Casteel Heating and Cooling, a premier residential provider of heating, cooling, plumbing and electrical, announced the opening of a new office in Gwinnett County. The new location in Lawrenceville will connect more customers in Fulton, Dekalb, and Gwinnett counties to Casteel technicians and service.

In July, Casteel was acquired by Wilmington, Delaware based company, Horizon Services LLC. The new office is the first example of Horizon’s financial resources and additional personnel, and will support Casteel’s goal to deepen and broaden customer relationships.

Casteel is one of the largest service businesses in the Atlanta market with over 25 percent year-on-year growth since 2012.

“Opening an office on the east side of Atlanta is exciting for us,” says Gary Obert, Jr., Operations Manager for Casteel. “We have been working on expanding our presence in Atlanta to fulfill our ‘Amazing Care Guarantee,’” Obert continues, “Our newest location brings our honest, customer-focused care to more area homeowners.”
