We service both air-source and ductless heat pump systems.
Auxiliary heat strip issues are checked alongside the heat pump itself.
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.

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.
AAA Pro HVAC built its heat pump repair process around one idea: diagnose first, quote honestly, fix it right.
We're licensed, insured, and staffed with techs who've spent years specifically on heat pump repair, not general handyman work with an HVAC certificate bolted on.

Our techs are specifically trained on reversing valves, defrost boards, and auxiliary heat systems, not just general AC repair logic.
Heat pumps run in both summer and winter, so we treat heat pump failures as urgent regardless of season.
You get a quoted price after the reversing valve and defrost cycle are actually tested, not billed for trial-and-error.
We test reversing valve solenoids, defrost thermostats, and control board timing directly.
From the first symptom to the final fix, these are the specific heat pump repair services our Comfort-area crews are equipped for.
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 Comfort, TX.
An outdoor unit that ices over and never defrosts usually points to a failed defrost thermostat or control board timing issue. This is one of the most requested heat pump repair calls we get across Comfort, TX.
We test heat strip elements and the relay controlling them separately. Techs handling auxiliary / emergency heat strip repair carry the specific parts and tools this job calls for, not a generic kit.
We charge to the manufacturer's heat pump-specific target, not a generic number. This is one of the most requested heat pump repair calls we get across Comfort, TX.
We distinguish between the two before recommending any repair. Techs handling outdoor unit icing diagnostics carry the specific parts and tools this job calls for, not a generic kit.
Indoor head unit and outdoor condenser are diagnosed as a connected system. Techs handling ductless heat pump system repair carry the specific parts and tools this job calls for, not a generic kit.

That detail determines which specialized tools ride along.
Heat pump-trained technicians arrive with reversing valve and defrost diagnostic equipment already loaded.
Reversing valve, defrost cycle, and refrigerant charge are tested against heat pump-specific specs before any quote.
Most reversing valve and defrost board repairs finish same-visit with parts carried on the truck.

Previous company just topped off refrigerant twice — this tech found the stuck reversing valve in ten minutes.
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.

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.
A technician needs specific training on these components to diagnose heat pump issues accurately.
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.
