HVAC Service Rooted in Keswick, on the Shores of Lake Simcoe
From our shop at 24201 Woodbine Ave, our family-run team keeps Keswick and the surrounding York Region communities comfortable year-round, through lake-effect cold snaps, humid summer afternoons, and every kind of day Ontario's climate sends our way.
A Woodbine Avenue Shop Serving the Community We Call Home
Keswick Heating & Cooling is a family-run HVAC company built on a simple belief: treat every home like it's our own, whether it's a year-round residence near the lakeshore, a converted cottage, or a newer build in the subdivisions pushing north off Woodbine Avenue.
Keswick sits on Cook's Bay at the south end of Lake Simcoe, and that geography shapes how we heat and cool homes here. When the lake freezes over, the cold coming off the ice is a different beast entirely, and lake-effect snow pushing down from Georgian Bay can bury a street in hours. Our winters demand furnaces that are properly sized and maintained for real deep-freeze conditions, not mild Ontario averages.
Summer flips the script. The same lake that freezes solid in January holds humidity well into August, and homes near the shoreline feel stickier than properties even a few kilometres inland. We tune air conditioners and ductless systems to strip out moisture as well as heat, because dry, cool air is what actually makes a lakeshore home comfortable on a 30-degree afternoon.
Because so much of Keswick grew up as cottage country before becoming a year-round community, we work on a wider mix of housing stock than most HVAC companies. Original cottages with undersized ductwork, ranch-style homes from the 70s and 80s, and modern builds all call for different approaches, and we carry the parts and the experience to handle all of it.
Local Knowledge That Earns Its Keep
A furnace sized for a tight new subdivision won't keep up in a drafty lakeshore cottage, and a one-size-fits-all air conditioner won't handle a humid Cook's Bay afternoon. We size and tune every system to your actual home and your actual spot on the map, so it runs efficiently, lasts longer, and keeps every room comfortable.
Honest Service Across Keswick and Northern York Region
Our licensed, insured technicians install and service the full range of home comfort equipment: high-efficiency furnaces, central and ductless air conditioning, cold-climate heat pumps, smart thermostats, fireplace installations, and complete duct cleaning. We serve Keswick and the surrounding York Region communities, including Markham, Richmond Hill, Newmarket, Aurora, Vaughan, Stouffville, and King City.
Being based on Woodbine Avenue means most of our calls are a short drive away, which matters when your furnace quits on a -20 morning or your AC fails during a humid lakeshore stretch. You get faster response times and technicians who already understand the quirks of local housing stock, and every visit starts with honest diagnostics and a transparent quote before any work begins.
