Just had someone come to my door. He didn't say who he was with, or who he worked for but his jacket was labels as "go green" and had an energy Star Logo on it.

He claimed that there were recent building code changes that he had to come into the house and inspect my furnace and duct work to make sure it was up to code. Now I could be 100% wrong, but if that type of an inspection was needed a government body likely would have called, mailed, or some other way notified us and setup a time.

He showed up in the middle of dinner and Insisted he had to come in anyway, Bad tick number one. I told him I had just replaced my furnace a year ago, and they had told me everything was up to code at that time, He responded by saying that was maintenance and had nothing to do with the furnace at all. I asked him who sent him and he didn't answer, in all I told him no, and to get off my porch 5 times before he left.

It might not be a scam, but that sure felt like one to me.
