To calculate tonnage, divide the BTUs by 12,000, which is the weight of one refrigeration ton. For example, a unit with 18,000 BTUs has a tonnage of 1.5. The Goodman Manufacturing Company website provides product specifications, including model numbers, for all current air conditioning units and some older models.

In this way, What is ton in AC? A ton is the cooling capacity of an air conditioning system. One ton is equal to the amount of heat required (288,000 Btu) to melt one ton of ice in a 24-hour period. A one-ton air conditioner is rated at 12,000 Btu per hour (288,000/24). A two-ton unit would be rated at 24,000 Btu per hour.

## How is tonnage calculated?

Tonnage, in shipping, the total number of tons registered or carried or the total carrying capacity. Gross tonnage is calculated from the formula GT = K1V, where V is the volume of a ship’s enclosed spaces in cubic metres and K1 is a constant calculated by K1 = 0.2 + 0.02 log10 V.

## What size air conditioner do I need for a 2000 square foot home?

If your home is 2000 square feet, you can calculate your HVAC needs the same as you would for a 1600 square foot home. Assuming one ton of cooling capacity can cool 400 square feet of your home, you’ll need about 5.0 tons of air conditioning capacity. Multiply this by 12,000 BTUs, and you’ll get 60,000 BTUs.

## How long should my AC run?
