HVAC Smart Solution serves all of Markham — Unionville, Cornell, Markham Village, and Cathedraltown — from our Thornhill base. Furnace, AC, heat pump, boiler, and 24/7 emergency HVAC service. TSSA-licensed.
From older Unionville homes to newer Cornell builds — full-service HVAC for all of Markham's diverse housing stock.
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.
Markham's newer Cornell and Cathedraltown neighbourhoods are well-suited for cold-climate heat pump upgrades. We size every system properly — Manual J load calculation, not guesswork — for your home's specific configuration.
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.
Fast access from Thornhill, deep familiarity with Markham's housing stock, and a consistent 5-star reputation across York Region.
Our Thornhill office puts us 20–25 minutes from most Markham neighbourhoods via Highway 7 or the 407. Same-day service and emergency response available across all of Markham, from Milliken to Stouffville Road.
Markham has one of the most diverse housing stocks in the GTA — heritage homes in Unionville, older subdivisions in Milliken, and large modern builds in Cornell and Cathedraltown. We've worked across the full range and know how to size equipment correctly for each type.
