The Jerry Kelly Heating, Air Conditioning, Electrical and Plumbing Legacy

1977

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 of HVAC contractors forged a tradition that stands to this day: “We don’t just ‘say’ 24-hour service. We follow through.”
