AC Repair San Antonio — Same-Day Service.
When your AC goes out, you're not calling a call center — you're calling me. I've been doing this 28+ years and I trained my three sons — Jonathan, Josh, and Benjamin — right alongside me. We treat your home like our own, and we'll give you honesty every time.

I'm Clint — if you're not ready to schedule yet but want straight answers, just text me. No pressure, no follow-up calls.
"I started Carnes and Sons because I was tired of watching big companies overcharge families for simple repairs. I trained my boys — Jonathan, Josh, and Benjamin — the same way: show up, be honest, fix it right. When we show up at your door, we're not trying to sell you something. If a $50 part fixes it, that's what we'll tell you. Period."
— Clint Carnes, Founder & Dad
