Demmons is comprised of three sub-companies: Maine Air Conditioning, Demmons Roofing and Demmons Geothermal. W. H.

Portland Sheet Metal, another facet of W.H. Demmons, is a fabrication facility capable of handling a wide range of custom fabrication projects. The sheet metal shop is completely automated and computerized. Our projects consist of air distribution duct work for heating and cooling systems, kitchen hood installation including welded duct work, roofing and ventilation systems. W.H.
