By the time David Capestany purchased Zinger Sheet Metal Co., Inc. from his father, Nelson, in 2013, the company had completely shifted focus from residential HVAC to commercial.

“Really, up until 2005, we were maybe 70 percent residential and probably 30 percent commercial,” says David, who helped run the company for several years before officially becoming president. “By 2008, it had completely flipped flop. Now we are probably 90 percent commercial and 10 percent residential.” The change of business also marked an increase in revenue for the shop, from averaging $1.2 million in topline revenue to on track to make $3.5 million this year.

Brothers Henry and Harold Zinger started Zinger Sheet Metal in 1954 out of a garage not far from the shop’s current location in Grand Rapids, Michigan. Engaged to Henry’s daughter, Nelson Capestany started working for his future father in law after completing basic training for the U.S. Army.

“It was probably incentive that I was going to marry his daughter,” Nelson says with a smile. After initially buying a stake in the company with his brother in law, he took majority ownership in the ’90s.

Three generations later, David is focused on strengthening the shop’s legacy as a partner with its customer base.

“I think one of the things that has probably stayed consistent through the years, whether it was back in the ’70s and ’80s, is trying to be a partner with our customers,” he explains. “Trying to figure out whatever piece we can play to help their businesses be more profitable.”

In its 20,000-square-foot facility, Zinger Sheet Metal offers spiral and rectangular ductwork fabrication for HVAC and industrial contractors and CAD fabrication services. Known for taking on the “more difficult” level job, the shop prides itself on giving customers what they need.

“Some of our core values are customer service, exceeding customer expectations and trying to deliver each order in a way that will earn the next order,” says Capestany. “In some places, they probably push more towards standardizing everything.”

He adds, “We are going to give you what you need as opposed to telling you what you have to have.”
