6 Reasons Why Your Air Conditioning Might Not Work

These are the most common problems. We can help.

It's no fun when temperatures climb to near 100 degrees and your air conditioning system isn't functioning properly. Here are the top 6 causes:


  1. LEAKING REFRIGERANT. Leaks are commonly found around the hose connections to the A/C unit. It's difficult to pinpoint on your own, but we have the equipment & expertise to get it done;
  2. CONDENSER IS BLOCKED. The condenser is designed to re-cool hot refrigerant once it has been condensed using the airflow that comes through the front of your car as you drive. If the condenser is blocked by debris, it will not operate properly. The A/C unit will only expel hot air. The condenser is typically located at the front of the vehicle. Visually inspect it to see if anything is blocking it or the grill and safely remove the debris.
  3. CONDENSER IS BROKEN. Condensers sometimes break after being punctured from road debris going through the grill of your vehicle and damaging the equipment causing failure. If you notice any punctures, your condenser will need to be replaced;
  4. ELECTRICAL ISSUES. These are the most difficult to diagnose and you'll need Hometown for this. This would be an A/C unit that has completely stopped working, sometimes caused by broken or frayed wiring. Call to schedule an appointment 614-895-8069;
  5. FAULTY COOLING FANS. Over time, your vehicle will emit only hot air. Visually inspect your fan for breakage. Cracks in the fans are caused by road debris and replacement is the best course of action. Other common issues are blown fuses and electrical issues. These will require professional service from a qualified mechanic;
  6. THE COMPRESSOR HAS FAILED. Without a functioning compressor, the refrigerant cannot circulate through the system and you will not get cold air. The most common reason for failure for the compressor going bad is periods of long time without use. Lack of use tends to shock the system when it is finally used again after being dormant throughout the winter. Make sure that you use the a/c system on full blast for 15 minutes every 3 weeks or so regardless of the outdoor temperature.
