Optimizing comfort in your Montréal condo with the right type of indoor HVAC unit
When the time comes to choose a cooling or heating solution for a condo in Montréal, the options are plenty. But not all are suited to the unique architecture, interior design, or energy requirements of a downtown condo. At AirGreen, we know that choosing the right indoor HVAC unit can completely transform a living space—both in terms of thermal comfort and energy performance.
Here’s a comprehensive guide to help you understand the different types of indoor units available: wall-mounted air conditioner, ceiling cassette, floor console, floor-ceiling unit, and ducted system, and how suitable each is for your condo in Montréal, Laval, Longueuil, the North Shore, or the South Shore.
The unique thermal and architectural aspects of condos in Montréal
Condos in Greater Montréal come with unique challenges: limited floor space, varied ceiling heights, sun-exposed windows, or restrictions from condo boards (limited outdoor unit space, soundproofing, façade appearance).
These factors make it even more critical to select an indoor unit that fits well. A poor configuration can lead to efficiency loss, unwanted noise, or higher maintenance costs.
1. Wall-mounted air conditioner: discreet and versatile
This is by far the most commonly installed unit in condos. Mounted high on a wall, it allows for optimal airflow without taking up floor space.
Advantages:
-
Quick, low-impact installation.
-
Perfect for small to medium-sized spaces.
-
Compatible with multi-zone systems.
-
Easy to access for HVAC maintenance.
Disadvantages:
-
Visible (less discreet than other options).
-
The aesthetic may not suit every interior.
Ideal for:
One- or two-bedroom condos in central Montréal, Longueuil, or on the South Shore, where people are looking for a quick, affordable, and efficient solution.
2. Ceiling cassette: sleek, recessed option for suspended ceilings
If your condo has a suspended or drop ceiling, the ceiling cassette is a great option. It integrates directly into the ceiling and distributes air in multiple directions.
Advantages:
-
Completely aesthetically discreet.
-
360° air diffusion: even temperature throughout the space.
-
Perfect for open-concept spaces.
Disadvantages:
-
More complex installation (requires proper ceiling structure).
-
Less accessible for maintenance.
Ideal for:
High-end condos located in Ville-Marie, Griffintown, or even on the North Shore, where interior design is just as important as performance.
3. Floor console: the modern radiator of HVAC
Much like a traditional radiator, the floor console is installed low on the wall. It's ideal for spaces with large windows or limited wall height.
Advantages:
-
Effectively replaces old electric baseboards.
-
Provides gentle heat distribution near the floor.
-
Easy to access for servicing.
Disadvantages:
-
Takes up floor space.
-
Less suited for large areas.
Ideal for:
Ground-floor condos in Hochelaga, Saint-Léonard, or on the South Shore, with large windows or walls too cluttered for a wall unit.
4. Floor-ceiling unit: the definition of flexibility
This unique unit can be installed near the floor or high on the wall, all while maintaining a compact and high-performing design.
Advantages:
-
Flexible installation.
-
A good compromise between floor console and ceiling cassette.
-
High airflow volume for larger spaces.
Disadvantages:
-
More expensive than other models.
-
The design may not appeal to everyone.
Ideal for:
Condos with tall ceilings in the Old Port, Outremont, or newer developments on the North Shore like Boisbriand or Blainville.
5. Ducted system: the ultimate invisible solution
This is the most high-end and discreet option: no visible unit, just minimalist vents for air distribution.
Advantages:
-
Flawless aesthetics.
-
Even, consistent comfort.
-
Extremely quiet.
Disadvantages:
-
Higher cost.
-
Heavier installation work.
-
Requires space for the duct network.
Ideal for:
New or fully renovated condos with open floor plans, often found in Westmount, Outremont, or converted industrial lofts in the Plateau.
