Angry Please help with this model: G-U 400100 - 16M

G-U 400100 - 16M

I think it has a date of 1982 on it. I need to know how many TON it is. It is AC/HEAT unit combined.

I think it is from comfortmaker. I cannot locate any info on this unit.

Is there anyone I can call or does anyone have any info on this?

Efficiency? Ton? Manual?

Welcome to the forums.

I can't answer your questions directly as I'm not familiar with your unit and can not find it listed in the model lineups.

Your furnace is over 30 years old. If you haven't done so should have the heat exchanger cleaned and checked for rust thru. It's very common for older heat exchangers to rust thru and allow burning gases into the airstream that delivers heated air to the house.

In case you don't get any replies maybe the following link will help.
The company has changed names during it's operation.

Comfortmaker was acquired by Inter City Products I believe in the late '80s or early '90s. Inter City Products was acquired by Carrier Corporation I think in the late '90s and the name was changed to International Comfort Products. If your unit was manufactured in 1982, that was before any of these acquisitions. It's not likely you'll find much information on your unit, but I believe your best bet is to contact ICP USA by checking the link PJ provided.
