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

Heat Pump Repair in Saint Paul, MNFrom Techs Who Know the Reversing Valve

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.

Common Heat Pump Repair Questions in Saint Paul, MN

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?+
