A system running but not cooling almost always comes down to charge, airflow, or a failing component — we test all three.
Straightforward flat-rate pricing, quoted after diagnosis.
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.
We're licensed, insured, and staffed with techs who've spent years specifically on AC repair, not general handyman work with an HVAC certificate bolted on.

Every tech carries EPA Section 608 certification, required for legally handling refrigerant.
Trucks stocked and staged across Lohman, MO mean shorter windows than a call-center dispatch model.
Diagnostic first, quote second, work third — that order never changes.
Manifold gauges, digital thermometers, and airflow meters confirm the actual fault, not a guess.
From the first symptom to the final fix, these are the specific AC repair services our Lohman-area crews are equipped for.
Repeated low-charge calls on the same system usually mean an unrepaired leak from a prior visit elsewhere. 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 Lohman, MO.
We check for coil frost, which usually points to airflow or charge issues upstream. This is one of the most requested AC repair calls we get across Lohman, MO.
A failed compressor is often the last domino, not the first. This is one of the most requested AC repair calls we get across Lohman, MO.
We verify the low-voltage circuit before assuming the outdoor unit is at fault. Techs handling thermostat calibration & wiring carry the specific parts and tools this job calls for, not a generic kit.
Error codes on the wall unit display get cross-referenced against the manufacturer's chart. 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.
Workmanship is backed in writing on your invoice.

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.
They caught it before the compressor overheated and swapped the fan motor same visit.
Mini-split in the sunroom was throwing a code I couldn't find online.

Usually low refrigerant charge from an undetected leak, a dirty evaporator coil, or restricted airflow from a clogged filter.
Ice almost always means something is restricting airflow or refrigerant flow, and running it iced up can damage the compressor.
Adding refrigerant without finding the leak just means another service call later.
We carry recovery equipment rated for legacy refrigerants.
Yes — indoor head units, outdoor condensers, and line sets all fall under our service scope.
We prioritize no-cool calls with vulnerable occupants when scheduling.

Our AC repair crews are positioned throughout Lohman, MO to keep response times realistic, not just promised.
