About Heat Pump Repair

Heating or cooling problems, diagnosed and fixed

Heat pumps work year-round, so they can fail in either season. Common symptoms include cold air in heating mode, ice on the outdoor unit, a system that runs constantly and strange noises or smells.

We diagnose the issue, explain what we find and repair it. If a replacement makes more sense, we explain that honestly too.

Questions About Heat Pump Repair

Still have a question?

Call 615-357-7797

Why is my heat pump blowing cold air in winter?

Possible causes include a defrost cycle, a stuck reversing valve, low refrigerant or a control issue. A proper diagnosis finds the cause.

Is ice on my heat pump normal?

A thin layer of frost that clears during defrost is normal. Thick ice that stays is a sign something is wrong and should be checked.

Should I repair or replace an older heat pump?

Age, the repair cost and refrigerant type all matter. Our Repair or Replace Advisor gives a quick view, and we give you a straight answer on site.
