Heat pumps fail differently than standard AC or furnace systems, and diagnosing them requires understanding the reversing valve and defrost board specifically.
Auxiliary heat strip issues are checked alongside the heat pump itself.
A heat pump that seems to be 'not heating' is often actually a reversing valve or defrost cycle problem, which a technician trained mainly on standard ac systems can easily misdiagnose, which is exactly why heat pump repair calls in Jonesville, KY get treated with urgency, not a next-available-Tuesday slot.
