Tons is a shorthand phrase that refers to the total cooling capacity of the unit in BTU's. A 3-, 4-, or 5-ton unit doesn't refer to the weight of the equipment, but instead to the amount of heat the air conditioner can remove from the home in one hour.A 3-ton air conditioner moves 36,000 BTUs of heat per hour — enough to cool a home of up to 1,800 square feet in the southernmost states. In the Northeast and upper Midwest, these units are recommended for homes between 1,651 and 2,100 square feet in size.
