A dual-purpose HVAC solution for optimal comfort in challenging spaces
In a market like HVAC in Montréal, where interior design constraints can quickly become a headache, the floor-ceiling unit stands out as an ingenious, elegant, and high-performance solution. At AirGreen, we’re seeing increasing demand for this type of indoor unit, particularly in upscale residential properties, retail stores, and offices where the layout doesn’t allow for wall-mounted or traditional console units.
In this article, we’ll share our on-the-ground expertise with this versatile solution, its technical advantages, typical installation challenges in the Montréal, Laval, Longueuil, and North and South Shore areas, along with real-life examples of projects completed by our teams.
What is a floor-ceiling unit?
The floor-ceiling unit, also known as a "vertical/horizontal console," is an indoor component of a multi-zone heat pump system or a central air conditioner. Its main feature is its flexibility in installation: it can be installed low on a wall (like a console) or suspended from the ceiling, similar to a ductless system without needing a drop ceiling.
Why do we call it the "chameleon" of HVAC?
Because it adapts to architectural constraints: low ceilings, cluttered walls, open-plan rooms, and more. It ensures even air distribution, whether heating or cooling, without compromising aesthetics or space functionality.
The technical advantages of the floor-ceiling unit
Controlled air distribution
Thanks to a powerful, multidirectional airflow system, the air is blown either horizontally or vertically depending on the unit's position, enabling fast and even heating or cooling of large areas.
A perfect fit for renovations and heritage buildings
In Montréal and the South Shore, we often work in older or heritage-protected buildings where installing ducts or wall units is simply not feasible. The floor-ceiling unit offers a way to avoid invasive renovation work while providing modern energy performance.
Discreet and stylish
Non-intrusive, it blends in easily with the environment—whether mounted high in a commercial setting or used as a console in a modern living room. It won’t block windows or take up valuable wall space.
Brands and models we install at AirGreen

Eligible for government grants
Many of these models are eligible for rebates through Hydro-Québec’s LogisVert program, especially when replacing fossil fuel systems with heat pumps.
Case study: Floor-ceiling unit installation in Laval
The context
A high-end clothing boutique in Laval, located in a retail space with large display windows, a concrete ceiling, and no suspended ceiling. The client wanted a discreet yet powerful cooling system for their 1,200 sq. ft. shop.
AirGreen’s recommendation
We proposed installing two 18,000 BTU Fujitsu floor-ceiling units, mounted high at either end of the space, connected to a dual-zone outdoor unit. This system allowed the client to keep their wall space free for merchandise and maintain a smooth customer flow throughout the store.
The challenges
-
Drilling through reinforced concrete for the refrigerant lines
-
Calibrating the airflow angles to prevent drafts on customers
-
High-level installation without scaffolding (we used mobile ladders)
The result
A system that’s efficient, silent, and visually integrated, installed in just two days, and a very satisfied client.
What to know before choosing a floor-ceiling unit
A thermal assessment is essential
To avoid oversizing or undersizing the system, we always conduct a personalized thermal analysis, taking into account sun exposure, insulation, and room usage.
Minimum ceiling clearance required
Even in floor mode, the unit needs enough clearance for proper airflow. In ceiling mode, you’ll need about 12 inches (30 cm) of vertical space.
Easy maintenance
Unlike some wall units, these models are easy to clean, even when installed high up, thanks to removable front panels.
