Precision Air Inc has completed tens of thousands of work orders across San Diego County. Each one tested our skill, our honesty and our follow-through.
No contractor gets every job perfect. Across that many work orders, a part sometimes fails early, a problem comes back, or a visit doesn't go the way it should. When that happens, we don't disappear. We come back, find the cause and make it right. That's the real test of a contractor, and it's the one we work hardest to pass.
Still here to make it right.
A guarantee is only as good as the company behind it. A young company may do good work, but it hasn't been around long enough to show it will still be in business when something fails years from now. We've been here since 2014, and we stand behind our work.
Our workmanship is guaranteed. Every installation includes our standard 1-year labor warranty, extended warranties are available, and your equipment also carries the manufacturer's warranty.
Our license number tells a story.
The California Contractors State License Board (CSLB) issues license numbers in order: lower numbers were issued earlier, higher numbers are newer. Ours is CSLB #996275, starting with 99.
Recently issued licenses start with a 1. A license that new may belong to a young company that's still proving itself. It can also mean a business changed hands or changed the person responsible for the license, even if the name on the truck looks familiar.
Before you hire any contractor, including us, look them up on the CSLB license lookup. It takes a minute and shows how long they've been licensed and whether there are any complaints or actions against them.

Family-owned, built from the ground up.
Stephen Diefenderfer founded Precision Air Inc from scratch. He started as a technician and has held every position in the company since, so he knows what each job takes because he's done it.
We're locally owned. We live, shop and hire here, and the community we serve is our own. With no outside investors and no private-equity owners, the money our work brings in stays in San Diego County.
