Licensed Ac Repair service in San Dimas, CA - AAA Pro HVAC

Most AC repair problems give some warning before they turn into warm air blowing from the vents, ice forming on the copper line, or a condenser fan that's stopped spinning outside — catching it early usually means a shorter, cheaper fix.

Ac Repair Done Right, Every Time

From the first symptom to the final fix, these are the specific AC repair services our San Dimas-area crews are equipped for.

Refrigerant Charge & Leak Repair

Repeated low-charge calls on the same system usually mean an unrepaired leak from a prior visit elsewhere. This is one of the most requested AC repair calls we get across San Dimas, CA.

Condenser Fan Motor Repair

We test motor amperage against rated draw before replacing. Techs handling condenser fan motor repair carry the specific parts and tools this job calls for, not a generic kit.

Evaporator Coil Cleaning & Repair

A dirty or frosted evaporator coil restricts airflow and drops cooling capacity fast. This is one of the most requested AC repair calls we get across San Dimas, CA.

A failed compressor is often the last domino, not the first. This is one of the most requested AC repair calls we get across San Dimas, CA.

Ac Repair FAQ

Why is my AC running but not actually cooling the house?+

Usually low refrigerant charge from an undetected leak, a dirty evaporator coil, or restricted airflow from a clogged filter.

Is ice on my AC unit a serious problem?+

Ice almost always means something is restricting airflow or refrigerant flow, and running it iced up can damage the compressor.

How much refrigerant does my system actually need?+

Adding refrigerant without finding the leak just means another service call later.

Can you service older R-22 systems?+

We carry recovery equipment rated for legacy refrigerants.

Do you work on ductless mini-split systems?+

Yes — indoor head units, outdoor condensers, and line sets all fall under our service scope.

How fast can someone reach San Dimas during peak summer demand?+

We prioritize no-cool calls with vulnerable occupants when scheduling.
