The Difference
Quick fixes break twice.
Proper diagnosis holds.
Most HVAC failures we see started with someone else's shortcut. A refrigerant top-off instead of a leak repair, an oversized unit instead of a load calc, a fast install instead of a clean one. We work the opposite direction.
Explain it clearly.
You'll see what's failing, why it's failing, and the real options to fix it. Written estimate, no upsell theater.
Install it to last.
Brazed joints, proper evacuation, correct charge, sealed plenum. Done the way Carrier engineered it.
Stand behind it.
Workmanship guarantee plus full manufacturer warranty. If we touched it and it breaks, we come back.

Honest Answers
Questions worth asking out loud.
Pulled from the calls we get most often. If yours isn't here, call us. We'll answer it directly.
Ask a real techQ / 01Do you charge a diagnostic fee?
We charge a flat trip & diagnostic that's waived if you proceed with the repair the same visit. No surprise add-ons, no per-hour creep. You'll know the number before we open the truck.
Q / 02How fast can you actually get out here?
Average dispatch is around 2 hours in the San Antonio metro. Same-day is the default; after-hours and weekends are scheduled on request, not a separate "emergency" line that costs triple.
Q / 03Should I repair my old unit or replace it?
Depends on age, refrigerant type, repair cost vs. system value, and whether it's been installed correctly. We'll walk you through both math problems on-site, not over the phone, and not before we've looked at it.
Q / 04Do you handle property management work orders?
Yes. Volume discounts, dedicated point-of-contact, tenant-friendly scheduling, and digital invoicing. We currently service multiple management companies across San Antonio.
Q / 05What brands do you install?
We're a Carrier Factory Authorized Dealer, that's our specialty. We also install and service Trane, Lennox, Rheem, Goodman, Bryant, Daikin, Mitsubishi (mini-split), and most major manufacturers.
Q / 06Is financing available?
Yes. We offer promotional financing, with approved credit, on qualified system replacements, plus longer-term plans. We'll also handle the paperwork on any active CPS Energy or Carrier rebates you're eligible for.
