Compact and Efficient HVAC Solutions for Urban Apartments in Montreal
In a context where space has become a rare commodity in Montreal apartments, choosing a compact, quiet, and efficient multi-zone heat pump is a major concern. Whether you're in the Plateau, Griffintown, Outremont, or in dense areas like Côte-des-Neiges or Vieux-Rosemont, property owners and building managers are seeking HVAC solutions that combine comfort, energy efficiency, and discretion.
At AirGreen, we install multi-zone systems daily in apartments and condos of all sizes across Montreal, Laval, Longueuil, as well as the North Shore and South Shore, focusing on the most suitable models for urban living: discreet, reliable, easy to integrate, and eligible for Hydro-Québec’s LogisVert grants.
Why Choose a Compact Multi-Zone Heat Pump in Montreal?
Maximizing Space is Essential
In Montreal housing, especially in condos and apartments built before the 2000s, interior space is often limited. Installing multiple wall units or a central ducted system can be complex—or even impossible. Compact multi-zone heat pumps offer an ideal solution: a single outdoor compressor powers several indoor units — wall-mounted, console, or ceiling-mounted — allowing you to heat and cool multiple rooms without sacrificing living space.
Reduced Noise Pollution
New-generation compact multi-zone systems are designed to operate ultra quietly. This is a major advantage in urban settings where noise pollution is a real concern. Our downtown Montreal clients consistently report satisfaction with the low noise level of their system, both indoors and outdoors.

Testimonial from a Client in Verdun
"AirGreen recommended an ultra-discreet Fujitsu multi-zone heat pump. We had very little outdoor space and no balcony. Their team found the perfect spot for the outdoor unit, without affecting the building's appearance. The installation was quick and clean. Since then, we sleep cool and in peace!"
— Julie P., condo owner
