We carry R-410A and R-22 service equipment so we're not turning away older systems.
A tech who explains superheat and subcooling readings instead of just saying 'it's low on freon'.
If you're dealing with warm air blowing from the vents, ice forming on the copper line, or a condenser fan that's stopped spinning outside, you already know a system that's technically running but not actually cooling the house is one of the most misdiagnosed HVAC complaints there is.

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.
AAA Pro HVAC built its AC repair process around one idea: diagnose first, quote honestly, fix it right.
Every truck across Walnut Creek, CA carries the tools and common parts specific to AC repair, so most calls finish in a single visit.

We recover, don't vent — it's the law and it's how we protect your system's warranty.
We route by real-time technician location, not a fixed territory list.
Diagnostic first, quote second, work third — that order never changes.
We check superheat and subcooling against manufacturer spec before touching the refrigerant charge.
From the first symptom to the final fix, these are the specific AC repair services our Walnut Creek-area crews are equipped for.
Low charge is a symptom, not a diagnosis — we find the leak with electronic detection and UV dye before recharging. Techs handling refrigerant charge & leak repair carry the specific parts and tools this job calls for, not a generic kit.
We test motor amperage against rated draw before replacing. This is one of the most requested AC repair calls we get across Walnut Creek, CA.
A dirty or frosted evaporator coil restricts airflow and drops cooling capacity fast. Techs handling evaporator coil cleaning & repair carry the specific parts and tools this job calls for, not a generic kit.
A failed compressor is often the last domino, not the first. Techs handling compressor diagnostics carry the specific parts and tools this job calls for, not a generic kit.
We verify the low-voltage circuit before assuming the outdoor unit is at fault. This is one of the most requested AC repair calls we get across Walnut Creek, CA.
Ductless systems fail differently than central air — we service indoor head units, line sets, and outdoor condensers. Techs handling ductless mini-split diagnostics carry the specific parts and tools this job calls for, not a generic kit.

Tell us whether the air is warm, the unit is icing, or it's not running at all — that detail changes what parts ride along.
Techs arrive with manifold gauges and common capacitor/contactor stock already loaded.
Superheat, subcounting, and airflow readings get taken before any refrigerant is added.
Most refrigerant and component repairs wrap same-visit.

Turned out to be a slow leak at the schrader valve — they found it with dye, fixed it, and recharged properly.
Outdoor unit had ice forming on the copper line which I'd never seen before.
Condenser fan had completely stopped and the compressor was still trying to run.
Their tech knew it on sight and had a replacement part on the truck.

Usually low refrigerant charge from an undetected leak, a dirty evaporator coil, or restricted airflow from a clogged filter.
Turn the system off, set the fan to run, and call — running a frozen coil makes the underlying problem worse.
Adding refrigerant without finding the leak just means another service call later.
We carry recovery equipment rated for legacy refrigerants.
