General Info

For 100 years, owners and builders have selected Horwitz to design, install, and maintain their mechanical systems. Horwitz has gained a wealth of knowledge since it’s founding in 1918, and we have been partners on some of the largest and most important projects ever built in the Twin Cities. Horwitz specializes in new construction, renovation, and retrofit of commercial, industrial, and institutional facilities. We provide engineering, design, installation, and ongoing service support for the heating, refrigeration, air conditioning, sheet metal, and plumbing markets in the Twin Cities.
