Since 2008, Northside Heating & Cooling has been the GTA's go-to team for furnace installs, AC replacements, and emergency repairs. We're not the biggest company in Toronto — and that's the point.
When you call us, you talk to someone who knows your system, knows your neighbourhood, and gets the job done right the first time.
From emergency furnace repairs at midnight to full heat pump installations — our licensed technicians handle it all.

Our furnace went out on a Friday night in January. Northside had a tech at our door by 9am Saturday. Fixed in two hours, fair price. These guys are the real deal.
I've been using Northside for three years for our annual tune-ups. They're always on time, always explain what they're doing, and never try to upsell you on things you don't need. Rare to find that.
Had three quotes for a new heat pump. Northside came in the middle but gave me the most detailed explanation of what they were installing and why. Zero regrets — it's been running perfectly since October.
