Hire an HVAC pro whose license we've already checked.
Most listings start as a real license on a state board's register, some as a public permit filing — either way, a listing earns its verified badge only after a cross-check against a second public record. Honest cost guides, no pay-to-play rankings — always free for homeowners.
A license number alone means less than you'd think
Here's how a listing earns the verified badge. We check licenses against state records; we do not inspect workmanship.
State license register
Most companies here start as a real license pulled straight from a state's own contractor licensing board, such as Texas's TDLR or California's CSLB. The rest come from city permit records or public business data and stay unverified until we can match them to a license.
Cross-checked wherever the register alone isn't enough
Some states' own registers already carry a real phone number and address. Where one doesn't — Texas's TDLR list is the clearest example — we cross-check it against a second, independent register (state sales-tax filings), matched on county, since business names repeat (Texas alone has eight separately licensed "Mendoza HVAC" firms).
Badge only once we're confident
No confident match, no verified badge. A listing only carries it once the license is matched to the right business in the right place.
What "verified" doesn't mean
We don't inspect anyone's workmanship — verified means the license checks out, not a guarantee of the job. Ask any contractor for their number directly and check it yourself against your own state's board — it takes about thirty seconds.

Is AirProHQ free to use?
Yes — AirProHQ is always free for homeowners. There's no sign-up, no account and no fee to search the directory or contact a contractor.
What does the "verified" badge actually mean?
It means the license number checks out against that contractor's own state licensing board. In Texas specifically we also cross-check it against a second independent register (state sales-tax filings), matched on county, for extra confidence — other states are verified directly against their own official licensing lookup. It isn't a workmanship guarantee; see our hiring checklist for what else to ask before you book.
How many contractors and cities does AirProHQ cover?
AirProHQ currently lists 30,556 contractors across 943 cities in 26 states, and we're adding more every month.
Where does AirProHQ's contractor data come from?
Most listings start as a license pulled from a public state contractor register; some start as a public building-permit filing instead. Where a source doesn't already carry reliable contact details, we cross-check it against a second independent source to confirm it's matched to the right business. Not every listing has a confirmed license match — the Verified badge shows which ones do. This is about verifying a contractor's identity and license — not aggregating star ratings or reviews.
