We service both air-source and ductless heat pump systems.

A heat pump stuck in one mode, or one that's iced over and won't defrost, gets diagnosed with the right tools for that specific failure mode.

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.

Comprehensive Heat Pump Repair Solutions

Every job starts with a real diagnosis, not a guess — here's the full scope of what our heat pump repair technicians handle across Castaic, CA.

Reversing Valve Diagnosis & Repair

A stuck reversing valve is the single most common reason a heat pump gets stuck in one mode. Techs handling reversing valve diagnosis & repair carry the specific parts and tools this job calls for, not a generic kit.

Defrost Cycle & Control Board Repair

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 Castaic, CA.

Auxiliary / Emergency Heat Strip Repair

Backup electric heat strips that fail can leave a home without adequate heat during the coldest stretches. This is one of the most requested heat pump repair calls we get across Castaic, CA.

Refrigerant Charge & Leak Detection

Heat pump refrigerant charging follows different specs than standard AC systems, especially across heating and cooling modes. This is one of the most requested heat pump repair calls we get across Castaic, CA.

Outdoor Unit Icing Diagnostics

We distinguish between the two before recommending any repair. Techs handling outdoor unit icing diagnostics carry the specific parts and tools this job calls for, not a generic kit.

Ductless Heat Pump System Repair

Ductless mini-split heat pumps have their own fault-code language separate from central systems. This is one of the most requested heat pump repair calls we get across Castaic, CA.

Common Heat Pump Repair Questions in Castaic, CA

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?+

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.
