The third generation of our family serving yours.......


Keystone heating was started in 1918 by William Challinor. Our grandfather, David Lonergan, went to work at Keystone in the '20's and bought the business in 1934. Our father, Lowell Katt, started at Keystone in 1951 and took over in 1969. David Katt started in 1975, Marshall Katt in 1978 and Colleen (Katt) Miskovic in 1979. We took over as owners in 1995. We are union shop, represented by Sheet Metal Worker's Local 18 and currently have a total workforce of 12 people. Keystone is proud to serve the Racine-Kenosha area with high quality, friendly and dependable work.
