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 Sun Prairie, MT - AAA Pro HVAC

Professional Heat Pump Repair technician working in Sun Prairie, MT

Heat Pump Specialization

Heat pump failure modes are different enough from standard AC that generic diagnostics often miss the actual cause.

Year-Round Priority Dispatch

No-heat calls in winter get the same priority as no-cool calls in summer.

Flat-Rate Pricing, No Guesswork Billing

You get a quoted price after the reversing valve and defrost cycle are actually tested, not billed for trial-and-error.

Specialized Diagnostic Tools

Refrigerant charge is verified against heat pump-specific specs, which differ from standard AC charging.

Our Full Range of Heat Pump Repair Services

Every job starts with a real diagnosis, not a guess — here's the full scope of what our heat pump repair technicians handle across Sun Prairie, MT.

Reversing Valve Diagnosis & Repair

We test the valve's solenoid directly rather than assuming based on symptoms alone. Techs handling reversing valve diagnosis & repair carry the specific parts and tools this job calls for, not a generic kit.

Defrost Cycle & Control Board Repair

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 Sun Prairie, MT.

Auxiliary / Emergency Heat Strip Repair

Backup electric heat strips that fail can leave a home without adequate heat during the coldest stretches. This is one of the most requested heat pump repair calls we get across Sun Prairie, MT.

Refrigerant Charge & Leak Detection

We charge to the manufacturer's heat pump-specific target, not a generic number. Techs handling refrigerant charge & leak detection carry the specific parts and tools this job calls for, not a generic kit.

Outdoor Unit Icing Diagnostics

Some icing is normal during defrost cycling; persistent icing that never clears points to a genuine fault. Techs handling outdoor unit icing diagnostics carry the specific parts and tools this job calls for, not a generic kit.

Ductless Heat Pump System Repair

Ductless mini-split heat pumps have their own fault-code language separate from central systems. Techs handling ductless heat pump system repair carry the specific parts and tools this job calls for, not a generic kit.
