Well, the real problem starts inside on your indoor coil. This coil will be a solid block of ice and this area that you see here will be completely encrusted with ice, oftentimes an iceberg, sometimes two or three feet high.

And until that ice is melted you can’t get any air through the cooling coil. So the big mistake when you have a frozen unit is you turn it off and you turn it back on in an hour and it just starts icing up again. What you have to do when an air conditioner ices up is it has to thaw.

One of the biggest issues that we have with frozen units is people call for help and they think that if they leave the air conditioner running they’re gonna have cooling while they’re waiting for us to get there. That’s not true. If you can’t get air across the cooling coil you’re not going to have any cooling.

As a matter of fact you can burn up your air conditioner to leave it running with ice on it. So you need to call your contractor and regardless of how uncomfortable you are turn it off. And you need to wait at least four or five hours to have them come out. Because if they get there and there’s any ice left on this coil there’s not a thing they can do technician’s usually gonna charge you a service call turn around and leave and tell you he’ll be back the next day. Many, many times people say they turned it off and they don’t and they’re very unhappy because we can tell.
