We have lived in our home for 15 years and decided to have our ducts cleaned. After talking to friends, many were disappointed becuase they had hired the coupon guys ($150.00) to clean all of their vents. Their service lasted about 1 1/2 hours. We hired ductworks who - yes was more expensive, Rudy was exceptional and spent over 9 hours at our home and what professionalism! He did a great job, showing us before and after photos. What a difference in the ducts and th furnace. I believe our home will be cleaner and have less dust and I believe our furnace and air conditioner will work more efficiently. I would recommend Ductoworks to anyone with extreme confidence. Keith & Diana Simpson - Parker C0
