We pull diagnostic codes, check refrigerant pressures, and test the circuit board before we ever quote you a fix.
No overtime surcharges, no runaround.
If you're dealing with a compressor that hums but won't start, a blower motor that's seized, or a control board that's throwing an error code you can't decode, you already know the exact hour your system fails is never convenient — it's usually the hottest afternoon or the coldest night of the month.

Most HVAC repair problems give some warning before they turn into a compressor that hums but won't start, a blower motor that's seized, or a control board that's throwing an error code you can't decode — catching it early usually means a shorter, cheaper fix.
AAA Pro HVAC built its HVAC repair process around one idea: diagnose first, quote honestly, fix it right.
We're licensed, insured, and staffed with techs who've spent years specifically on HVAC repair, not general handyman work with an HVAC certificate bolted on.

Our crews are background-checked, bonded, and trained on both gas and electric systems.
We stage trucks throughout Shandon, CA so a tech is rarely more than an hour out.
Our pricing book covers parts and labor together so the number you approve is the number you pay.
Manifold gauges, combustion analyzers, and amp clamps ride in every van, not just the big jobs.
From the first symptom to the final fix, these are the specific HVAC repair services our Shandon-area crews are equipped for.
We test start capacitors and windings before recommending a full swap, since not every hard-start symptom means a new compressor. Techs handling compressor diagnostics & replacement carry the specific parts and tools this job calls for, not a generic kit.
We test capacitance against the rated microfarad value rather than replacing parts on a hunch. Techs handling capacitor & contactor repair carry the specific parts and tools this job calls for, not a generic kit.
Topping off refrigerant without finding the leak just delays the same failure. Techs handling refrigerant leak detection carry the specific parts and tools this job calls for, not a generic kit.
A blower that hums but doesn't spin, or one that's pulling excess amperage, gets tested under load, not just visually inspected. Techs handling blower motor & fan repair carry the specific parts and tools this job calls for, not a generic kit.
Modern systems throw fault codes for a reason — we read them, cross-reference the manufacturer's service chart, and confirm the fault before replacing a board. Techs handling circuit board & control diagnostics carry the specific parts and tools this job calls for, not a generic kit.
We check low-voltage wiring runs end to end before assuming the thermostat is the culprit. Techs handling thermostat & wiring troubleshooting carry the specific parts and tools this job calls for, not a generic kit.

Describe the symptom — no cool, no heat, strange noise, tripped breaker — and dispatch routes the nearest available tech.
Your technician arrives in a stocked van, not an empty one.
Full diagnostic pass — electrical, refrigerant, airflow — before a single number gets quoted.
Every repair is backed by our workmanship guarantee, detailed in your final paperwork.

Compressor wouldn't kick on during a heat wave and the tech had it diagnosed — bad start capacitor — inside twenty minutes.
System was short-cycling every few minutes and two other companies just wanted to sell me a new unit.
Blower motor was pulling way more amps than it should and starting to smell hot.
Their tech pulled up the manufacturer's fault chart on his phone and had it sorted in under an hour.

Most 'no warning' failures actually had small symptoms beforehand, like short cycling or a faint hum, that got missed.
We'll give you an honest read on remaining lifespan and repair cost versus a new install quote, not a sales pitch either direction.
Our vans stock the capacitors, contactors, igniters, and control boards behind most common failures.
Call dispatch directly for a live estimate on arrival time.
Diagnostic time is built into the quote, not billed separately.
Emergency dispatch pricing is disclosed on the call, before a truck rolls, so there's no surprise on the invoice.

Our HVAC repair crews are positioned throughout Shandon, CA to keep response times realistic, not just promised.
