Pitched Roof Curb and Other Issues
Hello everyone,
I have a 2 story house, approximately 2,200 square feet. I have two units installed; one upstairs, one downstairs.
I am replacing the downstairs one with a slightly larger unit. Current unit is a SMALL 28x28 cube. I'm putting a 36x36 unit up there.
I currently have what looks to be a sheet metal curb platform, but it will no longer work due to size and rust. Where the heck do you buy A/C platforms, curbs, etc? I don't want to get the angle iron adjustable stand because I don't want to drill holes into my 3 year old roof.
Also, the old AC has a side draft opening of 15x15...and the new one is 18x18. I am having trouble finding a duct reducer or transition. I would even attempt to make my own if I could find an 18x18 duct that I could cut and rivet. It's strange how hard it is to find some of this stuff.

Duct work is typically made on demand. Look for a duct supply "tin knocker" in your areas. They can make any size duct needed.
A platform and a curb are two different things. Curbs are built in place to a certain size.
