The Jerry Kelly Legacy

After working in the heating and cooling business for 12 years, Jerry Kelly and his wife, Janet, opened Jerry Kelly Heating & Air Conditioning in 1977. They started Jerry Kelly Heating & Air Conditioning in a white and green brick building in the historic Frenchtown district of St. Charles, MO. With five technicians and a few used trucks, Jerry and his team forged a tradition that stands to this day: “We don’t just ‘say’ 24-hour service. We follow through.”

The headquarters for Jerry Kelly Heating & Air Conditioning now resides in St. Peters, MO, where the company services over 50,000 customers!
