Common questions
How did you pick these companies?
These are the 10 Houston-area AC repair companies with the most Google reviews and a rating of at least 4.0 stars, as of 2026-10-19. We read 200 of their Google reviews in Google's "most relevant" order and summarized what customers say. No company paid to be included or ranked higher.
How long does AC repair take in Houston?
For a quick fix like a bad capacitor or fuse, reviewers across these companies often got a technician out within one to two hours of calling, including during 90-plus-degree afternoons, and the repair itself usually took under an hour. A full system replacement commonly happened the next day after a quote, sometimes the same day. The exception was warranty and new-construction work, where several reviewers across multiple companies describe multi-day or even two-week waits with missed appointment windows and no callback, so ask upfront how the company handles warranty parts and whether loaner cooling is available if yours is delayed.
Do I need a permit to replace or repair an AC unit in Houston?
We could not find an official Houston page that says when AC repair or replacement needs a permit. Replacing a whole system usually needs a mechanical permit in Texas cities, so check with the Houston Permitting Center before work starts, and have your licensed contractor pull any permit that applies.
Does the contractor need a Texas license to work on my AC in Houston?
Yes. Texas requires anyone who installs, repairs or maintains air conditioning, refrigeration or heating systems to hold a TDLR Air Conditioning and Refrigeration (ACR) contractor license, and the company must employ a licensed ACR contractor at each permanent location. You can look up a contractor's license on the TDLR website by license type, number, name or city.
What is the difference between a Class A and Class B license?
A Class A ACR license has no size limit. A Class B license is limited to cooling systems of 25 tons or less and heating systems of 1,500,000 BTU/hr or less, so a Class B contractor may not be licensed for a large commercial job.
Why do some Houston companies have mixed reviews about warranty or new-construction work?
Several companies on this list do warranty and repair work for home builders (DR Horton, Beazer and others). Reviewers who came through a builder's warranty more often describe slow scheduling and installation defects than reviewers who called and paid directly, so if your AC was installed with a new home, ask specifically how warranty claims are handled before you need one.
Before you get quotes
- Ask for the TDLR license numberTexas requires a TDLR Air Conditioning and Refrigeration contractor license to do this work; ask for the number and look it up at tdlr.texas.gov before the crew starts.
- Get a second opinion on any expensive diagnosisMore than one company on this list had a reviewer who got a cheaper, accurate fix from a second company after being quoted thousands of dollars for a full replacement.
- Ask what happens if a warranty part takes days to arriveSeveral reviewers went a week or more without AC waiting on a warranty part with no loaner cooling offered; ask about this before you sign up for a system with a parts warranty.
- Get the diagnostic or service-call fee in writingReviewers across this list report diagnostic fees from about $1 to $200; confirm the fee and whether it is waived if you proceed with the repair.
- Ask how the price compares to the part's retail costA few reviewers found a large markup on small parts like capacitors and motors; it is reasonable to ask what you're paying for labor versus parts.
- Check what the warranty actually covers before a big purchaseReviewers describe both strong and weak follow-through on parts and labor warranties after a full system replacement; get the terms in writing.
