Invisible yet essential HVAC solutions to preserve artistic integrity
Art galleries are spaces where every detail matters. Whether it’s a classical painting, a contemporary sculpture, or a multimedia installation, precise climate control is essential to the preservation of the artwork. Temperature, humidity, airflow, and filtration must be meticulously managed to prevent invisible — yet irreversible — deterioration.
At AirGreen, we understand that commercial air conditioning in an artistic space cannot be treated like a standard installation. Across Montréal, Laval, Longueuil, the North Shore and the South Shore, we design HVAC systems that meet museum-level standards, offering discreet, stable performance fully integrated into the architectural setting.
Case study: AirGreen’s intervention in an art gallery in Plateau-Mont-Royal
We were recently contacted by a contemporary art gallery in Plateau-Mont-Royal. This internationally recognized private institution was hosting a temporary exhibition of analog photographs — extremely sensitive to heat and humidity.
The existing air conditioning system could not maintain stable temperatures in the main exhibition rooms, with fluctuations of up to 4°C depending on the time of day. In addition, relative humidity often exceeded 60%, posing a risk to photographic paper and precious wooden frames.
Initial diagnosis: identified challenges
During our initial assessment, our team identified several critical issues:
-
No zoned control for different exhibition rooms
-
No humidity regulation
-
Inadequate filtration of fine particles and pollutants
-
Visible equipment disrupting the gallery’s minimalist aesthetic
We proposed a customized HVAC solution that addressed technical, aesthetic, and museum-specific requirements.
Installed solution: low-velocity central Lennox system with integrated humidity control
To ensure fine-tuned environmental regulation while respecting the visual integrity of the gallery, we installed a Lennox Elite Series central system, paired with active humidity control and a network of invisible linear diffusers.
Technical details of the installation:
-
Central unit Lennox EL296V, dual-stage, 3 tons
-
R-410A refrigerant with variable speed modulation
-
Integrated dehumidifier, calibrated to maintain 45% relative humidity
-
Connected ambient sensor with data history tracking
-
High-efficiency MERV-13 filtration for microparticles
This system not only ensures a stable temperature (±0.5°C) but also preserves the integrity of organic materials displayed in fully controlled conditions.
Execution timeline by AirGreen
Our team planned and executed the installation in close coordination with the gallery’s management and the exhibition curator:
-
Preliminary 3D thermal simulation to identify hot spots
-
Overnight installation to avoid interfering with visiting hours
-
Ducts routed through existing drop ceilings and cornices
-
Precise sensor calibration with certified adjustment
-
Delivery of a full controlled environment report for insurance and loan purposes
The entire project was completed in 8 business days, followed by 72 hours of continuous validation testing.
Results observed after installation
The benefits measured in the following weeks:
-
Consistent thermal stability, even during peak traffic
-
Humidity maintained at 45% ±2%
-
Zero complaints from artists or conservators
-
22% reduction in energy consumption compared to the previous system
-
Conditions certified for loans from national museums
Since then, the gallery has called on us for similar work in their archives and restoration studios.

Best practices for climate control in art galleries
Common mistakes to avoid
-
Neglecting humidity: it’s often more destructive than heat
-
Installing noisy or visible systems in exhibition rooms
-
Choosing non-redundant systems that could fail mid-exhibition
-
Ignoring day/night cycles and lighting impact on microclimate
What to do instead
-
Prioritize modulating HVAC systems to avoid abrupt fluctuations
-
Integrate smart multi-zone sensors
-
Schedule regular climate audits
-
Work with a local specialist installer like AirGreen
