What’s the Best HVAC System for Montreal Weather?

🍁 Introduction

Montreal weather isn’t just cold — it’s brutal in winter and humid in summer. Your HVAC system must handle -25°C frost and 30°C heatwaves with high humidity. So, what’s the best system setup?

Here’s our expert recommendation based on local experience.

❄️ Winters: You Need Reliable Heating

Option 1: Cold-Climate Heat Pump

• Works efficiently even in extreme cold
• Energy efficient and government rebate-friendly
• Can be paired with a backup electric or gas furnace

Option 2: Dual-Fuel System (Hybrid)

• Heat pump handles mild to moderate cold
• Gas furnace kicks in during extreme cold
• Best balance between cost and reliability

🌡️ Summers: Humidity is the Real Enemy

• High humidity can make your home feel hotter than it is
• Central air conditioners or ductless AC units with dehumidification function are essential
• Systems with variable speed compressors help maintain comfort without overcooling

🏠 For Older Montreal Homes

• No existing ductwork? Go for ductless mini-split heat pumps
• High efficiency, room-by-room control, low installation disruption
• Quiet and aesthetic indoor units
