Techs Who Actually Specialize in Heat Pumps

Stuck in Defrost? Won't Switch Modes? Heat Pump Repair in London, 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.

Professional Heat Pump Repair technician working in London, CA

Heat Pump Specialization

Our techs are specifically trained on reversing valves, defrost boards, and auxiliary heat systems, not just general AC repair logic.

Year-Round Priority Dispatch

Heat pumps run in both summer and winter, so we treat heat pump failures as urgent regardless of season.

Flat-Rate Pricing, No Guesswork Billing

You get a quoted price after the reversing valve and defrost cycle are actually tested, not billed for trial-and-error.

Specialized Diagnostic Tools

We test reversing valve solenoids, defrost thermostats, and control board timing directly.

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 London-area crews are equipped for.

Reversing Valve Diagnosis & Repair

We test the valve's solenoid directly rather than assuming based on symptoms alone. 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 London, CA.

Auxiliary / Emergency Heat Strip Repair

We test heat strip elements and the relay controlling them separately. This is one of the most requested heat pump repair calls we get across London, 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 London, CA.

Outdoor Unit Icing Diagnostics

We distinguish between the two before recommending any repair. This is one of the most requested heat pump repair calls we get across London, CA.

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 London, CA.

Common Heat Pump Repair Questions in London, 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?+

Some frost during a normal defrost cycle is expected; ice that never clears points to a defrost board or thermostat fault.

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?+

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?+

These systems have their own fault-code patterns that our techs are trained to read.

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