An advanced HVAC maintenance strategy that transforms system longevity in Montréal, Laval, and beyond
At AirGreen, we don’t just install high-performance air exchangers in residential and commercial buildings across Montréal, Laval, Longueuil, the North Shore, and the South Shore. We’re committed to maximizing the performance and lifespan of every unit. With years of hands-on experience, we’ve developed an exclusive maintenance and proactive management method that allows us to double the lifespan of air exchangers, while maintaining a high standard of indoor air quality. Here are the proven practices we implement every day with our clients.
The problem: why do so many air exchangers break down prematurely?
In over 70% of the service calls we receive for broken or underperforming air exchangers, the root cause is lack of maintenance or improper use. Filters never cleaned, clogged exchangers, CO₂ detection turned off, poorly installed ducts — small oversights that, over time, lead to costly breakdowns.
The AirGreen approach: prevention, precision, and strict protocols
1. Filter cleaning every 3 months – not just in the spring
At AirGreen, we advise all our clients to clean or replace their air exchanger filters at least four times a year. We even send automatic reminders to clients enrolled in our maintenance program.
2. Annual calibration of smart sensors
A poorly calibrated CO₂ or humidity sensor can throw off the entire ventilation logic. Our trained HVAC technicians perform a full electronic check once a year to ensure each sensor complies with manufacturer standards.
3. Full internal cleaning every 2 to 3 years
We perform complete internal cleanings of air exchangers, including fans, exhaust ducts, heat recovery cores, and defrosting systems. This service is essential to preserve energy efficiency and prevent mold buildup.
Case study: extending the life of a Lifebreath unit in Longueuil
In 2017, we installed a Lifebreath RNC 205 air exchanger in a single-family home in Longueuil. At the time, the homeowner committed to following our full maintenance program. Today, after 7 years of continuous operation, the unit is still running at full capacity, with no efficiency loss and no major part replacements.
The keys to success?
-
Thorough cleaning every quarter
-
Annual preventive maintenance by AirGreen
-
Continuous monitoring via built-in sensors synced with the Lifebreath mobile app
Mistakes to avoid if you want to extend your air exchanger’s lifespan
Skipping regular maintenance
A dirty filter increases airflow resistance, puts strain on the motor, and reduces unit efficiency. Result: avoidable premature failure.
Installing without a proper ventilation plan
We still see too many improvised installations, with no airflow diagram or airflow calculations. At AirGreen, every project includes detailed airflow analysis.
Buying a model not certified for Quebec’s climate
Some low-cost exchangers lack automatic defrost features, causing blockages in winter. All models we install are tested for Montréal’s climate and ENERGY STAR® certified.

The role of client training: a crucial but often neglected aspect
After every installation, we train clients on optimal system use, basic maintenance, and how to respond to alerts. A 20-minute session that can prevent many issues.
