2 1/2 ton unit the 30 in model number means 30000 btus 2 tons + 1/2 ton = 2 1/2 tons of air conditioning
Looks like 3 tons from the model #
2.5 ton at least a good guess due to the 30 in the middle of the model number. Which would stand for 30,000 btu's or 2.5 tons. How large of an area does this unit cool?
2.5 tons. 1 ton =12,000 btu so 30,000 btu=2.5 tons. The 30 in the model # denotes btu of the unit in 1000`s.
It`s found in the condensing unit model #.
Find the specification plate on the outside unit or ask for specs on the model number here or the Mfgs website or look on the AC compressor inside the outside unit for it's model number and call a local parts dealer for the specs for that compressor. >>>>> A usually reliable rule of thumb to find this yourself is to find the unit Model # on the outdoor unit`s tag and there will be 2 digits in the model# indicating capacity. AC units are sized in tons and a ton is 12,000 btu. So those 2 digits will normally indicate capacity in 1000`s of btus. 24=2tons, 30=2.5 tons, 36= 3 tons, 42=3.5 tons, 48=4tons, 54=4.5 tons and 60=5 tons.
Look at the tag on the outdoor unit. Somewhere in the model # will be a 2 digit number that is divisible by 6. Get that #, divide it by 12 and you have your answer. 24= 2 tons, 30= 2.5 tons etc.
