They are way better than the other duct cleaners and telemarketers. Macro duct cleaning people have good equipment because i am an engineer so i know what is what. I am pretty much satisfied with the work. I got my air duct & dryer vent cleaned by them. They suggested me to wait for a while for furnace cleaning because it was not dirty (Other companies never leave an upselling chance) So they are quite honest as well. I am happy with them. I have posted a picture of vent after cleaning.
