Hi, I'm Jeremy from Airworx Heating and Air Conditioning out of Salt Lake City, Utah, and today I would like to talk to you about what it looks like and what are the effects of your air conditioning coil being froze up. One good recognizable area that you can look at is your air conditioning lines. Your air conditioning lines will typically have light frost on them. If they do have white frost on them, then what you'll want to do is you want to shut your system down, down here at the switch, and it'll allow that system to thaw out. If that system's thawed out, it's a very good idea to be able to call a qualified technician to be able to help you troubleshoot that. Your furnace filter that's on the inside of there, if it has not been changed out, you'll want to change that first, and then call your qualified technician after you have thawed your air conditioning coil out completely. Once again, I'm Jeremy from Airworx Heating and Air Conditioning out of Salt Lake City, Utah, and we just talked about frozen coils.
