My indoor coil has a block of ice on it during the summer and my unit is not functioning. Whats wrong?
There are a few possible problems. The two most commom causes are a dirty air filter and/or insufficient freon. The first thing you should do is turn your system off at the thermostat and place the fan in the on position to let the hot air from the house defrost the ice slowly and then call for service. If your filter is very dirty and you suspect that is the problem, you can turn your system off for about two hours (allow sufficient time for the ice on the coil to melt) and put in a clean filter. Once the ice has completely mel ted , you can try restarting the unit. If the problem recurs you should call for service. Keep in mind that ice melting will become water so take precautions to soak up the water in order to prevent any water damage.
