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

Stuck in Defrost? Won't Switch Modes? Heat Pump Repair in Norman, OK

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.

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

Heat pumps run in both summer and winter, so we treat heat pump failures as urgent regardless of season.

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.

Comprehensive Heat Pump Repair Solutions

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

Reversing Valve Diagnosis & Repair

We test the valve's solenoid directly rather than assuming based on symptoms alone. This is one of the most requested heat pump repair calls we get across Norman, OK.

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 Norman, OK.

Auxiliary / Emergency Heat Strip Repair

Backup electric heat strips that fail can leave a home without adequate heat during the coldest stretches. Techs handling auxiliary / emergency heat strip repair carry the specific parts and tools this job calls for, not a generic kit.

Refrigerant Charge & Leak Detection

Outdoor Unit Icing Diagnostics

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.

Before You Call: Heat Pump Repair Answers

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?+

Heat pumps naturally work harder as outdoor temperatures drop, and auxiliary heat should engage below a certain threshold.

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.

How fast can a heat pump specialist reach Norman during winter?+
