We had a problem and we didn't know what the fix was, and KDC came in and diagnosed something that was really really simple, since we were new homeowners and didn't know where anything was. So rather than saying, "You need this, you need that," all they said is, "This is all we really need to do," and they charged me for just a service call. Which was really nice of them, because they could obviously have gotten away with a lot more. I would definitely use their services again.
