Hope this helps

Great site…but it would be a lot better if they included a SEER rating with the age.

Thanks, great link, however that puts the Coleman outside condenser at 2005, I expected it to be much older due to the condition. WOC5805510

That model was manufactured from 1998 to 2004.

That does not match up with the chart from the link you provided earlier listed below.

I didn’t provide that chart. My info comes from Preston’s Guide (1960-2005 Ed.)

I tried the site to find a westinghouse furnace FG100202785 and didn’t have any luck. I know it is fairly new. Did they change the serial number sequence?
