Gundlach Sheet Metal Works

What Gundlach Sheet Metal Works does

Gundlach Sheet Metal Works is a family-owned mechanical contractor founded in 1889 and headquartered in Sandusky, Ohio, with a secondary office in Port Clinton. The company delivers residential HVAC, commercial refrigeration, custom sheet metal fabrication, industrial ventilation, plumbing, and indoor air quality services to homeowners, commercial property owners, and industrial facilities across four Ohio counties — Erie, Ottawa, Sandusky, and Huron. It has been a Carrier Factory Authorized Dealer for 50 years, holds the Carrier Presidential Award and a place in the Carrier Dealer Hall of Fame, and is the only ICB-certified fire and smoke damper inspector in Erie County.

Its core technical capabilities rest on Carrier's product platform (Infinity, Performance, and Comfort series heating and cooling equipment; I-Vu building automation with BACnet, LON, Modbus, and Carrier CCN integration; IntelliSense with ecobee smart thermostats) combined with in-house design/build sheet metal fabrication, custom industrial ventilation engineering, and 24/7 commercial refrigeration service. The company distributes complementary indoor air quality hardware from Nu-Calgon (iWave-R), RGF (HALO-LED), and Global Plasma Solutions, and holds ACCA and SMACNA memberships alongside a state-licensed Master Plumber certification.

The business model is a direct-to-consumer and direct-to-SMB service contractor model. Revenue is generated from one-time installation projects (central AC installations at $5,000–$10,000+), time-and-materials repair work (minor fixes a few hundred dollars; major repairs approaching or exceeding $1,500), commercial refrigeration service, custom sheet metal fabrication, plumbing services, and recurring commercial HVAC maintenance contracts with Basic, Standard, and Full Service tiers billed monthly, quarterly, semiannually, or annually. Customers are acquired through the company website, toll-free and local phone lines, online scheduling, free estimates, Google Business Profile reviews, and word-of-mouth. Pricing is not publicly disclosed at the contract level.
