Clauss Mechanical Systems is a family owned and operated mechanical HVAC contractor as well as a custom sheet metal fabrication shop. Our company, founded and run by its owners Jay Clauss and his wife Vicki, has over 30 years of experience and we are committed to honest, professional and quality service. Over those 30 years we have grown from a tiny 600 Square ft. shop to our current 10,000 sq. ft. “state of the art” facility. Although our business has grown dramatically we have remained at the same location, as we continue to build upon our long history of professional service and business integrity with the thousands of people and businesses who already know and trust us. We serve all of New Jersey including Bergen, Passaic, Morris, and Essex counties. We also serve New York City and its five boroughs: Manhattan, Bronx, Queens, Staten Island, and Brooklyn. We have the ability for varying requirements from standard to custom Hvac installations, exhaust systems that maximize indoor air quality, and custom metal fabrication. Historical to new construction, residential, commercial, industrial and institutional, Clauss Mechanical Systems is capable of all facets of the heating, cooling and ventilation industry. We have an appreciation for the smaller jobs as well as the larger jobs with the same quality, honest service, and no pressured sales!
