We Are The Home Comfort People*?
Who Service What We Sell!

 JJ McLellan & Son has been in business for over
70 years and through 4 generations! 

In 1948 Hap took over the “McLellan Plumbing” business from his father Ross at the age of 17. He later in 1959 incorporated the business as JJ McLellan & Son Ltd., naming the business after his grandfather, John J. McLellan. In 1966, JJ McLellan & Son adopted their slogan, “The Home Comfort People”. JJ McLellan & Son became a member of the Union Gas Dealer Association in the 1960’s. This affiliation provided increased product and service offerings to JJ customers.

Jamie McLellan, Hap & Mary’s son, started working in the plumbing and heating business in 1971 and eventually assumed the lead in 1990. In 1993, Jamie became the president of JJ McLellan & Son operated by Hap McLellan Ltd. Today JJ McLellan & Son’s business of mechanical contracting includes the full breadth of plumbing and heating sales, service and both residential and commercial installations. The company has been an independent Lennox dealer for over 60 years.
