Services We Provide in Markham
From older Unionville homes to newer Cornell builds — full-service HVAC for all of Markham's diverse housing stock.
Furnace Installation & Repair
Markham's wide range of homes — from Unionville's 1970s–80s stock to Cornell's newer builds — means varied equipment needs. We install 80% and 96% AFUE furnaces for every type of home and offer same-day emergency repair.
Air Conditioning & Heat Pumps
Markham's newer Cornell and Cathedraltown neighbourhoods are well-suited for cold-climate heat pump upgrades. We size every system properly — CSA F280 heat-loss and heat-gain calculation, not guesswork — for your home's specific configuration.
Boiler Repair & Water Heaters
Older Unionville and Markham Village properties often have original hot-water boiler systems. We repair and replace all major boiler brands, and install tankless water heaters for older Markham homes upgrading their domestic hot water.
