Stuck in Defrost? Won't Switch Modes? Heat Pump Repair in Diablo, 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.
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.
Waiting rarely saves money and often turns a same-day repair into a longer, more involved job.
