Four-season comfort in a sunroom thanks to expert installation by AirGreen
In the quiet neighborhood of Rosemont–La Petite-Patrie, Montréal, a couple passionate about nature and natural light transformed part of their home into a beautiful four-season sunroom. However, this sun-soaked space posed a real challenge when it came to maintaining a stable indoor temperature, both in winter and summer. After extensive research and recommendations, they chose to contact AirGreen, experts in custom HVAC solutions throughout Montréal, Laval, Longueuil, North Shore and South Shore.
A typical challenge: heating and cooling a glass-enclosed room
Sunrooms present specific challenges that make climate control complex:
-
Lower thermal insulation compared to solid walls.
-
Direct sun exposure leading to overheating in the summer.
-
Significant heat loss during the winter months.
-
A need for a discreet, aesthetic system that blends in harmoniously.
The couple wanted to preserve the minimalist, clean look of the room while ensuring consistent year-round comfort.
Our recommendation: a compact, powerful, and discreet floor-mounted console
After a thorough assessment of the sunroom’s layout, orientation, and energy needs, we recommended installing a floor-mounted wall console, also known as a floor-ceiling indoor unit. This type of unit is especially well-suited for rooms with large glass surfaces, where traditional wall-mounted units lose efficiency.
Chosen model: Fujitsu RLS2CV Console – 12,000 BTU
-
Renowned brand: Fujitsu, a global HVAC leader.
-
Capacity: 12,000 BTU, ideal for this 22 m² space.
-
Energy efficiency: SEER 20 / HSPF 10.5.
-
Inverter technology: allows for precise temperature adjustments and reduced energy use.
-
Floor heating mode: gently distributes warm air from the bottom, mimicking the comfort of radiant heat.
Installation steps and challenges overcome
Environmental analysis
We started with a comprehensive thermal assessment of the sunroom, taking into account heat loss coefficients, the materials used (double glazing, polycarbonate roofing), and how the space is used day to day.
Choosing the ideal location
Wall space was limited below the glass panels. After multiple simulations, we integrated the console into a discreet corner, under the shortest glass section, ensuring optimal air distribution without obstructing the view.
Drilling through the slab and wall penetration
The console required a core drilling through the foundation for the refrigerant line, which posed sealing and insulation challenges. Leveraging our expertise, we used a custom insulated sleeve with freeze protection and urethane sealing.
Installation of the outdoor unit
The Fujitsu outdoor unit was installed on an anti-vibration wall bracket, raised high enough to prevent snow accumulation and allow easy maintenance access.
The result: a comfortable, quiet, and energy-efficient sunroom
The couple immediately noticed the difference. Temperature remains stable, even during the harshest cold snaps in January or scorching days in July. The unit is virtually silent, and its matte white finish blends in perfectly with the wood finishes in the space.
“We were impressed by the precision of the installation. Nothing was left to chance. The console is efficient, elegant, and doesn’t take away from the look of our sunroom. Thank you to the entire AirGreen team!”

Why choose a floor console for a sunroom?
Floor-mounted consoles are a smart alternative to traditional wall-mounted units or portable ACs:
-
Ideal for glass-heavy or hard-to-use walls.
-
Air is distributed at human height, perfect for rooms with high ceilings.
-
Easy to maintain, with front-access filters.
-
Offer better thermal distribution, especially for open-concept or complex-shaped spaces.
AirGreen: HVAC solutions tailored to every room
At AirGreen, we don’t believe in one-size-fits-all. Every installation is based on a personalized assessment:
-
Heat load calculations.
-
Selection of the most suitable unit (wall-mounted, central, cassette, console…).
-
Integration that respects the space’s design.
-
Strict compliance with electrical and ventilation standards.
Available grants for this type of installation
Although consoles aren’t always covered by major grant programs, some local subsidies or energy-efficiency incentives may apply:
-
Rénoclimat Program (eligibility conditions apply).
-
Municipal energy-efficiency aid (varies by borough).
-
Green renovation tax credits.
Our team helps each client verify their eligibility, fill out the paperwork, and submit all required documentation.
The importance of maintenance
A properly installed floor console can last over 15 years, but annual HVAC maintenance is crucial to keep it running efficiently:
-
Filter cleaning.
-
Condensate drainage check.
-
Refrigerant pressure test.
-
Electrical connection inspection.
We offer custom HVAC maintenance plans, including automatic reminders, full technical inspections, and personalized advice.
Conclusion: a successful installation in a demanding architectural setting
This installation of a 12,000 BTU Fujitsu floor console in a residential sunroom in Montréal is a perfect example of our expertise: delivering custom HVAC solutions that are efficient and long-lasting, while meeting both technical and aesthetic needs.
