From a one-truck Glendora startup to the SGV’s go-to HVAC team.
Canyon Air Systems opened its doors in Glendora in 1979, and for forty-five years we’ve done one thing: residential and light-commercial HVAC for the San Gabriel Valley. Same trade. Same town. Same standards.
Today we run a fleet of fully-stocked vans, a roster of factory-trained technicians, and 10,000+ systems serviced across the SGV, LA Basin, Inland Empire, and north Orange County. We answer the phone with a human, we quote in writing before we start work, and we call to follow up after every install. Not because it’s a script — because it’s the only way to still be in business after this long.
We’re a locally-owned business that happens to do enterprise-grade HVAC. That’s the whole pitch.
The values that haven’t changed in 45 years.
Honesty over upsell.
We tell you what your system actually needs — not what would help us hit a quota. If a $40 capacitor fixes it, we don’t pitch a new condenser.
On time, every time.
You get a real arrival window, not an 8-hour block. If we’re running late, we call — before the window ends, every time, no exceptions.
Clean shoe covers, every visit.
Our techs cover their shoes at the front door, lay drop cloths in work areas, and leave your home cleaner than they found it. Always.
