Jerusalem Duct Cleaning

I had purchased the groupon for the duct cleaning. The only thing I was charged extra was because they had to cut an opening for them to insert their vacuum into our ducts. I am more than please with the result of the duct cleaning. They explained to me exactly what they did and used antibacterial solution to clean the vents. I watched them myself and saw them removing all the vents in our home and inserted the vacuum tube inside. My wife and I definitely noticed and smelled the difference after the cleaning. My daughter was a little scared of the loud noise but he was nice enough to stop the vacuum until my wife was able to bring her downstairs so she wouldn't be as scared. Very friendly and courteous. I would definitely use them again in the future and would highly recommend them to others.
