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.

Our Full Range of Heat Pump Repair Services

From the first symptom to the final fix, these are the specific heat pump repair services our Marengo-area crews are equipped for.

A stuck reversing valve is the single most common reason a heat pump gets stuck in one mode. This is one of the most requested heat pump repair calls we get across Marengo, IL.

An outdoor unit that ices over and never defrosts usually points to a failed defrost thermostat or control board timing issue. This is one of the most requested heat pump repair calls we get across Marengo, IL.
