Commercial heating and air conditioning systems serve the same purpose as residential systems by maintaining a comfortable environment. However, the differences between them are significant beyond just providing comfort.
Commercial HVAC systems are typically larger, more powerful, and must address specific business-related issues for success. Therefore, you need a commercial HVAC contractor in Franklin Township that understands the unique requirements of your property, rather than merely applying residential HVAC knowledge.
A common term you might have encountered is “tonnage,” as in “What tonnage does a business need for effective climate control?” Contrary to what it sounds like, tonnage does not refer to the weight of an HVAC system but to its cooling and heating capacity. Determining the appropriate tonnage for a commercial or industrial facility is a crucial part of the work we do for commercial business owners in our community.
Understanding Tonnage
Most commercial facilities use a rooftop packaged HVAC unit for heating and cooling. These units are heat pump systems that circulate refrigerant to transfer heat: in heating mode, they move heat from outside to inside, and in cooling mode, the process reverses.
The power of these units is measured in BTUs (British Thermal Units), where one BTU is the amount of heat needed to raise the temperature of one pound of water by 1°F. While a typical window air conditioner can move about 5,000 BTUs of heat per hour, commercial systems are much more powerful, hence the use of the larger measurement of tons to describe their capacity. One ton of heating or cooling power equals 12,000 BTUs. The term “ton” originates from the amount of heat energy needed to melt a ton of ice in an hour.
Determining Your Facility’s Tonnage Needs
The range of tonnage for commercial air conditioners and heaters is vast. While residential systems range from 1.5 to 5 tons, commercial systems can be 10, 25, or 50 tons, with larger facilities often using multiple 50-ton units for adequate heating and cooling.
This highlights the importance of working with experienced commercial HVAC contractors for heating and air conditioning installation or replacement. Only a trained and experienced contractor like the ones on our team can accurately determine the right tonnage to ensure comfort, process efficiency, and equipment protection. Incorrect tonnage can lead to significant issues and high replacement costs for inadequate equipment.
Trust our technicians to collaborate with you in assessing your facility’s specific needs. They will perform a heat load calculation to understand how your facility traps and generates heat, using this information to determine the proper tonnage.
