An AirGreen installation on the North Shore clearly demonstrating the real impact on indoor air quality
On the North Shore of Montreal, in a single-family home located in Blainville, our team at AirGreen recently completed a HVAC installation of a floor-ceiling unit at the request of a couple concerned about the air quality in their home. This project was not just a response to a thermal comfort issue but a true commitment to better indoor air quality and enhanced energy performance. Thanks to rigorous planning, careful equipment selection, and the expertise of our certified technicians, this installation delivered measurable and lasting results.
Why a floor-ceiling unit? A strategic choice for North Shore residences
Floor-ceiling units are often underestimated in residential projects, yet they offer exceptional versatility, especially in homes with low ceilings or complex architectural configurations. In the case of this residence in Blainville, several factors made this solution ideal:
-
Restricted room layout preventing a classic wall installation
-
Limited ceiling height in certain areas
-
Need for uniform air distribution across a large open area
-
Objective: improve air quality and reduce humidity presence
Our choice fell on a Daikin brand floor-ceiling unit, model FNAQ24AV1, with a capacity of 24,000 BTU, equipped with an advanced filtration system and compatible with smart thermostats. This model is also eligible for Hydro-Québec’s LogisVert program, allowing customers to receive a subsidy of up to $1,704, which strongly influenced their investment decision.
Installation process: an AirGreen expertise dedicated to precision
The intervention took place over a full day, divided into several key stages:
Preliminary technical analysis
We conducted a comprehensive home evaluation, including:
-
Air quality test to establish a baseline (CO2 level, VOC level, relative humidity)
-
Analysis of existing airflows and areas with stagnation or drafts
-
Determination of optimal installation points to ensure even distribution
Unit installation
The unit was installed in the main family room, a high-traffic area previously difficult to heat properly.
-
Ceiling mounting with anti-vibration suspension
-
Connection to pre-existing refrigerant lines
-
Integration into the centralized control system (smart thermostat)
Final checks and post-installation measurements
After commissioning, we conducted new air quality tests:
-
37% reduction in VOCs measured in the room in less than 48 hours
-
Improvement in air circulation according to flow meter readings
-
Humidity stabilization at 45 %the ideal threshold to prevent mold and discomfort
Customer testimonial: tangible satisfaction
“We noticed a significant improvement in our comfort from the very first night. The air is fresher, less humid, and our children sleep better. Thanks to the AirGreen team for their meticulous work and professionalism!”
– Marie-Claude & Thierry, Blainville
Impacts on indoor air quality: data and findings
Here are the comparative results before and after the unit installation:
| Indicator | Before installation | After installation (72h) |
|---|---|---|
| CO₂ level (ppm) | 1 120 | 670 |
| Relative humidity (%) | 62 % | 45 % |
| Volatile organic compounds | 360 µg/m³ | 225 µg/m³ |
| Average temperature (°C) | 19.5 °C | 21 °C |
| Draft points | 5 zones | 1 residual zone |
These results clearly demonstrate the effectiveness of a well-selected and properly installed floor-to-ceiling unit by professionals like AirGreen. The decrease in CO₂ and VOC concentrations shows better ventilation, while the reduction of draft zones significantly improves overall comfort.
