Our technician, Sani, did an excellent job cleaning out all our ducts, returns and two furnaces. While it's a very pricey job, they offer the best deal. Sani, spent the entire day cleaning and had lots of pictures to show us, that made me very happy we decided to have this job done! The air in our home smells much more fresh and our whole family is having significantly less allergy problems. Overall, a great service at a fair price.
