TOP 5 CAUSES OF FROZEN AC COILS 5. Frozen AC coils are caused by refrigerant leaks. Refrigerant is the chemical that runs through your AC coil, changing pressure and temperature in order to absorb heat. If it leaks, the lack of pressure will make it absorb more heat than it should. This makes the MOLD IN AIR DUCTS? HOW IT GOT THERE & HOW TO GET RID OF IT Slow water leaks might not be noticeable right away, but over time they create an ideal breeding ground for mold in air ducts, and also water damage in your space. Use a dehumidifier in a very humid environment, such as an indoor pool room or basement space. A dehumidifier can help keep the air dry enough to prevent mold. WHAT CAUSES CONDENSATION ON AN AC VENT? Let’s go over how moisture can get on your AC vent, and the potential damage it can do. Then we’ll explain the possible causes. It’s important to check them out, because the water on your AC vent might be condensation, but it also might be coming from your ducts or your air conditioner itself.
