Does anyone here know a good industrial supply website that has HVAC listings where I can look up products by manufacturer? I am trying to look up a lot of items, so I need a good catalog search.

McMaster-Carr is no good because they don't give the manufacturer names and numbers. Grainger has too limited a selection.

Johnstone would be great, but their search stinks. It's something like a Johnstone that I am looking for.

Any ideas?
