Certified Heat Pump & Reversing Valve Specialists
Techs Who Actually Specialize in Heat Pumps

Stuck in Defrost? Won't Switch Modes? Heat Pump Repair in Covington, WA

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.

If you're dealing with 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, you already know 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.

Licensed Heat Pump Repair service in Covington, WA - AAA Pro HVAC

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.

Comprehensive Heat Pump Repair Solutions

From the first symptom to the final fix, these are the specific heat pump repair services our Covington-area crews are equipped for.

Reversing Valve Diagnosis & Repair

A stuck reversing valve is the single most common reason a heat pump gets stuck in one mode. This is one of the most requested heat pump repair calls we get across Covington, WA.

Defrost Cycle & Control Board Repair

We verify the defrost cycle actually triggers under test conditions. Techs handling defrost cycle & control board repair carry the specific parts and tools this job calls for, not a generic kit.

We test heat strip elements and the relay controlling them separately. This is one of the most requested heat pump repair calls we get across Covington, WA.

Common Heat Pump Repair Questions in Covington, WA

Why is my heat pump blowing cold air when it's set to heat?+

Often a stuck reversing valve, which controls whether the system is in heating or cooling mode.

Is ice on my heat pump's outdoor unit normal?+

If the unit stays iced for more than an hour, that's worth a service call.

How is heat pump repair different from regular AC repair?+

Heat pumps have a reversing valve, defrost cycle, and often auxiliary heat strips that standard AC systems don't have.

Why does my heat pump seem to run constantly in cold weather without ever feeling warm enough?+

If auxiliary heat isn't kicking in properly, that's a specific fault we can test for.

Do you repair ductless heat pump mini-splits?+

Yes — indoor head units and outdoor condensers on ductless heat pump systems are within our service scope.
