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
