# Age of carrier and tonage help

Compressor ser# 0407E26332 MDL 25HBA342A300

Looks to be Brand new but I am having difficulty tranlating the ac age date and tonage with the carrier chart I have.

Curt

Air handler 042 is btu rating --3.5 tons Mfg. 16th week of 2007. Comp is bristol and should be 32,200 btus aprox 3 tons. mfg 16 week of 07

April 07 3-1/2 ton = 42,000

I concur…

I’m getting January 2007 for the compressor.

Same way I got April 2007 for the air handler.

I believe the first two digits are weeks, not months.

0407 = January 2007

1607 = April 2007

Are you sure?
I’d like to get my HVAC information squared away.

William has the same thing except that I think he has a typo for the compressor since he has both of them in his answer as the “16th week of 2007.”

OK still have questions

I get the weeks and year positions. But the BTU issue is still baffling for the compressor

air handler made sense 042 = 3.5 tons

compressor 300= 3 tons?

Someone please explain how to “ton a unit”

Thanks again.
Curt

A ton unit is 12,000 BTU of cooling therefor a 24,000 btu is a 2 ton, your hypothetical 30 would be 30,000 btu ie 2 1/2 ton.

MORE baffled than ever…see my first post. What is the tonage of the compressor? I have 3 tons now 2 1/2 tons ahhhhhhhhhhhhhhhhhhhhhh

I will figure this out on my own and so far I found enough from the ebward.com site to understand it better. The above answers are appreciated but also tell me that I should have read up on this myself. Answers range from 2 1/2 tons to 3 1/2 tons I told my client 3 and 3 1/2 and I will fix that.

the 42 in the middle is for 42,000 BTUS so its 3 1/2 tons both units are 3 1/2 tons

Thanks
Curt

Curt,

You are correct…

Correct … both are 42,000 BTU’s … or 3-1/2 Tons.

Sometimes you get variable speed air handlers that can be used for different capacity systems, so always go by the condenser. Usually capacity on the nameplate also.
