Everyone enjoys the warmth of summer, but your car AC not working can turn a warm day unbearably hot very quickly. Your Pataskala, OH, Ford dealership can fix your AC for you. These are a few signs that your AC needs some help.
Noises From the AC
Your AC should make almost no noise. You’ll hear a slight clink now and again as the compressor switches on and off. You’ll also hear the sound of the cold air rushing in if you have the speed turned high enough. If you hear rattling, rustling, or clunking noises, this means there’s a problem in your AC that our technicians need to investigate.
Rustling noises could be caused by leaves and other debris that have blown into the AC system and are moving around. The rattling or clunking noise could be caused by damaged parts of the AC, for example, worn compressor bearings. Our technicians will check your AC and find and fix the problem.
Moldy Smells
When you turn on the AC for the first time in summer, you expect gusts of cold air. You don’t expect that cold air to carry moldy smells with it. A damp, earthy smell, when the AC is running, is a sign that bacteria or mold have taken up residence in your AC system. This usually happens in winter since the AC isn’t being used. The lack of air movement allows bacteria or mold to grow undisturbed.
These organisms smell bad, and they can cause allergic reactions or illness. Our technicians can fix this problem by pumping a strong anti-bacterial and anti-mold cleaning solution into the AC system. We’ll turn on the AC, and the solution will spread through the AC. Once the solution has done its work, your AC will be fresh and clean.
AC Blows Cold, Then Hot Air
If your AC blows cold air and then suddenly blows stifling hot air, your AC system has a problem. The most likely cause of this issue is a blocked or damaged expansion valve in the evaporator. The evaporator is the part of your AC that removes heat and humidity from the cabin. The expansion valve controls the flow of refrigerant into the system.
Refrigerant is the gas that chills the air that blows from the AC. Over time, this small valve can become partially blocked. As your AC works, the restricted opening can result in the expansion valve freezing. This completely blocks the flow of refrigerant, and the heat and humidity will blow back into your cabin. We’ll unblock or replace this valve to fix the problem.
