Energy audit of home...tell me about them

Don't your utility companies do 'em for free? I recall the electric company did ours several years ago. I think it took about an hour (this was over a decade ago); they recommended adding insulation.

I can see why you'd be wary. If the company behind the audit is a window manufacturer, they'll try to sell you new windows. If they are a 3M distributor, they'll try to tell you window and door stripping. If they are the energy company... they might not tell you all you need to know.

I did a Google searc on "do it yourself energy audit" and found some good links. Here's one:

Most are free and well worth the time.
