Weber & Grahn

What Weber & Grahn does

Weber & Grahn is a privately held HVAC services company headquartered at 216 East Montauk Highway in Hampton Bays, New York, founded in 1968 by Fred Weber and Eric Grahn — both former naval mechanical engineers who had previously worked at Carlton Stuart, Carrier's largest distributor in the Northeast. The company designs, installs, and repairs heating, ventilation, air conditioning, and refrigeration (HVACR) systems for residential and light commercial customers across Long Island's East End, including East Hampton, Southampton, the Hamptons, Westhampton, Riverhead, Sag Harbor, Smithtown, Islip, and surrounding communities. Its service portfolio spans traditional gas furnaces and boilers, central air conditioning, heat pumps, ductless mini-splits, geothermal systems, indoor air quality and ventilation solutions, smart/connected thermostats, and specialized wine-room and commercial refrigeration — the latter targeted at wine collectors and restaurants — delivered by NATE-certified technicians with 24/7 emergency availability.

The company operates a blended revenue model: one-time revenue from equipment sales and installation projects, on-demand professional service revenue from repair calls (with service vans stocked with parts for quick turnaround), and recurring subscription revenue from preventative maintenance contracts branded as W&G Service. Weber & Grahn is a Warranty Service Provider for several major OEMs — Carrier, Trane, Bryant, Lennox, and Mitsubishi Electric — and also installs and services equipment from Bosch FHP (WaterFurnace), Bryan, ClimateMaster, Comfort-Aire, Daikin, EuroCave, Fujitsu, LG, Rheem, and York. Go-to-market is direct field sales with on-site estimates, supported by local SEO, content marketing, Facebook and Instagram presence, customer testimonials, and community involvement; the company holds New York State Master Plumber (#36162-MP) and Master Electrician (#38242-ME) licenses, is BBB-accredited, and holds memberships in ACCA, ASHRAE, NATE, and PCALI.

Ownership remains with the founding family, with Gregory Grahn (likely second generation) acting as the primary operational contact. The company is privately held with no disclosed outside capital, no funding history, no subsidiaries, and no M&A activity in the source material. Marketing copy positions it as a "Gold Standard of HVAC" and a pioneer in the industry since 1968, with a 50th anniversary milestone noted on its website; competitive advantages cited are NATE-certified technical staff, the founder's Carrier-distributor lineage, and depth of specialization in complex residential installations (custom architectural integration, indoor pool dehumidification).
