Commercial HVAC systems are best for large buildings, regardless of their nature. These systems can cool or heat air, distribute the load among various mechanical systems and control the environment using simple thermostats. All this makes them economical and reliable for busy, buildings with heavy human traffic. Commercial HVAC is best for proving heating, ventilation, and cooling to individual floors of large buildings and complex structures. These systems are actively employed in industrial, commercial, and institutional buildings to adjust the variable outdoor air conditions with the required indoor ones as per the occupant’s requirement.

To figure out how big an air conditioner you'll need for a room, multiply the room's length by its width. Then multiply that by 25 BTU to achieve a sufficient amount of cooling for the room in all weather conditions.AC size is determined in terms of weight. i.e., tons. The larger the area, the heavier will be the AC’s compressor. For example, a 600-1000 square feet area needs a 1.5-tons air conditioner, 100-1500 square feet, a 2-tons AC, 1500-2000 square feet, a 3-tons AC, and 2000-2500 square feet, a 4-tons AC respectively.
