A city-by-city guide to HVAC and plumbing pros.
ProComfort Registry lists 43,852 HVAC and plumbing businesses across 3,949 US cities, scores them on public signals, features standout companies in each city, and invites every owner to confirm their own details.
Who publishes it
ProComfort Registry is published by Genovation AI, 4-1400 Grahams Lane, Burlington, ON L7S 1W3, Canada. Genovation AI builds AI call answering, missed-call booking and other growth tools for home-service businesses. The Registry is run as a separate editorial product with its own inbox: registry@procomfortregistry.online.
How listings are built
Each record starts from public business information — business listings, review platforms and the business's own website — and is cleaned, de-duplicated and classified by trade. Every business is scored the same way on reputation, digital presence and reach. Read the methodology for the exact weights.
How companies are selected and featured
In each city we select a small number of HVAC and plumbing companies to feature for the year. Selection is editorial and based on public signals: review ratings and volume, how long the business has operated, and how complete its public record is. Featured companies are marked Featured · City 2026 and appear first on their city page.
We email featured companies to let them know and to ask the owner to confirm three things: the best phone number, who answers calls after hours, and whether they serve residential or commercial customers. Owners can then complete their profile, or ask us to remove it.
Editorial independence
Listings and rankings are never influenced by whether a business buys anything from Genovation AI. There is no paid placement, a higher score can't be bought, and confirming a listing is free. After confirming, owners may be offered an optional free review from Genovation AI; saying no changes nothing about their listing.
Corrections and removal
Owners can correct their record through their private link or by claiming the listing, and anyone can report an issue or request removal. We review every request, usually within one business day.
