The state of HVAC digital presence: 21,918 US HVAC contractors analyzed
We analyzed 21,918 US HVAC contractors across 589 cities in 48 states. 20.2% operate with no website at all, the average public rating is 4.77 stars, and 98% publish a phone number — a first-party snapshot of how digitally present the HVAC trade actually is.
4,417 HVAC contractors have no website — and most are thriving anyway
Of the 21,918 HVAC contractors in the corpus, 4,417 (20.2%) have no website on their public listing. Not an outdated site — none. Every prospect who finds them lands on a bare profile, reads a handful of reviews, and guesses.
These are not failing businesses. The average public rating across the 21,127 rated HVAC contractors is 4.77 stars with a median of 55 reviews — sustained, real customer demand. The gap is visibility, not viability, which is exactly the gap a marketing agency closes.
21,395 of them (98%) publish a phone number, so the no-website segment is reachable today by anyone who bothers to call.
Review-count distribution
| Reviews | Businesses | Share |
|---|---|---|
| 1–9 reviews | 4,222 | 20% |
| 10–49 reviews | 5,949 | 28% |

Share of the 21,127 HVAC contractors with at least one public review. Median: 55 reviews.
How stale are the websites that do exist?
For 913 HVAC websites with measurable public web-archive history, we dated the last substantive content change. 12% of that subset haven’t meaningfully changed in 19+ months — the textbook redesign pitch.
| Last substantive change | Sites | Share |
|---|---|---|
| Within the last 6 months | 722 | 79% |
| 7–18 months ago | 82 | 9% |
| 19–36 months ago | 24 | 3% |
| More than 3 years ago | 85 | 9% |
Denominator: the 913 sites with archive history — a subset of the full corpus, not all 21,918 businesses.
Reachability: who answers a cell phone?
Of the 428 HVAC phone numbers we’ve run through carrier-grade line-type verification so far, 115 (27%) are mobile lines — the owner’s own pocket, not a front-desk landline. Line-type checks run per-scan, so this subset grows with the corpus; the percentage describes verified numbers only, not all 21,918 businesses.

Methodology
First-party data: 21,918 US HVAC contractors across 589 cities in 48 states, profiled from public business listings and public-web signals. Corpus snapshot: April 2026. Headline percentages use the full analyzed corpus as denominator; line-type and site-staleness figures describe the explicitly stated subsets where those signals have been verified. Figures refresh as the underlying corpus grows — this page always renders the live aggregate, never a frozen copy.
Public-sector demographic data
Population, household income, home value, homeownership rate, median year structure built and self-employment density come from authoritative public demographic releases. Refreshed annually.
Live business records
Business names, addresses, ratings, review counts, websites, phone numbers and operating status come from live business records. Each profiled business is re-checked regularly so stale data drifts off the page.
Composite vulnerability score
We blend 19 signals (review velocity, star rating, website presence and freshness, ad pixels, hiring activity, competitor density and visual brand, plus eleven more) into a 0–100 score. Higher means more likely to engage with marketing services.
