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.
Our technicians treat every heat pump repair call in Denmark, WI the same way, whether it's a straightforward fix or a stubborn intermittent fault that two other companies already missed.
Every truck across Denmark, WI carries the tools and common parts specific to heat pump repair, so most calls finish in a single visit.

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.
Auxiliary heat strip diagnostics are included in the same visit when relevant.
Refrigerant charge is verified against heat pump-specific specs, which differ from standard AC charging.
From the first symptom to the final fix, these are the specific heat pump repair services our Denmark-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 Denmark, WI.
We verify the defrost cycle actually triggers under test conditions. This is one of the most requested heat pump repair calls we get across Denmark, WI.
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 Denmark, WI.
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.
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.

Describe whether the system is stuck in one mode, iced over, or not heating/cooling at all.
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.
Workmanship is guaranteed and documented on your invoice.

System would only blow cold air no matter what mode I selected.
Outdoor unit was constantly covered in ice and I thought that meant it was broken.
Auxiliary heat strips weren't kicking in during a cold snap and the house couldn't keep up.
Tech recognized it immediately as a defrost-related fault specific to that brand.

Often a stuck reversing valve, which controls whether the system is in heating or cooling mode.
Some frost during a normal defrost cycle is expected; ice that never clears points to a defrost board or thermostat fault.
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.
These systems have their own fault-code patterns that our techs are trained to read.
No-heat heat pump calls get year-round priority dispatch across Denmark, WI.

Whether you're in the heart of Denmark or one of the surrounding communities, dispatch routes the closest available technician.
