Weber & Grahn

For more than 50 years, we at Weber & Grahn have built our reputation around quality air-conditioning and heating systems. Our roots go back to Naval officers Fred Weber of the USS Champlin and Eric Grahn of the USS Rankin, two engineers who combined their HVAC knowledge and established themselves in the Hamptons. Fred, a Stevens Institute of Technology graduate and Professional Engineer, worked for Babcock & Wilcox and Foster Wheeler and held several boiler-design patents. Eric was a United States Merchant Marine Academy graduate, an engineer for Carrier, a licensed Master Electrician, and a Master Plumber. As our HVAC design/build work grew, we created W&G Service Company to support it.

From our Hampton Bays location, we design, install, and service central air systems with close attention to climate control, appearance, and acoustics. Our capabilities include engineering, CAD drawings, and installation for residential and commercial HVAC design/build projects. We have collaborated with architects and builders on showcase homes in the Hamptons, and our experience extends to indoor-pool dehumidification, custom wine rooms, and advanced HVAC control systems. When a budget calls for a different approach, we can value-engineer a project and tailor the design to the client’s needs without compromising our standards for engineering and workmanship.

Our work also includes geothermal heat-pump installation, repair, maintenance, and replacement. We install geothermal heat pumps manufactured by Bosch and Florida Heat Pump, and we provide geothermal warranty service for Bosch, Florida Heat Pump, ClimateMaster, Bryant, Comfort Air, Trane, Lennox, Rheem, WaterFurnace, and other manufacturers. We can provide warranty service even when we did not install the equipment. Our NATE-certified technicians continue their education as technologies advance, and our computerized service vans carry many commonly needed parts.

We also have decades of experience with ductless heat pumps, having begun installing Mitsubishi Mr. Slim systems in 1989 as a quiet, efficient alternative to through-the-wall air conditioning, with the added benefit of heat. Across our services, we focus on thoughtful design, skilled installation, dependable maintenance, and prompt, courteous assistance from our team at 216 East Montauk Highway in Hampton Bays.
