In 1979, after eleven years of dedicated service working for another leading air conditioning company, David Dupuis embarked upon a business journey and opened his own full-time business. This one-man company started in his home in Henderson, Louisiana. It steadily outgrew the home office and branched out into a warehouse of its own.

In 1994, David built Dupuis Heating & Air Conditioning at its new location in the heart of Henderson, LA at 1382 Henderson Hwy. Today, Dupuis Heating & Air Conditioning is a booming multi-crew business that boasts quality service and reliable equipment. David's strong work ethic, dedication to quality service, and reliability has kept his company going strong for 34 years. And as time marched on, the Dupuis legacy continued. In 2007 David Dupuis Jr joined forces with his father to carry on the family owned business.

Today both men have numerous credentials that qualify them to proudly serve the Acadiana area. David Dupuis Sr is a member of the Louisiana Heat Pump Association, Acadiana Chapter.

Throughout the duration of his membership, he expanded upon his responsibilities by becoming a board member for many years, and later President. David Jr has followed in his father's footsteps by also becoming a member of the Louisiana Heat Pump Association. He has been a board member for 4 years, and served as President in 2012. In addition to their personal achievements, the company has received numerous awards for the excellent work they perform. They look forward to earning many more in the future.
