The 48 in the serial number denotes the tonnage. Divide that number by 12 to get the tonnage of 4.
you don't, it's in the model number. the first 2 numbers are the tonnage
What is the serial number? Usually it is in this number.
2006 hence,06 at the beginning.
Possibly that it was built in august of 09
It is a 2 1/2 ton packaged heat pump. You can tell the year and month made by the serial number. The first two digits are the year and the next two are the month it was manufactured. All goodman and Amana units are this way.
the date is on the data plate just about the service valves on the outside condenser. the serial number is how you can read the manufacture date. for example, serial number 9805100565, is read as manufactured in may 1998. this is the for all goodman and amana air conditioning units.
95 is the year it was built and 09 is the month it was built.
Serial#
2.5 tons, n2a330akc200 the 30 in the serial means 2.5 tons
The AHU unit does not have a tonnage rating, since all AHU`s can accept a number of different tonnage evaporator coils. Your best bet would be to post the condensing unit model and serial#`s.
have a day and night air conditioner with a model number 585HJ042060 and serial number of 1985C87813 would like to confirm that indeed this model exist.
