🤔 What is BTU and TON?

BTU (British Thermal Unit) measures how much heat an air conditioning or heating system can transfer in one hour. A higher BTU means a more powerful system, capable of cooling or heating larger spaces.

TON is a standard HVAC unit of measurement. One ton equals 12,000 BTU/hr, making it easier to understand cooling capacity in everyday terms.
