How to Read the Tonnage on Your AC Unit...
One of the questions that many folks asked on yesterday's post, was how does one know the tonnage of their air conditioning system. On the system's model number there will be a number: 18, 24, 30, 36, 42, 48, 60. Take this number and divide by 12. This will give the tonnage. i.e. 1.5, 2, 2.5, 3, 3.5, 4, 5.
The only variation in this numbering scheme will be the newer Puron units. The manufacturers decided to make the evenly divisible numbers one more or one less. i.e. a 2 ton unit may have a model number that reads XXXX23 or XXXX25. Engineers, gotta luv 'em...
