Boiler Expertise Rooted On Cambreleng Avenue
Number One Boiler Service is a licensed Bronx contractor focused entirely on heating plants. Our technicians hold OEM training on Weil McLain, Burnham, Peerless, Navien, and Lochinvar equipment, backed by NYC gas work qualifications. Every visit starts with combustion readings and system pressure checks, so recommendations are grounded in measured data rather than guesswork. Whether the job is a full boiler replacement, a stubborn no heat call, or a scheduled tune up, you get code compliant workmanship, documented results, and pricing agreed in writing before we open a wrench.
