Hello to all Im new here and I hop im doing this right.
I have a 1991 Heil heat pump. when it is in cooling mode the compressor unit (outside unit) comes on and works well for about 10 min. then shuts off for about 35min. like something is getting hot.Cools down and does the same thing
never comes on and stay on until the thremostat it cool enough the indoor temp is 90deg and the temp is set at 78deg
last year it worked fine what went wrong this past winter. HVAC guy i talked to said he has no idea what could be wrong and didnt even offer to come and look. If anyone has any Ideas I would sure Thankyou. Rick
