In this manner, how do I tell what size my AC unit is?

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 can you tell how old your AC unit is? Go to the outside cabinet of the air conditioning system. You'll find a metal nameplate attached to it containing the system's technical specs.

Beside this, how can I tell what tonnage my Goodman air conditioner is?

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.

How can I tell how many BTU my air conditioner is?

The digits you need The 3 digits in the model number tell you the nominal capacity in thousands of BTU/hr. Since each 12,000 BTU/hr is equivalent to 1 ton of air conditioner capacity, it's easy to figure out how many tons of nominal capacity your AC has.

How do I determine the tonnage of my AC unit?

Area Method : To calculate, multiply the length and breadth of the room (in feet), take square-root of the answer and divide by 10. The resulting number will give the desired tonnage. Volume Method : Alternatively, multiply the length, breadth and height of a room (in feet). Divide the answer by 1000.
