🤔 What is BTU and TON in HVAC?

BTU (British Thermal Unit) measures how much heat an air conditioner or heat pump can move in one hour. A higher BTU rating means a more powerful system for larger spaces.

TON is the HVAC unit of measurement that expresses cooling capacity in terms of BTU/hr. One ton equals 12,000 BTU/hr.
