Tonnage â¦ the unit of measure used in air conditioning to describe the cooling capacity of a system. One ton of cooling is based onthe amount of heat needed to melt one ton (2000 lbs.) of ice in a 24hour period. As a rule of thumb, 400 square feet can be cooled per 12,000 BTU/hr (12,000 BTU/hr equals one ton of air conditioning). However, other factors which will also affect the total heat load. â¢ Simply put, a one-ton air conditioner can remove 12,000 BTU from a space per hour.
