Meeting the HVAC Needs ofPlainfield, Illinois for More than 80 Years

We have been serving the heating and air conditioning needs of Plainfield since 1932. We were replacing and servicing boilers and furnaces in Plainfield long before the word HVAC had even been invented. Interestingly, we have installed modern, ductless ac systems in very old Plainfield buildings that cannot have ductwork. Lockwood Furnaces specializes in finding the best solutions for any Plainfield HVAC problem. We have grown with the heating and cooling industry, but we have never forgotten our roots. We were, and remain, a family business that is part of the Plainfield community.
