I need to find info on an air conditioner unit. I have a Heil 10 - Model# NAC042AKA4, Serial #L022109038 with a Trane A-Coil (don't have any #'s on coil). I need to find out what the tonage is, year made, and how much it is worth. I got it about 4-5 years ago, and the lady I got it from said it was 4 years old then. I never used it because it's too big for my furnace - need to sell, but I do not know the tonage or age. It works great.

Thanks,

KT

According to the model # it is a 2 ton unit and the serial number indicates it was made in 2002 and it is a 10 SEER unit.

Hi random, that's a 42 in the model, not a 24. I misread it at first too. I believe that is a 3 1/2 ton unit.

@mygirlsdad77 same with me I mistaked it for a 24 instead of a 42 lol

Selling house. Buyer wants to know size of A/C unit. How do I determine?
