Heat pumps fail differently than standard AC or furnace systems, and diagnosing them requires understanding the reversing valve and defrost board specifically.
A heat pump stuck in one mode, or one that's iced over and won't defrost, gets diagnosed with the right tools for that specific failure mode.
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 Avoca, PA get treated with urgency, not a next-available-Tuesday slot.

Waiting rarely saves money and often turns a same-day repair into a longer, more involved job.
