How do you size an HVAC system for a commercial?

Sizing an HVAC system for a commercial space requires a thorough understanding of the building’s size, layout, and usage. The first step is to calculate the building’s cooling load, which is determined by factors such as the number of occupants, the amount of insulation, the type of windows, and the climate. Once the cooling load is calculated, the next step is to select the appropriate HVAC system size. This is done by comparing the cooling load to the system’s capacity, which is measured in tons. The system should be sized to meet the cooling load, but not exceed it. Finally, the system should be installed and tested to ensure it is operating correctly and efficiently.
