How do you tell what Ton my Carrier 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.

In this way, how can I tell what year my carrier unit is?

More recently Carrier has simplified things using the first four digits of the serial number to signify the age, where the first two digits indicate the week and the third and fourth digits indicate the year of manufacture (similar to Bryant).

Subsequently, question is, how many square feet will a 3 ton AC cool? METHOD 2: Go by square feet + climate

HVAC System Sizing

3.5 tons 2101-2300 sf 2001-2250 sf
4 tons 2301-2700 sf 2251-2700 sf

In this manner, how do you determine the tonnage of a Goodman air conditioner?

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.
