A quiet installation, a major impact: how the air exchanger became the silent hero of air quality
At AirGreen, we know that installing an air exchanger doesn't often make the headlines. However, some of the interventions we've carried out in Montreal, Laval, Longueuil, the North Shore, and the South Shore have made a real difference for several families and businesses, preventing major health, material, or financial catastrophes. In this article, we’ll share five true, authentic, and remarkable stories where an air exchanger literally saved the day.
A House in Laval Saved from Invisible Mold
It was in a peaceful residential area in Laval that a young couple reached out to us, concerned about a persistent odor in their renovated basement. At first glance, there was no visible trace of mold. However, using an air quality sensor, we detected an excessive humidity level and mold spores suspended in the air. The existing ventilation system, rudimentary at best, wasn’t designed to handle a well-insulated and sealed home.
We installed a Venmar EVO5 700 HRV air exchanger, a high-performance and discreet model with heat recovery. Within just a few days, the humidity dropped, odors disappeared, and sensors reported a significant improvement in air quality. The couple avoided expensive decontamination work, and most importantly, health risks for their asthmatic child.
A Daycare in Longueuil Narrowly Avoids Administrative Closure
At a small daycare in Longueuil, we received an urgent call. Following a Public Health inspection, the CO₂ levels in the common rooms exceeded acceptable limits. The existing ventilation system, outdated and insufficient, wasn’t providing the necessary air exchange for such a frequently used space.
We responded within 24 hours, evaluated the site, and recommended a solution: the installation of two Lifebreath 195ECM air exchangers, durable and energy-efficient. With their high airflow and quiet operation, the air was continuously filtered and renewed without disturbing the children.
The result: the daycare avoided closure, complied with ventilation regulations, and even saw a noticeable reduction in illness rates among the children during the winter months.
A Condo in Montreal Saved from Destructive Condensation
A condo owner in Rosemont, Montreal reached out to us after noticing excessive condensation on their windows, to the point where water was dripping each morning. Upon investigating, we discovered that the heating system was efficient, but the unit had no adequate ventilation system.
The solution? Installing a Fantech VHR 150 air exchanger, combined with an intelligent humidity controller. By efficiently redistributing dry, warm air, we eliminated the destructive condensation that was threatening the windows, woodwork, walls, and structural integrity of the building.
The owner later told us: “Without your intervention, I would have had to replace the windows for nothing. The air exchanger changed everything.”
An Intergenerational Home on the South Shore Avoids Poisoning
In an intergenerational home in Brossard, a family had been experiencing recurring symptoms: headaches, fatigue, nausea… suspecting an air quality issue, they called us.
Upon inspection, we discovered that the gas furnace combustion system was emitting low doses of carbon monoxide — too low to trigger an alarm, but enough to impact health. The problem was poor ventilation and lack of fresh air intake.
We urgently installed an Aldes InspirAIR Side air exchanger, paired with an intelligent CO detector. Not only was the air renewed continuously, but contaminants were filtered before being redistributed throughout the rooms.
Since then, the entire family has been breathing better. One of the members even saw their diagnosis of “reactive asthma” completely disappear. Without intervention, the risk of carbon monoxide poisoning could have been fatal.
An Industrial Workshop on the North Shore Avoids a Fire
In a small food processing workshop in Boisbriand, the owner called us to improve the ventilation. He was concerned about the excessive heat accumulating near the motors and the ceiling, where the air had become stagnant.
Our diagnosis revealed a risk of greasy vapor accumulation combined with excessive heat, which could have sparked a fire if exposed to a spark.
We proceeded to install three Fantech SHR industrial air exchangers, each equipped with grease filters and an automatic control system based on ambient temperature. Not only did odors vanish, but the temperature remained stable even during peak production times. A fire department inspection confirmed that the fire risk was eliminated.
Why Trust AirGreen for Your Air Exchangers?
Each of these stories proves one thing: a properly selected and installed air exchanger can prevent invisible but serious disasters. At AirGreen, we don’t just sell equipment, we offer customized solutions that take your building, lifestyle, and real challenges into account.
We serve Montreal, Laval, Longueuil, the North Shore, and the South Shore, with a team of experienced technicians, certified ENERGY STAR products, and in-depth knowledge of available government grants, such as the LogisVert or Rénoclimat programs.
How to Choose the Right Air Exchanger?
Here are some criteria that we assess during each installation:
-
Size and configuration of the building
-
Presence of moisture or combustion sources
-
Number of occupants
-
Daily activities (cooking, workshops, daycare, etc.)
-
Insulation level
By combining these factors, we recommend either a Heat Recovery Ventilator (HRV) or an Energy Recovery Ventilator (ERV), depending on your needs, always with installation compliant with CSA-F326 standards.
Grants Available to Optimize Your Budget
Some of the installations mentioned above allowed our clients to benefit from subsidies of up to $1,500, thanks to programs like:
-
LogisVert from Hydro-Québec
-
Rénoclimat
-
Chauffez Vert
We guide you through every step of the administrative process to maximize your benefits.
