A family beginning

Fernand Denis is a family-owned heating and air conditioning company with nearly 50 years of satisfied customers in Glengarry and Prescott and Russell. It all began in 1976 when Fernand saw an opportunity. At that time, it was a home-based business in Saint-Isidore with a single truck. While his wife, Françoise, handled the administrative side of things, he went door-to-door repairing and maintaining furnaces. In 1983, Fernand obtained his propane license and hired his first full-time employee. Shortly after, a second truck was added, and the business quickly grew to four employees.

Becoming a local leader

In 1991, the company underwent another expansion when a full office and retail store were built in Saint-Isidore. In 1996, Fernand's sons, Pascal and Patrick, joined the company. Today, Fernand Denis has over 30 employees and is the leader in the heating and air conditioning industry in Glengarry and Prescott and Russell. With hundreds of satisfied customers, Fernand Denis is also the first choice of homeowners and builders in Saint-Isidore, Casselman, Embrun, Alexandria, Clarence-Rockland, Hawkesbury, and throughout the region.
