Why Your Bathroom in Longueuil Should Never Be Without Professional Ventilation

An invisible yet essential element for your bathroom’s comfort

At AirGreen, we’ve seen time and again that one of the most overlooked issues in residential projects in Longueuil, especially during bathroom renovations or new builds, is the absence or inadequacy of a professional ventilation system. And yet, a properly ventilated bathroom is critical for air quality, material durability, mold prevention, and even your property value.

Our expertise in installing HVAC ventilation systems in Longueuil, on the South Shore, and throughout Greater Montréal, has brought us into many homes where poor ventilation caused invisible but costly damage. This article dives into why a professional bathroom ventilation system is essential, how we handle it at AirGreen, and what concrete benefits it brings you.

Humidity: the silent enemy of your bathroom

The bathroom is undoubtedly the most humid room in your home. Every hot shower, every bath, every use of the sink releases a significant amount of water vapor. Without proper ventilation, this humidity:

• Accumulates on walls and ceilings, damaging paint, plaster, and materials.

• Promotes mold and mildew growth, often invisible at first, but hazardous to health.

• Damages wood structures, tile joints, cabinets, and even electrical installations over time.

• Increases condensation on windows and mirrors, shortening their lifespan.

Why a simple window isn’t enough

Many homes in Longueuil and across the South Shore still rely on a small bathroom window as their sole ventilation system. While this solution may have been acceptable in the past, it is now woefully insufficient:

• Opening a window is often impractical during winter.

• It doesn’t effectively extract moisture from corners and hard-to-reach spots.

• It doesn’t filter or properly renew the air.

Controlled mechanical ventilation: an effective and lasting solution

At AirGreen, we always recommend installing a controlled mechanical ventilation (CMV) system for bathrooms. Our installations are designed to offer:

• Fast and silent extraction of humid air.

• Calibrated airflow based on your bathroom’s size.

• Low energy consumption with high-efficiency ECM motor fans.

• Minimal maintenance, with easily replaceable filters.

Case study: installing an ultra-quiet bathroom fan in Longueuil

In a recent project in the Saint-Hubert neighborhood of Longueuil, we were contacted by a family living in a 1970s bungalow. Their bathroom had just been fully renovated with brand new ceramic tiles, but within a few weeks, moisture stains were already appearing on the ceiling.

We recommended and installed a Panasonic WhisperCeiling® 110 CFM fan, known for its quiet operation and efficiency. Thanks to an installation in the attic, with an insulated duct connected to a protected outdoor vent, we were able to:

• Extract humidity in under 10 minutes after a shower.

• Maintain optimal humidity levels below 50%.

• Prevent any mold from forming.

The client noticed an immediate improvement in comfort and air quality.

The concrete benefits of professional ventilation

Here’s what you gain when you choose a professional HVAC ventilation installation with AirGreen:

• Protection of your renovation investment.

• Increased everyday comfort (fresh air, fog-free mirrors).

• Improved indoor air quality (fewer allergens and spores).

• Reduction of persistent odors.

• Compliance with the Quebec Building Code.

• Added property value in case of resale.

Minimum standards... and why you should go further

According to the Quebec Building Code, a bathroom must be equipped with a mechanical ventilation system capable of renewing air at a rate of 50 CFM (cubic feet per minute). However, our recommendations often exceed these minimum standards to ensure true comfort and sanitation, especially for bathrooms shared by multiple people or with no windows.
