Mechanical systems are the heart of your building. They make your building more marketable, more comfortable, and more profitable. A properly designed, installed, and maintained mechanical system reduces your carbon footprint by conserving energy. It also provides a healthier and more comfortable work environment which reduces employee absenteeism and reduces tenant turnover. It can save an owner a great deal of money.

For over 9 decades, owners and builders have selected Horwitz/NSI to design, install, and maintain their mechanical systems. Horwitz/NSI 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.
