About Airsun
A family business,
building trust one home at a time.
Airsun was started by a Southern California family tired of watching neighbors get overcharged and under-served by big-box HVAC brands. Today we run the same way we started — small, honest, and personally invested in every home we walk into.
What we stand for
Four rules. No exceptions.
Family first
We answer the phone the way we'd want someone to answer ours.
Honest work
Upfront pricing. No surprise fees. If we don't recommend it for our own home, we won't recommend it for yours.
Craftsmanship
Neat linesets, sealed ducts, level pads. Every install is one you'd be proud to show off.
Community
We live here, our kids go to school here, and we're not going anywhere.
Credentials
Licensed. Insured. Local.
- California Contractor's License#1142130 — verifiable with the CSLB.
- Fully insured & bondedLiability and workers' comp on every job.
- Serving OC + the Inland EmpireAnaheim, Irvine, Santa Ana, Riverside, Corona, Ontario, Fontana, Rancho Cucamonga and beyond.
Our promise
If we don't recommend it for our own home, we won't recommend it for yours.
Every homeowner deserves the same fair shake we'd want. That means a real diagnosis, a written quote, honest options, and a clean worksite when we leave. Nothing more, nothing less.
Written quotes, always
You see the price before we lift a wrench. No verbal 'about a…' pricing.
Uniformed technicians
Marked trucks, ID badges, and a name you'll recognize on the driveway.
Fully insured every visit
Liability and workers' comp on every job — protection for your home and our crew.
Show up when we say
If we're running late, you get a text with a real ETA — not radio silence.
Right-sized systems
We run a real load calc. No oversized units that short cycle and cost you more.
Bilingual & respectful
English or Español, shoes off if you'd like, and every question answered.
How we work
A visit with Airsun, start to finish.
Here's what to expect from the first phone call to the follow-up text — no surprises, no runaround.
You call, we answer
A real person picks up — usually within a few rings — and gets the basics so we can help fast.
We show up on time
You get a technician name and ETA before we roll up. If we're delayed, you'll know.
Diagnose & explain
Photos, readings, and plain-English options. You choose — we don't pressure.
Do the work right
Clean install, tidy worksite, full walkthrough, and a follow-up to make sure it's still working.
