In an industry often characterized by impersonal transactions and technical specifications, SubZero Heating and Air Conditioning, based near Troy, Ohio, stands out as one of a kind. Co-owners Trishanda and Jack Barhorst, a husband-and-wife team, whose people-first philosophy and family business culture set new standards for HVAC service in Ohio.

The couple launched the business during the pandemic, not exactly the most ideal time to get started. But their belief that service is about people and comfort is more than just a temperature setting, has helped SubZero grow into a trusted name across the region.

Jack Barhorst serves as the company’s vice president and lead technician. “We don’t just fix furnaces or install AC units,” he explained. “We show up for people when they’re uncomfortable and stressed. That’s a big responsibility—and we take it personally.”

President and CEO, Trishanda Barhorst, insists that every client at SubZero be treated like a valued neighbor, in every aspect of the business. From the moment a customer calls, they’re met with warmth, transparency, and a genuine desire to help. “When you call us, you are talking to the CEO of the company from start to finish,” Trishanda said.

From last-minute furnace repairs to full system upgrades, SubZero has made a name for itself as the go-to crew for homeowners across the region. Whether it’s routine maintenance or installing a high-efficiency system, their team shows up with know-how and heart—making sure every family stays comfortable, no matter the season.

SubZero also tackles the big stuff—office buildings, retail spaces, and large industrial facilities. Their commercial services are just as personally-focused, and just as precise. In high-pressure environments where systems are complex and every minute counts, business owners count on SubZero’s quick response times, sharp technical skills, and commitment to keeping things running smoothly.

Jack and Trishanda have created a business where customers and employees feel valued and empowered. Their crew doesn’t just know HVAC systems, but empathy and communication—skills that turn service calls into lasting relationships.

“Everything that we have in our success today really centers on the deep sense of trust we have in our relationship and because of that, we’re able to share that with others,” Trishanda said. “Employees, customers, friends, it gives us something of high value that we can pass on to others. Every person requires differently, with a different set of needs. We always want to leave something with them that matters.”

“We want your equipment to work and when it doesn’t, we’re there to fix it,” said Jack Barhorst. “Call us and we’ll get it back up and running so you can get back to your business.” (Meet the SubZero Office Assistant – Liberty)

As Trishanda and Jack look to the future, their vision remains rooted in the same principles that launched SubZero: family, service, and heart. In an industry that can sometimes feel cold, they’re proving that warmth starts with people.
