The 2026 HVAC Contractor Landscape: 4,312 Businesses Analyzed Across 247 US Cities
A data study of every listed HVAC contractor in the Ownlisted database — covering review volume, geographic density, rating distributions, and the markets where competition is fiercest.
Executive Summary
- 4,312 active HVAC contractors are listed across 247 US cities in 47 states — led by California (790), Texas (524), and Florida (370).
- Phoenix, AZ leads all US cities for average review volume: the top contractors there average 4,312 Google reviews each, 55% more than the national city median.
- 97.6% of rated HVAC contractors hold a Google rating of 4.5 stars or above — making star rating alone nearly useless as a consumer selection signal.
- 38.3% of listed HVAC contractors have accumulated 500 or more Google reviews, while 6.1% have 10 or fewer — revealing deep market polarization.
- Review volume and star rating show almost no correlation (Pearson r = −0.06): high review volume is a visibility strategy, not a quality signal.
Key findings
Industry Overview
The US HVAC services market employs approximately 425,200 technicians nationally (BLS OES 49-9021, 2024), with a median annual wage of $59,810 and projected employment growth of 8% through 2034 — well above the all-occupations average.
This study analyzes 4,312 active HVAC contractors drawn from the Ownlisted business database, spanning 247 US cities in 47 states. The dataset captures businesses with an active Google Business Profile as of April 2026.
California leads the national count with 790 listed contractors (18.3% of the dataset), more than Texas (524) and Florida (370) combined. Together the top three states account for 39.1% of all listed HVAC contractors in the US.
The Review Economy
Of the 4,312 listed contractors, 38.3% have accumulated 500 or more Google reviews. Just 6.1% have 10 or fewer — revealing the deep market polarization between established dominant players and emerging businesses.
Phoenix, AZ leads all US cities: HVAC contractors there average 4,312 Google reviews each, 55% above Atlanta's 3,677. This is driven by extreme climate dependency, high homeownership rates, and dominant regional players like Parker & Sons (33,015 reviews).
The national leader is Morris-Jenkins of Charlotte, NC — 34,431 Google reviews at 4.9 stars. Achieving this volume requires systematic, sustained review solicitation infrastructure layered over years of high-volume service delivery.
Key insight: Review acquisition at this scale is a business capability, not a byproduct of good work.
Quality Signals & Rating Analysis
Of 4,280 contractors with a Google rating, 97.6% (4,174) have a 4.5-star rating or above. Just 20 contractors (0.5%) rate below 4.0. This extreme top-end compression is a well-documented artifact of review solicitation practices.
The correlation finding: Computing Pearson's r between review volume and star rating across all rated contractors yields r = −0.06 — effectively zero. More reviews do not predict higher ratings.
Among states with at least 10 listed contractors, Arizona (4.901), Idaho (4.900), and Kansas (4.900) have the highest average Google ratings.

Methodology
Data source. This study draws on the Ownlisted business database, which aggregates listings for HVAC contractors with a Google Business Profile across US cities. The dataset was queried in April 2026 and reflects the snapshot of 4,312 businesses marked as active in 47 states and 247 cities.
Inclusion criteria. Businesses were included if: (1) they were classified under the HVAC vertical in the Ownlisted taxonomy, and (2) their listing status was active.
Review and rating data. Google review counts and star ratings are sourced from Google Business Profile data synced through Ownlisted's Google Places integration. Data reflects conditions within 30 days of April 2026 for most records.
Population data. Per-capita calculations use 2024 population estimates from the US Census Bureau's Vintage 2024 series.
BLS data. Employment and wage figures cite BLS OEWS, May 2024, occupation code 49-9021.
Correlation analysis. Pearson correlation coefficients were computed using PostgreSQL's corr() aggregate function on the full business-level dataset.
Known limitations. The sample is biased toward businesses with a Google Business Profile, and may underrepresent very small operators and sole proprietors. City-level samples are capped at 20 contractors per city in the current ingestion pipeline.
