Professional, cost-effective, and sustainable solutions to control temperature in industrial spaces
Cooling a warehouse is both a technical and financial challenge for many businesses located in Montréal, Laval, Longueuil, on the North Shore or South Shore. These large spaces with high ceilings, often poorly insulated or not at all, generate intense heat in the summer, threatening not only staff comfort but also the integrity of stored goods. At AirGreen, we know that a poorly adapted commercial HVAC system can lead to major additional costs. That’s why we’re presenting here the 5 best economical solutions to cool a warehouse efficiently, based on our hands-on expertise and successful installations across Greater Montréal.
Why choose an economical HVAC solution for your warehouse?
Investing in a high-performance yet affordable industrial cooling system means maximizing comfort and productivity while controlling your energy expenses. Many of our clients—whether wholesalers in Laval, logistics firms in Longueuil, or manufacturers on the South Shore—are looking to optimize their energy consumption without compromising performance. Thanks to our extensive experience in commercial HVAC installations, we’ve identified the most cost-effective approaches on the market.
1. High-capacity wall-mounted air conditioners for targeted zones
An affordable and effective option is to install high BTU wall-mounted air conditioners, such as the Gree T-Fresh 36,000 BTU model, which is perfectly suited for warehouses with specific areas that need cooling.
Why it’s a good idea:
-
Localized cooling for critical zones (packing, receiving, integrated offices).
-
Lower installation cost than a full central system.
-
Ability to modulate based on how the space is used.
Real-world example:
In Boisbriand, we installed two Gree T-Fresh 36,000 BTU units in an 8,000 sq. ft. logistics warehouse. The result: an immediate 7°C drop in the temperature of the busiest work zones, all while keeping energy costs under control.
2. Variable Refrigerant Flow (VRF) HVAC systems
VRF (Variable Refrigerant Flow) systems offer a modular and energy-efficient solution for large industrial spaces.
Key benefits:
-
Ability to control the temperature of multiple zones independently.
-
Up to 40% energy savings compared to traditional systems.
-
Quiet operation, ideal for warehouses with on-site staff.
Brands we install:
Fujitsu Airstage VRF, Mitsubishi City Multi, Daikin VRV – all tested and proven in our projects across Montréal.
3. Natural ventilation assisted by mechanical extraction
For well-ventilated or newly built warehouses, natural ventilation supported by mechanical extraction fans remains one of the most cost-effective strategies.
Details:
-
Installation of high-capacity rooftop exhaust fans.
-
Passive cooling of indoor air through continuous heat evacuation.
Benefits:
-
Very low energy consumption.
-
Low installation cost.
-
Minimal maintenance.
Real example:
In Varennes, we equipped a 12,000 sq. ft. agricultural warehouse with a combined natural ventilation + mechanical extraction system using Zephyr Commercial 5500 CFM fans. The result: improved thermal comfort without relying on active air conditioning.
4. Evaporative cooling systems (adiabatic coolers)
An eco-friendly and budget-conscious alternative, evaporative cooling is based on a simple principle: outside air is drawn through a moistened filter, cooled by evaporation, then blown indoors.
Advantages:
-
Extremely low operating costs.
-
Perfect for warehouses with frequently open doors.
-
No refrigerant gases involved.
Important notes:
-
Works best in low-humidity environments.
-
Doesn’t allow for precise temperature control.
AirGreen installation:
In Sainte-Julie, for a mechanical warehouse, we installed 4 Portacool Jetstream 270 units, which brought the ambient temperature down by 10°C in the open work zones.
5. High-efficiency commercial heat pumps
Modern commercial heat pumps, like the Bosch BOVA or Gree Versati, offer an excellent balance between performance, cost, and return on investment—especially when they are eligible for government grants.
Highlights:
-
Dual function: heating in winter, cooling in summer.
-
High performance ratings (SEER, HSPF).
-
Compatible with government subsidies (e.g., LogisVert, Transition Énergétique Québec).
Successful project:
For a manufacturing client in Saint-Eustache, we installed a Bosch BOVA 60,000 BTU system with ducted distribution. The return on investment was estimated at just 3 years thanks to a 35% reduction in annual energy costs.
Practical tips for choosing the right budget-friendly HVAC solution
1. Assess how frequently the warehouse is occupied
Some warehouses don’t require constant cooling. An intermittent system, such as wall-mounted units with timers, may be sufficient.
2. Prioritize zoning
Cooling an entire warehouse is often unnecessary. It’s better to identify critical zones (production, handling, storage of fragile goods).
3. Take advantage of available grants
We help our clients access applicable grants, which can cut system costs by up to 50%.
4. Don’t overlook maintenance
A poorly maintained system loses efficiency. We offer customized commercial HVAC maintenance packages.
