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 Eaton, OH get treated with urgency, not a next-available-Tuesday slot.

Most heat pump repair problems give some warning before they turn into a system stuck blowing cold air in heating mode, an outdoor unit that's iced over and won't run its defrost cycle, or a system that switches modes but never actually reaches set temperature — catching it early usually means a shorter, cheaper fix.

System would only blow cold air no matter what mode I selected.
Turned out the defrost thermostat had failed, so it never actually triggered the defrost cycle.
They tested the relay separately from the strips themselves and found the actual fault fast.
Ductless heat pump in the addition threw a code I couldn't find anywhere online.

Often a stuck reversing valve, which controls whether the system is in heating or cooling mode.
If the unit stays iced for more than an hour, that's worth a service call.
