Welcome to Nadeau's

Nadeau’s Refrigeration was started in 1978, owner Ron Nadeau had worked in the refrigeration industry for a decade when he decided it was time he started his own business. He traveled all over the state servicing cooling systems from giant systems at the paper mills to individual units in people’s homes. After six months of working in his garage, Ron Nadeau rented a warehouse on Stanley Street. It was another year before he hired his first employee. By the early 1980’s, Nadeau’s had five employees.

In July of 2012, Paul Gardner purchased Nadeau’s Refrigeration from the Nadeau family. A native of Lewiston-Auburn, Paul brings over 30 years of HVAC/R experience to the company.

Over the years Nadeau’s has expanded in a number of directions; including Heating, Air Conditioning, Refrigeration and Plumbing. Our client base has steadily grown due to our dedicated employees; most of whom have been with Nadeau’s long term. Nadeau’s strives to provide our customers with the best possible service and is continually training our employees to keep up with all the changes in the HVAC/R and plumbing industry.
