How Do You Determine Ac Tonnage Size

To estimate your AC tonnage needs, multiply the number of square feet you’re cooling times 25. This equals the total number of BTUs you need to adequately cool your space. Next, divide that number by 12,000 to determine the tonnage capability you need in your new air conditioning unit.

How do you check my AC is 1 ton or 1.5 ton?

Find the model number. Within this string of letters and numerals, you should find an even, two-digit number. The possibilities on residential units range from 18 to 60. Divide the number by 12 (which represents 12,000 Btu/hr, or one ton of cooling capacity) to get your AC unit’s tonnage.

How many square feet does a 2 ton AC cool?

Units that are 2 tons can cool off 901-1200 square feet spaces. Units that are 2.5 tons can cool off 1201-1500 square feet, etc. This pattern continues up to units of 5 tons that cool off 2401-3000 square feet, with every half ton increase adding about an additional 300 square feet.
