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

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

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

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.

Licensed Heat Pump Repair service in San Francisco, CA - AAA Pro HVAC

Most heat pump repair problems give some warning before they turn into 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 — catching it early usually means a shorter, cheaper fix.

Heat Pump Repair Done Right, Every Time

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

Reversing Valve Diagnosis & Repair

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 San Francisco, CA.

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 San Francisco, 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 San Francisco, CA.

Refrigerant Charge & Leak Detection

We charge to the manufacturer's heat pump-specific target, not a generic number. This is one of the most requested heat pump repair calls we get across San Francisco, CA.

Outdoor Unit Icing Diagnostics

Some icing is normal during defrost cycling; persistent icing that never clears points to a genuine fault. 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 San Francisco, CA.

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?+

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.

Do you repair ductless heat pump mini-splits?+

Yes — indoor head units and outdoor condensers on ductless heat pump systems are within our service scope.

How fast can a heat pump specialist reach San Francisco during winter?+
