This was an experience worth talking about. Technician Felipe arrives at appointment time. We discussed the scope of the work and he proceeded to drape the floors, put in corner guards where needed to keep the hoses from rubbing. Everything went like clockwork, before and after pictures were shown to me as work progressed. Duct access repairs were done in a professional manner. Felipe also cleaned the dryer vent, what a mess in there. I don't have a clue why I would ever use someone else given the cleaning technology used and professionalism of the technician.
