TL;DR

  • 20 verified hvac businesses operate in Houston, Texas - all sourced from active Google Business Profile data.
  • Top pick: Air Star Now with a ServiceAgent Score of 8.6/10 (656 reviews, 5.0★ average).
  • 8 elite-tier providers (ServiceAgent Score 8.5+) and 0 owner-verified listings.
  • Typical cost in Houston: $150 - $4,200 - $385 median for a single-system repair, $7,400 median for a full residential replacement.
  • 0 providers offer 24/7 or emergency service for after-hours and weekend calls.
  • Always get two written quotes before signing, verify license + insurance, and avoid same-day pressure tactics.

Why trust this list

When you need hvac work done in Houston, the first hour of research is usually the most expensive part - reading reviews, decoding marketing claims, and trying to figure out who's actually a licensed pro vs. someone with a truck and a Google listing. This page is meant to compress that hour into about five minutes.

We've cataloged every active hvac business in Houston, Texas (20 total) and ranked them by a single composite ServiceAgent Score - a weighted blend of *trust signals* (data quality, verification status, review-volume credibility) and *quality signals* (rating, review count, response time). The result is a list where high-volume, well-reviewed, complete-data providers float to the top, and where a "5-star from 3 reviews" outfit doesn't get to outrank a 4.7★ provider with 240 reviews.

Below: the ranked list (top 20), followed by what to look for, what each project usually costs in Houston, the red flags that should make you walk, and a methodology section that shows our exact formula. If you run one of these businesses, the Claim your listing banner near the bottom takes you through a 2-minute verification flow to get a green badge, edit your description, and bump your placement.

How we chose these

We start from every active Google Business Profile in Houston tagged hvac, then score each business on two dimensions:

Trust Score (40% of the composite, 0-10) rewards owner-verified status (claimed listings get a 3-point bump), completeness of contact information (phone, website, address, hours, coordinates, photos, service categories), and review-volume credibility - a provider with 200+ reviews is treated as more trustworthy than a provider with the same star rating but only 5 reviews.

Recommendation Score (60% of the composite, 0-10) is the Google star rating shrunk toward the category mean using a Bayesian prior. Without this step, "5.0 from 2 reviews" would outrank "4.7 from 240 reviews" - which is exactly backwards. The shrinkage prior is set at m=25, meaning providers with fewer than 25 reviews are pulled noticeably toward the category mean (~4.8).

Composite ServiceAgent Score = 0.6 × Recommendation + 0.4 × Trust. We re-compute as new reviews land and as providers claim their listings. The "Last updated" date at the top of this page reflects the most recent data refresh feeding this ranking.

What we deliberately don't do: pay-to-rank, sponsored slots that masquerade as editorial picks, or hide our formula. Sponsored slots (if/when introduced) will be clearly labeled and won't affect editorial ranking.

Local context

$Houston sits in $Texas's broader hvac services market, which our data suggests has 20 actively-operating providers within the city limits and surrounding metro. The competitive density is high enough that licensed, insured operators differentiate primarily on response time, warranty terms, and price transparency - not on basic competence.

Pricing drivers in Houston

  • System age (units over 10 years are more likely to need replacement vs. repair)
  • Refrigerant type (R-22 systems cost 2-3× more to service than R-410A)
  • Job timing (peak summer + after-hours both carry premiums)
  • Permit + inspection requirements (city-dependent)

What to verify before signing

  • Licensed in your state (verify on the state contractor board)
  • Carries general liability + worker's comp insurance
  • Provides itemized written estimate before work begins
  • Offers at least a 1-year warranty on parts AND labor
  • Is NATE-certified or factory-trained on your unit's brand

Red flags to walk away from

  • ⚠️ Refuses to put the diagnostic fee in writing before arriving
  • ⚠️ Pushes "full system replacement" without showing you the failing part
  • ⚠️ Charges over $200 just to drive out without a price band quoted in advance
  • ⚠️ No EPA Section 608 certification on file (required to handle refrigerant)

Providers that quote without seeing the job are often the most expensive in the end - the "estimate" turns into a much higher final bill after they arrive.

Are these hvac listings verified?

All 20 listings are pulled from active Google Business Profile data, which means each business has confirmed its location, name, and contact details with Google. Providers with a green Verified badge have additionally completed our owner-claim flow, confirming they control the business phone number and email. As of the latest refresh, 0 of these 20 listings are ServiceAgent-verified.

How does the ServiceAgent Score work?

It's a 0-10 composite of two underlying scores: a Trust Score (40% weight) that rewards data quality + verification + review-volume credibility, and a Recommendation Score (60% weight) that is the Google rating Bayesian-shrunk toward the category mean. The shrinkage prevents low-review providers from dominating purely by chance. Full formula on the methodology page.

Can I get free quotes from multiple hvac providers at once?

Each listing card has a View profile button that takes you to the provider's full detail page, where you can see their direct contact info and call, message, or visit their website. ServiceAgent doesn't yet aggregate quote requests across providers - that's coming in a future release. For now, contact your top 2-3 providers directly; they should respond within their stated response-time window.

Why does the ranking change between visits?

Two reasons. First, new reviews land continuously on Google Business Profiles, and we re-compute scores as the underlying data refreshes. Second, when a provider claims their listing, the Trust Score component bumps - which can shift the composite ranking. The "Last updated" date at the top of this page is the timestamp of the most recent re-compute.

I'm a business owner - how do I get my listing on this page?

If your business has an active Google Business Profile in Houston tagged hvac, it should already be here. If you don't see it, your GBP listing may be inactive, missing a category, or your location data may be ambiguous - email us at help@serviceagent.ai and we'll investigate. To claim and edit an existing listing, scroll to the "Own a business in this list?" banner near the bottom of this page.
