Zinger Sheet Metal Co

Zinger Sheet Metal Co has operated from Grand Rapids since 1954, building a seven-decade legacy as West Michigan's go-to custom duct fabricator. The company holds an A+ rating with 4.5 stars from 11 client reviews, reflecting decades of consistent craftsmanship. Their 13,500-square-foot manufacturing facility on Roger B Chaffee Boulevard produces rectangular, round, and oval ductwork serving HVAC contractors across the Midwest. Homeowners seeking custom duct lengths or specialty fittings typically engage Zinger through their contractor, though the shop welcomes walk-ins for will-call pickups.

What distinguishes Zinger is their technology-forward approach and minority-owned business status. The company developed a custom KURBULATOR app, a curb adapter configurator that lets contractors input measurements and receive instant fabrication specs, reducing ordering errors and project delays. Their lean manufacturing methodology keeps lead times short while maintaining precise tolerances. Unlike commodity suppliers, Zinger specializes in rooftop products and curb adapters enabling retrofits of older HVAC systems with modern high-efficiency units. This technical expertise combined with in-house fabrication capability positions them as a problem-solving partner rather than a simple parts vendor.

Client testimonials underscore the team's responsiveness and expertise. Reviewer Brian Roark specifically names David Capestany, calling him trustworthy enough to trust with his life, a testament to the care taken on client projects. Another customer mentions Zinger built custom duct lengths for their home, while a third praises the counter staff for guiding a customer who arrived without knowing exactly what they needed. Brett Evans highlights fast and efficient service, and multiple reviewers mention friendly staff at the shipping and receiving desk where pickups begin at 6 AM.
