Built by installers, since 1964.

Honnecke Manufacturing — legally H Manufacturing, Inc — is a family-owned manufacturer in Golden, CO. We started because the people doing the installs were tired of generic products and a lack of real innovation. So we built our own.

Everything we make is designed for the trades that use it — HVAC and furnace techs, electricians, solar installers, and plumbers. Our products are engineered to adjust to unique jobs, connect fast to all major furnace manufacturers, and make routine service simple. Less time on site, fewer callbacks.

We build from G90 galvanized steel using domestically sourced materials and local labor. Our designs are patented (U.S. Patent #6076780) and proven on thousands of installs, from apartment-style spaces to large residential systems.

When you call, a real person answers. We'll help you spec the job, send you spec files and install videos, and get you bulk or wholesale pricing.
