How this list was made
We pulled 242 Tucson-area HVAC contractors from Google Maps, then kept the 110 with a rating of 4.0 or higher and at least 10 reviews. The average rating in this group is 4.83 stars.
Ratings with only a few reviews are pulled toward that average, so a business needs a real track record to reach the top. Nobody pays to be here. Read the full method.

We started with 242 Tucson-area businesses from Google Maps and kept the 110 with at least a 4.0 star rating and 10 or more reviews. Each rating is then weighted by how many reviews back it up, so a perfect score from a handful of reviews does not outrank a near-perfect score from hundreds.
