I read Sam's review and I decided I should post my own experience with the company. Two gentlemen came from the company and explain the entire cleaning process. I watch them hook-up the pipe in the basement and clean each vent throughout the house. They than went down to the basement and began cleaning the duct work. The use the whipper tool (some sort of black rubber tool) in the duct work made alot of noise. They than tapped the duct work with a Hammer, and found some clunking noise in the duct work the gentlemen. Than made another small hole and began with the hammer tapping the debris out I was curious and asked him to remove the vacuum to see what comes out. He removed a giant 2x4 from my duct work ( I bought a brand new house). If he had not hit the duct work with the hammer he would have never discovered the piece. He than went onto the return side of the system. They removed all the grills from the side wall and sprayed in. I saw some dust blow back into the living room. He quickly cleaned it up.
The gentlemen than went down and clean the return side of the system. They even checked the smaller pipes. They spent over 2 hours in my house. My wife and me are very happy with the service and are glad the gentlemen took the time to check each duct and the small hammer tapping was not a bad thing in my view having good clean air to breathe is more important to me. He did tell me in some new homes the builders are using such thin metal sheets now a day simple tap causes some bending. I was lucky my builder used a better quality HVAC company to install my ductwork. Good job Unique keep up the good work will call in two years again!
