I think I've found the right company to install a heating system at my place. I got the technical information I was looking for.

But when I told the guy that proof of current licensure and liability insurance was needed, the guy on the other end of the line sounded miffed that I would even DARE to ask for such documents!

This company has been in town for many years, and I've done business with them in the past over relatively minor matters. But I think when it comes to something like a heating system with obvious consequences, does it not make sense that they fork over proof first that their license is current and have insurance?
