Company History

Since 1955 Joval has enjoyed serving a very loyal customer base that values quality, consistency, and personal service. Joval was founded by partners John Valenza and Walter Johnson, who combined their last names to come up with the company name.

John Valenza had been working with Walter Johnson in 20th Century Sheet Metal, a company that they started by kicking John’s father’s mule out of the barn. As that company grew in the commercial HVAC market, John’s brothers joined the company. Eventually, John and Walter left that company to start Joval, which would introduce pre-fab metal duct and fittings to the growing residential market in Louisiana and Mississippi. They built the plant in Jefferson Parish, near the Orleans Parish line on Iris Ave. The plant remains in that location today, although it has had many expansions over the years.

John Valenza, Jr. joined the company in the mid 1970’s and fulfilled various roles in management. He eventually succeeded his father as President of Joval and remains in that position today.

Under the current ownership of John Jr , along with his two sons John III and Jason,  Joval remains a Louisiana based, family owned, homegrown company. Joval is currently focused on expanding into new product lines and improving aspects of existing products. The motto for Joval is “Manufacturing, Delivering, Growing”. This reminds us of our commitment to manufacture top quality products, delivering excellent customer service, and growing to meet our customers’ needs.
