Unionville Heating and Air Conditioning is proud to receive Readers’ Choice 2025 Diamond Winner recognition in both Markham and Stouffville. The Diamond award represents the top tier of the Readers’ Choice program, and winning in two communities in the same year is a reflection of the trust our customers place in us every day.
In November 2025, Unionville Heating was also recognized as a 2025 Community Votes Platinum Winner in Markham — two separate awards programs, both reflecting the same community confidence.
41 Years, Two Communities, One Standard of Service
This year also marks Unionville Heating’s 41st anniversary — a milestone engraved right on the awards themselves. Since 1985, the company has served residential customers in Markham, Unionville, and Stouffville with the same commitment to quality that earned these recognitions today.
Owner John St. Germain and his team of service technicians are grateful for every nomination and vote that made these awards possible.
