Central Air Conditioner vs Multi-Split System: Understanding the Fundamental Differences
Central Air Conditioner: Uniform and Efficient Cooling
A central air conditioner is designed to cool large areas through a network of ducts distributing cool air evenly throughout your commercial space. Ideal for large commercial establishments, this system is particularly valued for its ability to maintain a constant temperature across all rooms simultaneously.
Advantages of Central Air Conditioning:
-
Even distribution of cool air.
-
Full integration possible with existing heating systems.
-
Centralized control simplifying overall temperature management.
-
Discreet aesthetics, as units are typically hidden in mechanical rooms.
However, its installation can be more complex, requiring sufficient space for ductwork, and may involve higher upfront costs.
Multi-Split System: Optimal Flexibility and Customization
Conversely, the multi-split system (wall-mounted heat pump or wall-mounted air conditioner) consists of multiple independent indoor units connected to a single outdoor unit. This type of air conditioning is especially advantageous for businesses with several rooms or zones having distinct cooling needs.
Advantages of the Multi-Split System:
-
Individual temperature control for each room or zone.
-
Simplified installation without ductwork: ideal for existing commercial spaces or renovations.
-
Significant energy savings by cooling only occupied spaces.
-
Easier maintenance due to accessible indoor units.
However, this system can be less discreet since each indoor unit remains visible on walls, potentially affecting interior aesthetics.
Essential Criteria for Choosing the Right Commercial Air Conditioning System
To make the best choice for your business in Montreal, Laval, or elsewhere, here are the essential points to consider:
1. Size and Layout of Your Commercial Space
For large open areas such as supermarkets or expansive offices, a central air conditioning system is typically the best choice. Conversely, for shops divided into smaller or partitioned spaces, the multi-split system offers precise and individualized control.
2. Energy Efficiency and Long-Term Savings
Energy efficiency is crucial for businesses mindful of their operational costs. Modern central air conditioners can deliver excellent energy performance thanks to inverter technology and high-efficiency filters. Similarly, the multi-split stands out for its ability to reduce energy consumption by specifically targeting occupied areas.
3. Cost and Ease of Installation
Multi-split systems are often more economical to install since they require minimal or no major structural work. Central air conditioners, although generally higher in initial cost, often represent a wise long-term investment, particularly in new constructions or significant renovations where duct installation is simplified.
Real Examples: Commercial Installations by AirGreen in Montreal and Surrounding Areas
Central Air Conditioner Installation – Medical Clinic in Laval
At AirGreen, we recently installed a 36,000 BTU Lennox XC20 central air conditioner in a medical clinic in Laval. The main challenge was ensuring perfectly uniform temperatures across all examination rooms while adhering to strict hygiene standards. The outcome: consistent temperature, optimal patient comfort, and significant energy efficiency improvements due to its high SEER rating of 20.
Multi-Split System Installation – Restaurant in Longueuil
In a restaurant in Longueuil, we installed a Fujitsu multi-split system consisting of four indoor units (Halcyon model, 12,000 BTU each). The unique aspect of this installation was the requirement for varied temperatures: cooler in the kitchen and moderate in the main dining area. Thanks to this solution, our client now enjoys precise control, reduced energy costs, and tailored comfort in each zone.
Mistakes to Absolutely Avoid
To optimize your choice, avoid these common mistakes:
-
Neglecting precise sizing requirements (BTU).
-
Underestimating actual energy needs.
-
Forgetting to verify available grants (such as Hydro-Québec’s LogisVert).
-
Choosing a system solely based on initial cost without considering long-term energy savings.
