Air conditioning contractors in Texas

Texas licenses this trade at state level through the Texas Department of Licensing and Regulation, so one search covers the whole state. This page holds 20,468 licenses, copied from the TDLR file published 2026-10-22. Then say what the job is, and each result says whether the licence reaches it — not just whether it exists.

What this file says about itself

Every figure here is as of 2026-10-22, the day TDLR published the file — not as of today. That is deliberate: a count of current licenses recomputed on each page view is a different number every day and a wrong one the moment the refresh stops.

• 20,468licenses in the file
• 19,12593% of the file — still unexpired on that date
• 1,3437% of the file — past their expiry date on that date
• 3,460still live, but due to expire within the following 90 days

That last figure is the reason a license check has a shelf life. 3,460 of these licenses lapse within three months of the file’s own date unless they are renewed, and a printout of this page taken today can be wrong about any of them by the time the work starts.

TDLR’s published file carries no status column. There is no field in it saying active, suspended or revoked, so standing on this page is read from the expiry date — and an expiry date cannot know about a suspension. A license can be suspended with years left on it. (TDLR’s own record page does print a status; it is the bulk file this page is built from that does not.) TDLR’s own lookup is the only thing that can tell you which.

License class and endorsement

A TDLR license is not one thing. It carries a class, which sets the size of system it may be worked on, and an endorsement, which sets the kind of work — and a contractor who is licensed is not therefore licensed for your job. Every result above says which, in words, and will tell you whether it covers the job you describe.

The class decides the size of the job

TDLR states that a Class A license “allows you to work on any size unit”, while a Class B license “allows you to work on cooling systems of 25 tons and under, and heating systems of 1.5 million BTUs/hour and under”. A Class B holder is licensed; they are not licensed for every job.

The endorsement decides the kind of work

TDLR lists three: environmental air conditioning, which is comfort heating and cooling for people; commercial refrigeration, which is equipment keeping a space cold for its intended use; and process cooling or heating, which is temperature control for production. A third code, C, is what §75.22 calls a combined endorsement — one license covering both — and it is on 7,927 of the licenses in this register — 5,714 as AC and 2,213 as BC — even though TDLR’s file-format document does not list it. §75.22(e) covers the other case: “a contractor who has endorsements of different classes will be issued a separate license number for each endorsement”, so a code like AEBR is one holder with two licenses.

The code beside each license is TDLR’s own. 16 Texas Administrative Code §75.22 sets the format — Title/Class/Number/Endorsement code — and names the endorsement letters, so every code in this register reads as a scope of work:

A holder with endorsements of different classes is issued a separate license number for each, which is why some codes above are two pairs. Each share is rounded to the nearest whole percent and the small ones read under 1%, so that column does not add to exactly 100; the counts beside it add to 20,468, and they are the figures to read.

Which licences reach which job

The picker above asks the reader for the job and the results answer it. This is the same answer, worked out from 16 Texas Administrative Code §75.22 for ordinary jobs on both sides of the two ceilings a Class B license has, so it can be read without searching — and so the page states it rather than promising it.

A code in neither column is one the rule cannot settle for that job without a figure the reader has not given — every Class B code on a job with no size named, which is the last row and the commonest state to be in. Those licenses, with the 1 the board left blank, are the ones the search returns as ask TDLR. Size bites only on Class B: a Class A code is ruled out by the kind of work or not at all.

Where these licenses are held

TDLR records a county against each license, and this file names 232 distinct ones, plus 711 licenses it records as held out of state — held by someone licensed in Texas who is not based in it. The county appears beside every result because two holders often share a name and the county is what tells them apart. It is also what a place word in your query is checked against — but only a word the name did not account for, and only once another word has matched the name. So the county column alone will not find anybody: a county typed on its own returns only the businesses and holders whose name carries that word, while a county typed beside a trade returns the holders in it.

The twelve largest of 232 counties in the file. The rest are in the register and searchable; they are not listed because a table of 232 rows is not something anyone reads.

What a result here means

It means the TDLR file of 2026-10-22 recorded that license with that expiry date. It does not mean the license is current right now: a license can be suspended or revoked between the board’s files, and this copy would not know. That is why every result links to TDLR’s own lookup, and why you should use it before hiring anyone.

If a name is not here

A license issued after 2026-10-22 will not be in this copy. An air conditioning and refrigeration contractor license is the one that may contract the work. TDLR separately registers and certifies A/C technicians, who are not on this page. This is the register an HVAC contractor in Texas appears in: TDLR licenses the trade under the name air conditioning and refrigeration, and issues nothing called an HVAC license.

Texas licenses electricians and air conditioning contractors at state level, but most general contractors and roofers are not licensed by the state at all, so there is no state record to check. For those, ask your city or county building department.

What Texas licenses, and what it does not — and what a license covers, which is less than most people hiring a contractor assume.
