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

Certified Heat Pump Repair Across Lone Tree, IA

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.

Before You Call: Heat Pump Repair Answers

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?+

Heat pumps naturally work harder as outdoor temperatures drop, and auxiliary heat should engage below a certain threshold.

Do you repair ductless heat pump mini-splits?+

These systems have their own fault-code patterns that our techs are trained to read.

How fast can a heat pump specialist reach Lone Tree during winter?+
