They were great. They were super fast and easy to deal with. They sent me a report w full details and explanations same day or day after. Pretty impressive. Only reason for not a perfect score is that I discovered a closet without a key in the loft ( not exactly obvious ) and noticed the furnace air intake was secured with duct tape ( a nono ) and just a tiny bit loose. Noe of these were in the report. Again almost perfect score.
