System cycling on and off frequently - Clean or replace air filters; remove debris from around the outdoor unit; check thermostat placement (away from heat sources); make sure return air vents aren't blocked
- Weak airflow - Check and open all supply vents; replace dirty air filters; examine ductwork for visible damage; make sure the outdoor unit is clean and free from obstruction
- Unusual odors - Replace air filters; check for mold in ductwork or drain pan; consider professional duct cleaning if smell persists
