Hey all -
I've been lurking for a bit in preparation for my AC system to finally die. Looks like it passed away Tuesday night.
The system was a Dunham Bush VCR36 Series E11 - it doesn't seem that DB makes residential units anymore - just commercial.
Can anyone tell me the SEER rating of that model?
As best as we can tell - it was installed in 1970.
Looking to replace it with something that is very effecient and quiet. The air handler is of the same vintage - it's up in the attic - space pack design with HV air tubes.
We are in the NW Chicago Suburban area.
