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

Signs Your AC Needs Repair

Your air conditioner will usually show warning signs before completely breaking down. Recognizing these signals early can save you money and prevent uncomfortable days without cooling. If you notice any of these symptoms, it's time to call for professional AC repair service.

  • Unusual noises - Grinding, squealing, or banging sounds indicate mechanical problems
  • Weak airflow - Air that barely comes out of vents suggests fan or duct issues
  • Warm air - If your system blows warm air despite being set to cool, you may have refrigerant leaks
  • Strange odors - Musty smells can indicate mold growth, while burning odors suggest electrical problems
  • High energy bills - Sudden increases in electricity costs often mean your system is working inefficiently
  • Frequent cycling - AC turning on and off repeatedly without cooling your home properly
  • Water leaks - Pooling water around indoor unit signals drainage problems
  • Ice formation - Frozen coils or refrigerant lines indicate serious system issues
  • Humidity problems - Your home feeling sticky despite the AC running suggests cooling issues

I'm not one to post many reviews or voice something publicly. But I will recommend this company 10 out of 10 to everyone. The owner is a man with heart and passion that loves even the little man, and their tech's work shows it. Kevin was my tech and was probably the nicest person I've ever had the pleasure of meeting. These guys are your guys for the job.
