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.

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?+

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?+

A technician needs specific training on these components to diagnose heat pump issues accurately.

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.
