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.

Low charge is a symptom, not a diagnosis — we find the leak with electronic detection and UV dye before recharging. This is one of the most requested AC repair calls we get across Llano, TX.
A condenser fan that's stalled or running slow lets head pressure spike, which can trip the compressor's high-pressure safety. This is one of the most requested AC repair calls we get across Llano, TX.
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 Llano, TX.

House was sitting at 84 degrees and the vents were blowing lukewarm air.
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.

A full diagnostic checks all three before we touch the refrigerant charge.
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.
