A well-designed ventilation system in a Montréal condo is far from a luxury—it’s an absolute necessity. And yet, too many homeowners only discover the consequences of poor ventilation when it’s already too late: humidity problems, poor air quality, thermal discomfort, even mold. At AirGreen, we specialize in custom HVAC solutions for condos of all sizes in Montréal, Laval, Longueuil, the North Shore and the South Shore, with technical expertise that goes beyond expectations and anticipates the unique challenges of high-rise residential buildings.
Why Condo Ventilation Can’t Be Treated Like That of a House
In a condo, space is tighter, systems are often interconnected, and air pressure is influenced by elevators, shared walls, and low ceilings. A poorly calibrated ventilation system can affect multiple units, lower indoor air quality, and reduce the building’s overall energy efficiency.
Common Issues We Encounter:
-
Moisture buildup in bathrooms and kitchens without proper exhaust
-
Odors traveling between units due to poorly designed ductwork
-
Infiltration of unfiltered outdoor air
-
Thermal discomfort in winter or summer
That’s where our expertise comes in. Every residential condo building has its own architectural constraints, and we know how to analyze them with precision.
Case Study: A Recent Installation in a Condo in Plateau-Mont-Royal
A client, owner of a high-end condo in a 2000s-era building on Mont-Royal Avenue, contacted us after noticing unusually high humidity levels in their bathroom, despite having a standard exhaust fan.
What We Found:
-
The existing fan wasn’t connected to ducting that led outdoors, causing humid air to accumulate in the suspended ceiling.
-
The kitchen ventilation system was simply recirculating air, with no exhaust.
-
The existing HRV (heat recovery ventilator) was undersized for the livable space.
Our Solutions:
We proposed a complete ventilation overhaul for the condo in three steps:
-
Installation of a Venmar EVO5 700 HRV system, compact yet powerful, specifically suited for condos.
-
Independent ducting to the outdoors for the bathroom, with a Fantech fan rated for small residential units.
-
Installation of transfer grilles to promote air circulation between rooms, while maintaining soundproofing.
The entire project was completed in two days, with minimal disturbance to neighbors, and most importantly, without major modifications to the suspended ceiling, thanks to our extensive experience in tight-space renovations.
What No One Tells You (Until It’s Too Late)
The majority of ventilation systems in condos are installed according to bare minimum standards set by developers. This means:
-
Inadequate power
-
Poor energy efficiency
-
Excessive noise
-
Difficult or impossible maintenance
And this often leads to a scenario we see all too frequently: ventilation is ignored until the problems become visible—or expensive.
