I never thought I could have such a pleasant experience with duct cleaning. Our dryer ducts were clogged and causing the fire alarm to go off from the high levels of humidity. We thought we might as well have the ducts to the whole house cleaned out too since they never have been. We hired Dave's Duct cleaning for both services. The two gentleman assigned to us arrived on time and started with the dryer. Our home has a very odd duct system and the guys had challenges ahead of them, including getting onto our third story roof in the winter to clean out the vents. A typical job would take them less than an hour, but because of the complications with our system, it took them two. They never complained, they explained everything they were doing as they did it, and even did a minor repair along the way free of charge that involved having to drive to our local home depot. We are so grateful to them, because other companies would have doubled the fee because of the added work and risk. Then when it came time to clean out the ducts, they discovered we had a high velocity system which doesn't involve the same amount of work on their part, so they did a quick clean up, showed us the before and after photos, and didn't even charge us for it! I have never dealt with such honest and conscientious contractors before. I absolutely recommend Dave's Duct Cleaning to anyone who needs this service.
