McKenney Mechanical was founded in 1987 as a piping contractor. Our first project was the completion of the Mechanical Contract for the Novo Laboratories project in Danbury, CT. As our company grew we evolved into a full service mechanical contractor to better service our customers' needs. We are able to offer the building owner or the plant operator anything they may need to operate their facility. The Service Division is headed by Jeff Giannaccio and offers the building owner or operator the following services: HVAC sales, installation, repair, temperature controls, service contracts and plumbing repairs.
