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. Owners can claim a listing for a Verified badge and a direct link; sponsors appear only in labeled blocks outside the numbered list. Neither changes rank.

Each listing is scored on public signals we can check ourselves: whether the website is live and secure (HTTPS), whether it works on a phone, whether a phone number and website are published, and how closely the business matches the hvac contractors category. We do not collect customer reviews, so no star ratings or review counts appear here, and no business pays for placement.
Use this list to shortlist two or three hvac contractors, then read their Google reviews yourself, confirm license and insurance, and get written estimates before committing. The score here is a filter, not a verdict.
Licensing in Maryland runs through the Maryland Home Improvement Commission (MHIC) under the Department of Labor. Before hiring anyone in Cambridge, look the contractor up in the Maryland Department of Labor's public license search and ask for their MHIC number; plumbers, electricians, and HVAC techs are licensed by their own state boards. Also confirm current liability insurance, and get the license number in writing on the estimate.
