You say the return air measured 62 and that the supplys measured 72-79 are you sure your not stating this backwards. Normally when you are in the a/c mode the supply air measures 15 - 20 degrees colder then the return air ?. You didnt state if you have gas or electric I have seen a sequencer stick and the air conditioning and part of the heat operate at the same time
