Topclass air duct cleaning showed up early for our 7pm appointment which was good. 3 guys showed up, and were very nice to deal with.. courteous etc.
They used an air gun in each of our vents to blow the dust/material down toward the large vacuum pipe that they hooked up to both my cold air return and hot air vents. I've had duct cleaning before in my previous home.. and that company took the time to remove the cold air return vents (as the tool they use can remove some of the paint on the vents). The other company also used a wire brush to remove any cement & paint off the inside of the vents.. both not completely necessary, but a nice gesture.
Our job was an especially large one, as the builder was nice enough to leave large amounts of cement particles in two different sections of our cold air return lines. This would cause a problem for the duct cleaners as the cement would slowly move from section of the duct to next, when they blew it with the air gun... It would not easily make it to where they attached the vacuum pipe.
The guys were nice enough to cut additional holes to vacuum out the large masses of concrete out of my vents. They weren’t able to remove all of it.. but they did remove most of it. I would have liked to see all of it removed.. but I didn’t want to take up any more of their time.
They were nice enough to charge me the original quote of $135.. which for a house of 2700sqft was pretty good in comparison to other quotes I got.
Although they didn’t charge me, they did have a look at my furnace and did a light cleaning of it.
One small draw-back that I had from the experience was a cloud of dust that filled the house.. which I doubt could have been avoided…especially with the amount of material in my duct system. No chemicals or deodorizing sprays were used.
For the cost I would recommend TopClass as they were reasonably priced, and had a lot of patience with my requests.
