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?+

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?+

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?+

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 Flagtown during winter?+
