A Custom HVAC System to Preserve the Integrity of a Wine-Lover’s Jewel in Saint-Lambert
In the South Shore, in the peaceful city of Saint-Lambert, a client passionate about fine wines contacted us for a delicate mission: to preserve the integrity of his high-end wine cellar with a custom HVAC installation. At AirGreen, we took on this challenge with expertise, precision, and creativity, once again demonstrating our unique know-how in the field of specialized ventilation. Here’s the story of this demanding intervention, where technical precision and strict conservation standards came together to protect an invaluable wine heritage.
A Complex Issue in the Heart of the South Shore: Humidity, Temperature, and Air Circulation
The client, an experienced collector, had a 60 m² wine cellar located in the basement of his Saint-Lambert home, on the South Shore of Montreal. Despite a passable temperature control provided by a wall-mounted air conditioning system, some alarming signs began to appear: dried-out corks, condensation on the bottles, and mold developing on the noble wood shelving.
These issues all pointed to a fundamental problem: the absence of proper ventilation, combined with poor humidity regulation. In fact, a wine cellar requires very specific conditions to ensure proper wine aging:
-
A stable temperature between 12°C and 14°C
-
A constant humidity level of 60% to 70%
-
Gentle air circulation, avoiding stagnant air
-
Complete thermal insulation
Site Analysis and Custom HVAC System Design
From our very first visit, our expert team carried out a comprehensive analysis of the space: ceiling height, materials used in the cellar, natural airflow, ambient humidity levels, and insulation. We also took into account the fragility of the construction materials (wood, natural stone, wrought metal) and the value of the wine collection, estimated at over $300,000.
Following this assessment, we developed a precise action plan based on the following elements:
-
Installation of a ventilation system with a heat recovery ventilator (HRV)
-
Integration of a central dehumidifier Honeywell DR120, connected to the ventilation system
-
Addition of smart temperature and humidity sensors, with remote control via mobile app
-
Creation of concealed ductwork to preserve the cellar’s high-end aesthetic
Equipment Selection: Efficiency, Discretion, and Durability
For this highly specialized installation, we selected a Venmar EVO5 700 HRV heat recovery ventilator, ideally suited for small residential spaces with strict demands. This model features:
-
An airflow rate of 110 CFM, perfectly adapted to the cellar
-
Heat recovery technology optimizing energy savings
-
Ultra-quiet operation (under 1 sone)
-
HEPA filters capturing 99% of airborne particles
All of this was paired with a central dehumidifier Honeywell DR120, known for its 120-pint/day capacity, ensuring a constant humidity level without affecting the temperature.
Technical Challenges and On-Site Solutions
One of the main challenges was to install the ventilation ducts without compromising the aesthetic of the space or the airtightness of the cellar. To address this, we:
-
Used insulated flexible acoustic ducts, hidden inside custom cornices
-
Reinforced insulation with high-density rigid polyurethane foam
-
Installed brushed aluminum air vents, stylish and discreet, blending with the décor
-
Conducted smoke tests to verify airtightness before commissioning the system
Results After Installation
Since the system was activated, the client has observed perfect preservation conditions:
-
Stable temperature at 13.2 °C
-
Humidity level maintained between 65% and 67%
-
No mold formation
-
No condensation on the bottles
Air now flows smoothly, with no noticeable noise or direct drafts. Thanks to the connected module, the client can adjust settings remotely and receives alerts in case of anomalies.
Client Testimonial
“I reached out to AirGreen after a series of bad experiences with other contractors. Their approach was both technical and human. They understood that this cellar was more than just a space—it was a passion, an investment, a legacy. Today, I sleep peacefully, and so do my wines.” – Mr. D., Saint-Lambert
