We service both air-source and ductless heat pump systems.
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 Clayton, DE 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.

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.
Heat pumps naturally work harder as outdoor temperatures drop, and auxiliary heat should engage below a certain threshold.
Yes — indoor head units and outdoor condensers on ductless heat pump systems are within our service scope.
