Good evening all, This morning woke up to my home freezing cold i'd left the ac on 72, cut it off allowed home to naturally warm up by the afternoon it was getting hot again so turned air back on and set it for 75, went to the store came back about an hour later to my house being very warm checked ac and it was blowing out warm air, cut it off and back on and let it run for a while still warm air. now it 3 hours later and air is blowing cool once again no frost on any of the lines everything looks as it normally does does anyone know what would cause it to work intermittingly??
