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?+

If the unit stays iced for more than an hour, that's worth a service call.

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?+

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

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