Customized comfort for every room in your home with a multi-zone wall-mounted heat pump
At AirGreen, we know that every home is unique—just like the comfort needs of those who live there. When it comes time to choose a heating and cooling solution that’s efficient, long-lasting, and adaptable, the multi-zone wall-mounted heat pump stands out as an essential option. Especially in regions with harsh climate fluctuations like Montréal, Laval, Longueuil, the North Shore, and the South Shore, this system provides unmatched flexibility while delivering substantial energy savings.
Understanding the multi-zone system: how does it work?
A multi-zone wall-mounted heat pump consists of a single outdoor unit connected to multiple indoor wall-mounted units. Each indoor head is installed in a separate room, allowing for independent temperature control in each zone. Unlike a single-zone unit, this system adapts to the specific needs of every area in the home.
For example, a bedroom can stay cooler at night while the living room remains comfortably heated during the day. This zoned control maximizes both comfort and energy performance.
Why choose a multi-zone wall-mounted heat pump?
Here are some of the key advantages of this type of system:
-
Total flexibility: Adjust the temperature of each room independently.
-
High energy efficiency: Avoid unnecessary consumption with room-by-room control.
-
Sleek aesthetics: Modern wall units are compact and discreet.
-
Less outdoor clutter: A single outdoor unit supports multiple zones.
-
Simplified installation: Requires fewer renovations than central ducted systems.
Case study: Multi-zone installation in Laval with a Gree Multi+ heat pump
In a single-family home located in Laval, our certified technicians recently installed a Gree Multi+ 36,000 BTU wall-mounted heat pump, with three indoor units placed in the living room, master bedroom, and basement. The clients chose this solution because they didn’t want to install ductwork inside their walls but still wanted optimal comfort throughout the home.
Challenges encountered:
-
Access to the basement required drilling through a 10-inch concrete foundation.
-
The wiring between the indoor and outdoor units ran near natural gas piping.
Solutions provided by AirGreen:
-
Used a water-cooled core drill for a clean and safe hole.
-
Carefully insulated electrical wiring with certified sheathing to avoid interference with existing utilities.
Results:
-
A 40% reduction in the electricity bill.
-
Constant comfort across all zones, even during harsh winter cold snaps.
