03

Quote Before Work

Written quote with options — repair, replace, or both. You decide. Financing available on installs from approximately $68/month OAC.

04

Done Properly

Permit-pulled when required. ESA/TSSA inspected. Cleaned up after. Followed up to confirm everything is running the way it should.

About MS Heating & Cooling

A small local business, built on word of mouth.

MS Heating & Cooling is a licensed HVAC contractor based at 600 Granite Court in Pickering, Ontario. We focus on residential heating and cooling — furnaces, air conditioners, hot water tanks, tankless water heaters, and gas line work — across Durham Region and east Toronto. We're authorized installers for Lennox and York, and we service every major brand including Carrier, Goodman, Trane, Bryant, Navien, Rinnai, and Bradford White.

The reason we're 5.0 stars on Google with 66+ reviews isn't marketing. It's that we treat every house like it's our own: properly sized equipment, clean installs, fair quotes, honest answers. When something's a repair, we say so. When it's a replacement, we say that too.

We're not the biggest HVAC company in Durham. We're a small, focused operation that picks up the phone, shows up when we say we will, and leaves your house cleaner than we found it.

Tankless install went smoothly — venting was tricky but they figured it out. Endless hot water now and the gas bill is actually lower. Would call them back without hesitation.

Same-day response is standard for emergencies in Pickering, Ajax, and Whitby. Call (905) 410-2886 directly — we will give you a realistic arrival window before dispatching, not a vague "sometime today" promise. Most no-heat and no-cooling issues are diagnosed within the first hour on site.
We install Lennox and York high-efficiency furnaces. Both brands offer reliable performance for Ontario winters, strong manufacturer warranties, and good parts availability.

Tankless water heaters offer endless hot water, lower energy bills, longer lifespan (15–20 years vs 8–12), and a much smaller footprint — but cost more upfront and require properly sized gas and venting. Traditional hot water tanks have a lower install cost and simpler maintenance. We help you choose based on your home size, hot water demand, fuel type, and budget. Both options are available with Financeit financing from approximately $68/month OAC.
