RJ and Alex were early, which was a good thing because the job took 5 1/2 hours, approximately. The equipment was amazing; a HEPA vacuum strong enough to get out debris from ductwork all over the house. All debris was carried through their own portable ductwork that was attached to the large vacuum. RJ and Alex were courteous and very professional. The job was described beforehand and the cost, as well. Since I had miscounted the number of vents by quite a bit, the job was more than the estimate I got over the phone. I did not fault them for my error, and was still satisfied with the price for the work involved. When the job was finished, RJ went through the house checking that everything was in order. The mold preventative they sprayed in the ducts after they were cleaned left the house smelling fresh and clean. I would not hesitate to give them a top recommendation.
