Horizon Group Holdings (“HGH”) has announced that it is purchasing First Class HVAC, a trusted provider of heating, cooling and plumbing services in Millsboro, DE. The partnership marks HGH’s fifth acquisition this year.

First Class HVAC was founded forty years ago and operated as a family-owned business before current owner and company president Tim Pulice bought it in 2011. The company serves southern Delaware and eastern Maryland.

First Class has built a reputation as an innovator, advancing new technologies like indoor air quality, tankless and solar water heaters, and ductless heating and cooling systems. It also does crawl-space encapsulation, a valued service in the coastal areas the company serves.

“Horizon made the whole process incredibly easy,” said Pulice. “They clearly know this business and will be able to provide our people with even greater opportunity than we’ve been able to offer.

Charlie Haines, CEO of Horizon Group Holdings, said, “We’re happy to have First Class HVAC join our family of brands. Their organization and their people will fit right into our operation. Working together, I’m sure we’ll be able to give their customer even better service and offer their employees even more growth opportunities.

Horizon Group Holdings is always looking for strong local companies like First Class HVAC to grow to its portfolio of outstanding local contracting firms. HGH looks for home services companies that want to provide outstanding customer service and professional development for employees.
