Q: What does BTU and Tonnage Mean?

BTU (British Thermal Unit) measures the amount of heating or cooling energy a commercial rooftop packaged unit can produce per hour, while tonnage measures the unit's nominal cooling capacity. One ton of cooling equals 12,000 BTU/h, meaning a 10-ton commercial rooftop unit provides approximately 120,000 BTU/h of cooling capacity. Both measurements help contractors and customers determine the appropriate HVAC system size and output for a building's heating and cooling requirements.
