The History of Weber & Grahn

Fifty years ago – in 1968, Fred Weber and Eric Grahn opened the doors to their dream job – owning and operating their own HVAC company. The pair worked together at Carlton Stuart – Carrier’s largest distributor in the Northeast. Their experiences as seasoned naval mechanical engineers and HVAC professionals were a perfect fit for the burgeoning market of central air conditioning installations on the East End of Long Island.

Weber & Grahn grew along with the development of the East End.

Its success stemmed, in part, from Fred and Eric’s ability to achieve the sophisticated design requirements that architects and homeowners desired.Weber & Grahn was

installing geothermal systems in the early 1980s to meet customers’ demand for quiet, unobtrusive cooling systems! Today we continue to design and install heating and cooling systems that exceed homeowners’ expectations of comfort and affordability using the latest technologies and designs coupled with tried and true experience.

Most importantly, Weber & Grahn’s reputation grew through word of mouth as influential customers passed along their experience with Weber & Grahn’s can-do attitude. In 1982, Fred and Eric created W&G Service Company to be dedicated solely to HVAC service and support. After Fred Weber retired in 1985, Craig Rietmann joined Eric and his sons Larry and Gregory and began to grow the companies from 25 employees to its current 80 person roster. The company continues to grow. Weber & Grahn’s owners, office staff, and field are committed providing the best customer experience of, installing the best and fixing the rest.
