We service both air-source and ductless heat pump systems.
A heat pump stuck in one mode, or one that's iced over and won't defrost, gets diagnosed with the right tools for that specific failure mode.
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.

Waiting rarely saves money and often turns a same-day repair into a longer, more involved job.
Our technicians treat every heat pump repair call in Como, WI the same way, whether it's a straightforward fix or a stubborn intermittent fault that two other companies already missed.
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.
Auxiliary heat strip diagnostics are included in the same visit when relevant.
We test reversing valve solenoids, defrost thermostats, and control board timing directly.
Every job starts with a real diagnosis, not a guess — here's the full scope of what our heat pump repair technicians handle across Como, WI.
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.
We verify the defrost cycle actually triggers under test conditions. Techs handling defrost cycle & control board repair carry the specific parts and tools this job calls for, not a generic kit.
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.
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 Como, WI.
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 Como, WI.
Indoor head unit and outdoor condenser are diagnosed as a connected system. This is one of the most requested heat pump repair calls we get across Como, WI.

That detail determines which specialized tools ride along.
We confirm your Como address and a realistic arrival window.
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.
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.

This is one of the most common and most misdiagnosed heat pump failures.
Some frost during a normal defrost cycle is expected; ice that never clears points to a defrost board or thermostat fault.
Heat pumps have a reversing valve, defrost cycle, and often auxiliary heat strips that standard AC systems don't have.
If auxiliary heat isn't kicking in properly, that's a specific fault we can test for.
These systems have their own fault-code patterns that our techs are trained to read.
