W.H. DEMMONS

W.H. Demmons is a design-build-maintain firm specializing in HVAC, roofing, and building automation solutions. We service Maine, New Hampshire, and beyond... Our history began in 1914, with the creation of Demmons Roofing, which offered quality commercial roofing services to clients through the Northeast. Exactly eighty years later, in 1994, the company merged with Maine Air Conditioning, which was founded in 1974, to expand the company into commercial HVAC solutions... With the acquisition of Maine Air Conditioning, W.H. Demmons became a global leader in the HVAC innovation and technology industry, after having completed its first geothermal building in the 1990s.
