Question about Heating & Cooling
Frost is caused by the refrigerant pressure being too low on the low pressure side of the system. That is, the compressor has more ability than the cold coil is using up. This can be caused by insufficient air flow over the cold coil or a shortage of refrigerant.
Insufficient air flow can be caused by a dirty coil, filter, or blower wheel, or collapsed ducts, to name a few. It is most likely that some of the refrigerant has escaped and the leak needs to be repaired and the refrigerant topped up to the right amount. You'll need to use the proper gauges, a good thermometer, and read the chart that is glued inside the access door on the condenser, or...check for any available repairs that are free because of your warranty.
I did know of a Sears 5,000 BTU window air that was simply designed wrong, but that was many many years ago.
