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

Stuck in Defrost? Won't Switch Modes? Heat Pump Repair in Tarzana, CA

Heat pumps fail differently than standard AC or furnace systems, and diagnosing them requires understanding the reversing valve and defrost board specifically.

Auxiliary heat strip issues are checked alongside the heat pump itself.

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, which is exactly why heat pump repair calls in Tarzana, CA get treated with urgency, not a next-available-Tuesday slot.

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?+

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?+

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.
