Hey savvy business owners and facility managers! When it comes to keeping your commercial space cool and comfortable, choosing the right air conditioning system is absolutely critical. Whether you’re outfitting a small office or a larger retail or industrial space, picking between a 3 ton commercial AC unit and a 5 ton commercial AC system can make all the difference in efficiency, costs, and comfort.
In this guide, I’m breaking down everything you need to know about these popular commercial AC sizes, their differences, and how to pick the right one for your specific needs. Plus, I’ll sprinkle in some insights on the Goodman 3 Ton 14.5 SEER2 R-32 bundle—an excellent option for those who want reliable performance and energy efficiency.
Understanding Commercial AC Sizes: What Does “Ton” Mean?
When we talk about a 3 ton commercial AC unit or a 5 ton commercial AC, we’re referring to the system’s cooling capacity. A "ton" in HVAC terms represents the ability to remove 12,000 BTUs (British Thermal Units) of heat per hour.
-
A 3-ton AC can remove about 36,000 BTUs per hour—ideal for smaller commercial spaces or well-insulated offices.
-
A 5-ton AC removes roughly 60,000 BTUs per hour, designed for larger spaces like warehouses, retail stores, or open-plan offices.
Picking the right tonnage is crucial—too small and your system runs nonstop struggling to cool your space; too large and you waste energy through inefficient cycling.
The 3 Ton Commercial AC Unit: Perfect for Small to Medium Spaces
If your commercial property is in the range of 1,500 to 2,500 square feet, a 3 ton commercial AC unit is often the sweet spot. These systems provide sufficient cooling without overworking, keeping your energy bills in check.
For example, Goodman’s 3 Ton 14.5 SEER2 R-32 bundle is a fantastic option for this category. It uses R-32 refrigerant, which is better for the environment and offers efficient cooling performance. This system is also a breeze to install and maintain, making it a favorite among HVAC pros for commercial use.

Why You Might Need a 5 Ton Commercial AC Unit
Larger commercial spaces—think 3,000 square feet and above—often require a 5 ton commercial AC unit to keep the air comfortable. This size is popular in warehouses, restaurants, and large retail stores where heat loads are higher due to space size, equipment, and occupancy.
While a 5-ton system consumes more energy than a smaller unit, modern units with good SEER ratings (Seasonal Energy Efficiency Ratio) can keep operating costs manageable. Brands like Daikin and Lennox offer commercial units with solid efficiency ratings designed specifically for these applications.

Factors That Influence Your Choice Beyond Just Size
Remember, tonnage alone isn’t the full story. Other factors can influence what system works best for your commercial building:
-
Building Insulation: Better insulation means you might get away with a smaller unit.
-
Occupancy Levels: More people means more heat, requiring extra cooling capacity.
-
Equipment and Lighting: High-heat generating equipment can increase cooling needs.
-
Local Climate: Hotter climates demand more robust cooling.
