2.5 tons. Whenever you see multiple digits digits together in a model #, any brand, the last 2 digits in the FIRST series of numbers is the btu output. So in this case you take the 30 out of nxh530gka100 and you have 30.

! ton of cooling is equal to 12,000 btus

so 30 is 30,000 btus divided by 12,000 equals 2.5
