The Model / Serial data label was almost always on the outside of the control box cover on the older comfortmakers. (see picture) I've seen a few high efficiency models where the label is down near the lineset connection on the cabinet. The labels typically peel off or become unreadable after a few years of weathering - If you find that you have a label with no printing on it you can sometimes rub a little dry dirt on it to get the lettering to show up (only slightly and still really hard to read). - Also, most cell phone cameras have better contrast than your eye - I can sometimes take a picture of an unreadable label and I can read it in the photo. - Unfortunately, If the label is missing no amount of dirt will bring it back....

You might have better luck with the compressor model number and serial number - Those are usually on stamped metal plates that don't wear off - The manufacturer (or a distributor) might be able to cross reference those numbers and determine the unit info.

Again I cannot see the plate on the compressor how can I where is it on the compressor

Comfortmaker uses Copeland compressors so the tag is probably on the side of the casing near the bottom - Probably hard to see unless you take the top off and get down between the compressor and the coil
