Our top 10 hvac companies in San Antonio

San Antonio summers routinely push into the triple digits for months at a time, and a failed AC unit here is more than an inconvenience, it is a real risk for anyone elderly, very young, or managing a health condition. That urgency draws plenty of companies that are better at advertising than at showing up on time, which is why this list sticks to real, well-reviewed local businesses with a physical San Antonio address, a rating of at least 4.7 stars, and a review count in the hundreds or thousands rather than a handful. Every company below was checked against the same criteria: an operational Google Business Profile, a real company website rather than a lead-generation page, and a location genuinely inside San Antonio rather than a neighboring suburb with a San Antonio-sounding address. Texas HVAC contractors are licensed through the Texas Department of Licensing and Regulation under a TACLB or TACLA number, and homeowners should always ask for that number and verify it directly with the state before signing a contract for any sizable repair or system replacement. Several companies on this list also handle plumbing or electrical work, which is worth knowing if you would rather make one call than three when more than one system in the house needs attention.

How we chose the best hvac companies in San Antonio

Read our full ranking methodology →

This list follows Google's own ranking order for HVAC contractors serving San Antonio, Texas, as returned in September 2026. Every company includes a Texas address inside San Antonio city limits, a Google rating of at least 4.7 stars, and a review count of at least 50. Ratings and review counts were read directly from each company's Google Business Profile and are current as of the review date shown on each listing. No company paid for placement on this list.

How to choose a hvac company in San Antonio

  • Verify insurance and credentials

    Ask for a current certificate of insurance and confirm registration or licensing with the authority that issues it, not with the company.

  • Ask for a written estimate

    Scope, materials, removal, disposal and who pulls the permit should all be named on the page rather than agreed on the doorstep.

  • Compare multiple quotes

    Two or three bids on the same scope. A number far below the others usually means something has been left out of it.

  • Understand the warranty

    Separate the manufacturer's warranty on materials from the company's own warranty on the work, and get both in writing.

  • Ask who performs the work

    Find out whether the crew are employees or subcontractors, and who supervises them on the day.

  • Check recent local projects

    Ask for addresses or photographs of comparable jobs finished nearby in the last year or two.

  • Avoid high-pressure sales

    A discount that expires today, or a knock on the door after a storm, is a reason to slow down rather than sign.

  • Get everything in writing

    Change orders, timeline and payment schedule included, before the first payment changes hands.

Questions to ask before hiring

  • Are you insured, and can you send the certificate?
  • How long have you worked in this area?
  • Will you provide a written estimate with materials listed?
  • What warranty do you offer on the work itself?
  • Do you use subcontractors for this job?
  • Who handles permits and inspection?
  • What would you recommend here, and why?
  • How are unexpected costs handled once work starts?
  • What is the estimated timeline from start to finish?
  • Can you provide recent local references?

Red flags

  • No verifiable local business address or registration
  • Pressure to sign on the first visit
  • A demand for full payment up front
  • An offer to cover or waive your insurance deductible
  • Refusal to put warranty terms in writing
  • A quote that will not itemize scope

HVAC companies in San Antonio FAQs

  • How do I check if a San Antonio HVAC contractor is actually licensed?

    Texas HVAC contractors are licensed through the Texas Department of Licensing and Regulation under a TACLB or TACLA number. Ask for that number directly, confirm it is active, and make sure it matches the business name on your quote before signing anything.

  • How much does AC repair cost in San Antonio?

    Several companies on this list, including Goettl and ASC Heating & Air, offer free diagnostic visits and estimates before any work begins. A full system replacement costs significantly more than a repair, so get at least two quotes and ask about financing if you're facing a full replacement unexpectedly.

  • Why does my AC struggle to keep up during a San Antonio summer?

    San Antonio regularly sees daytime highs in the high 90s and triple digits from June through September, which pushes any AC system near its rated capacity for months at a time. An aging or undersized unit, poor attic insulation, or leaky ductwork can all make a system run constantly without ever catching up, which is why several companies on this list offer a free second opinion before recommending a full replacement.
