A radical transformation of indoor comfort in a Montréal condo
When it comes to comfort inside a condo located in the heart of Montréal, wall-mounted air conditioning units are often the first solution people consider. They’re easy to install and serve a purpose. But for many of our clients—like the one featured in this testimonial—those systems just don’t cut it anymore after experiencing a ducted system installed by AirGreen.
This story takes place in a spacious apartment in Rosemont–La Petite-Patrie, where we completely transformed the HVAC experience for a young professional couple tired of the aesthetic and acoustic compromises of wall units. They reached out to us through our personalized ducted system design and installation service, looking for a solution that would be invisible, silent, and above all, offer even air distribution.
What our clients were looking for: discretion, silence, and performance
The couple had three clear priorities:
-
Eliminate bulky wall-mounted units that disrupted the visual harmony of their home.
-
Reduce the operational noise from the old systems that was becoming increasingly disruptive at night.
-
Enjoy uniform comfort in every room—no cold zones or overheated spots.
After a detailed assessment of their space, we recommended a centralized ducted system, ceiling-integrated, powered by a GREE GMV Slim Duct indoor unit, paired with an outdoor GREE Multi-Ultra heat pump, known for its high energy efficiency and compatibility with compact residential setups typical of Montréal.
Technical details of the HVAC installation
The installation revolved around a low-profile ducted indoor unit, specifically designed to fit discreetly into the hallway’s drop ceiling. Here are the details of the system we implemented:
-
Brand and model: GREE GMV Slim Duct 24,000 BTU
-
Outdoor heat pump: GREE Multi-Ultra 36,000 BTU – Inverter
-
Energy efficiency: SEER 20, HSPF 10.5
-
Compatibility: Multi-zone system with smart zone-based controls (wall thermostats)
-
Grant eligibility: Eligible for the Hydro-Québec LogisVert Grant, with an estimated rebate of $1,860
This system is virtually invisible to the naked eye, aside from the small ventilation grilles carefully aligned with the condo’s architectural design. Everything is controlled via smart thermostats that automatically adjust temperature based on time of day and room usage.
Challenges encountered and tailored solutions
The biggest challenge in this project was integrating the ducts into a tight space, with 8-foot ceilings and some parts of the structure made of concrete. So we:
-
Modified certain ceiling segments using decorative hollow beams to hide the ductwork.
-
Worked in coordination with an interior designer to maintain a seamless aesthetic.
-
Planned the installation in two phases to minimize disruption to the couple’s daily life.
This meticulous approach is what sets AirGreen apart—we tailor every HVAC installation to fit our client’s physical space, while ensuring optimal system performance.
The results after installation
Just a few weeks after the system was activated, our clients shared their feedback:
“We felt the difference the very first night. No vibrations, no noise… We finally slept in absolute comfort. Not seeing wall units everywhere really changed the way we interact with the space.”
The ducted system helped reduce their electricity bill by nearly 20%, while also increasing the perceived value of their condo. They’re even considering selling in the near future, knowing this installation is a major asset on the Montréal real estate market.
Why choose a ducted system instead of a wall-mounted heat pump?
Here are some real-world advantages observed in this project:
-
Superior aesthetics: no visible equipment at all.
-
Consistent comfort: even temperatures with no drafts.
-
Total silence: whisper-quiet operation.
-
Smart control: room-by-room temperature management.
-
High energy efficiency: ideal for urban areas like Montréal.
At AirGreen, we believe that every space deserves a custom HVAC solution, tailored not only to the dimensions and technical constraints, but also to the lifestyle of its occupants. Our teams are trained to work in complex environments, including renovation projects, heritage buildings, and modern condos.
Practical tips before switching to ducted
For those considering a similar upgrade, here are a few key points to keep in mind:
-
Evaluate your ceiling height: you’ll need at least 10 to 12 inches to accommodate ductwork.
-
Think about which zones to cool or heat: each zone can have its own thermostat.
-
Check available grants: ducted systems are often eligible for financial assistance programs.
-
Work with a certified installer like AirGreen: our expertise ensures maximum efficiency and long-term durability.
