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

Year-Round Heat Pump Repair Across Sullivan, IL

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.

Heat Pump Repair FAQ

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?+

Some frost during a normal defrost cycle is expected; ice that never clears points to a defrost board or thermostat fault.

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?+

If auxiliary heat isn't kicking in properly, that's a specific fault we can test for.

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 Sullivan during winter?+
