How do I find out the tonnage of my AC unit?
Your AC tonnage can easily be found by going outside and looking on the AC unit itself. When outside, you should see a data plaque mounted to the side of the condensing unit. Look for the model number, which is a combination of numerals and letters. Within this combination, you should find an even, two digit number.
How do I read my air handler model number?
Look at the model number (Located on the data plate stamped on the actual side of the compressor) on the compressor and there should be a number divisible by 12. It should start at 18 and not be more than 60 for residential AC units. 18 to equal 1.5 tons and 60 to equal 5 tons of cooling.
