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.

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

Auxiliary heat strip diagnostics are included in the same visit when relevant.

Specialized Diagnostic Tools

Refrigerant charge is verified against heat pump-specific specs, which differ from standard AC charging.

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 Fontana-area crews are equipped for.

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 Fontana, 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 Fontana, 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 Fontana, CA.

Refrigerant Charge & Leak Detection

We charge to the manufacturer's heat pump-specific target, not a generic number. Techs handling refrigerant charge & leak detection carry the specific parts and tools this job calls for, not a generic kit.

Outdoor Unit Icing Diagnostics

Some icing is normal during defrost cycling; persistent icing that never clears points to a genuine fault. This is one of the most requested heat pump repair calls we get across Fontana, 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 Fontana, CA.

Common Heat Pump Repair Questions in Fontana, 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?+

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 Fontana during winter?+
