Each business is scored on signals we can verify from public data: a live, secure (HTTPS) website, mobile-friendliness, a published phone number and website, and fit with the hvac contractors category. We do not collect or display customer reviews, and we do not accept payment for placement. Businesses can claim their listing to correct contact details, but the rank is fixed by the data.
