Rating: 4.9

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.

Professional Heat Pump Repair technician working in Williston, ND

Heat Pump Specialization

Our techs are specifically trained on reversing valves, defrost boards, and auxiliary heat systems, not just general AC repair logic.

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.

We test reversing valve solenoids, defrost thermostats, and control board timing directly.

Heat Pump Repair Done Right, Every Time

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

Reversing Valve Diagnosis & Repair

A stuck reversing valve is the single most common reason a heat pump gets stuck in one mode. 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 Williston, ND.

Auxiliary / Emergency Heat Strip Repair

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.

Refrigerant Charge & Leak Detection

Heat pump refrigerant charging follows different specs than standard AC systems, especially across heating and cooling modes. This is one of the most requested heat pump repair calls we get across Williston, ND.

Outdoor Unit Icing Diagnostics

Some icing is normal during defrost cycling; persistent icing that never clears points to a genuine fault. This is one of the most requested heat pump repair calls we get across Williston, ND.

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.

Heat Pump Repair FAQ

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

This is one of the most common and most misdiagnosed heat pump failures.

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?+

These systems have their own fault-code patterns that our techs are trained to read.

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

No-heat heat pump calls get year-round priority dispatch across Williston, ND.
