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 Waynesville, NC get treated with urgency, not a next-available-Tuesday slot.

Previous company just topped off refrigerant twice — this tech found the stuck reversing valve in ten minutes.
Outdoor unit was constantly covered in ice and I thought that meant it was broken.
They tested the relay separately from the strips themselves and found the actual fault fast.
Tech recognized it immediately as a defrost-related fault specific to that brand.

This is one of the most common and most misdiagnosed heat pump failures.
If the unit stays iced for more than an hour, that's worth a service call.
Heat pumps have a reversing valve, defrost cycle, and often auxiliary heat strips that standard AC systems don't have.
