An urgent intervention to ensure air quality and protect patients’ health
The air we breathe in a medical facility is far from a minor detail. When it comes to a dental clinic located on the South Shore, indoor air quality becomes a critical issue — both for patient safety and staff performance. Recently, at AirGreen, we were contacted urgently by a well-established clinic in the Longueuil area. The facility was facing growing complaints related to poor ventilation, causing discomfort, frequent headaches among staff, and excessive humidity threatening the medical equipment.
Faced with this critical situation, we deployed our expertise in commercial HVAC to completely transform the clinic’s indoor environment with a custom, high-end, energy-efficient ventilation solution.
Alarming symptoms: signs of an inadequate ventilation system
From our first on-site assessment, several issues were immediately apparent:
-
Humidity buildup in treatment rooms, increasing the risk of mold.
-
High CO₂ levels in waiting areas, causing fatigue and discomfort.
-
Poor air circulation despite an apparently functional system.
-
No HEPA filtration to capture fine particles and airborne contaminants.
These symptoms pointed to a serious failure in the ventilation system, in a sector where air quality is non-negotiable. For a dental clinic, this can compromise both patient health and compliance with health regulations.
AirGreen’s diagnosis: full system assessment before intervention
Our team performed a complete diagnostic of the existing HVAC system, including:
-
Airflow testing in each treatment room.
-
Measurement of relative humidity and temperature levels.
-
Analysis of ductwork and the existing air exchanger.
-
Inspection of diffusers and filters.
The conclusion was clear: the system in place, outdated and undersized, could no longer meet the demands of a modern medical facility.
Solution installed: a central ventilation system with heat recovery
We proposed — and swiftly installed — a Lennox central ventilation unit with a heat recovery ventilator (HRV), combined with medical-grade HEPA filtration. This system offered several key advantages:
-
Energy recovery via the HRV, cutting heating costs in winter.
-
High-performance filtration of pollutants, bacteria, and dental dust.
-
Balanced ventilation for each zone: waiting rooms, offices, treatment areas.
-
Smart automation with built-in CO₂ sensors.
Thanks to our experience in ventilation for healthcare settings, the installation was completed within three business days, without disrupting the clinic’s operations. We worked after hours and over the weekend to deliver a seamless service with zero downtime.
Immediate results: satisfied staff and restored safety
Just days after commissioning, the feedback was unanimous:
-
Staff reported a significant drop in end-of-day fatigue.
-
Patients noticed a fresh and clean air atmosphere.
-
Sensitive dental instruments now benefit from an optimal humidity level, extending their service life.
This project enabled the clinic to comply with the standards of the Quebec Order of Dentists in terms of ventilation, while also boosting its reputation among patients.
Why medical clinics must invest in high-performance ventilation
In healthcare settings, ventilation should never be considered a secondary concern. It plays a key role in:
-
Preventing airborne infections.
-
Protecting healthcare workers from aerosol exposure.
-
Energy savings, when equipped with heat recovery.
-
Sanitation, by ensuring constant air renewal.
On the South Shore, many clinics are located in older buildings that weren’t designed with proper ventilation for medical use. With an expert like AirGreen, that gap can be corrected quickly with tailored professional HVAC solutions.
The AirGreen difference: speed, precision, and certified expertise
We stand out thanks to:
-
Proven experience in medical ventilation, with successful projects across Montréal, Laval, Longueuil, South Shore and North Shore.
-
Our ability to act quickly in emergency situations — a decisive factor in this clinic’s case.
-
Exclusive use of high-quality equipment like Lennox, Zephyr, and Venmar.
-
Installations that comply with CSA and ASHRAE standards, adapted to sensitive environments.
At AirGreen, we don’t offer one-size-fits-all solutions. Each project receives a personalized assessment, full technical support, and a turnkey installation by our certified technicians.
Practical advice for healthcare facilities in 2025
Based on our expertise, here are some key recommendations:
-
Have your ventilation system inspected at least once a year, especially in medical settings.
-
Ensure that filters in use meet medical-grade standards (HEPA, MERV-13 or higher).
-
Maintain full air renewal every 10 to 15 minutes in treatment zones.
-
Choose smart sensors to automatically adjust ventilation based on occupancy levels.
These best practices ensure a safe, healthy environment that complies with today’s strict sanitary requirements.
