Stuck in Defrost? Won't Switch Modes? Heat Pump Repair in Deerfield, IL

Name: AAA Pro HVAC
Telephone: +1-866-805-8548
Price range: $$
Rating: 4.9

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.

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?+

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.
