These folks just called and offered to clean ALL of my air vents and duct work for $45. Seems like a good price for them to travel all the way from India. I don't know if their transportation and lodging are part of that price or if you have to cover that separately. If they call, just don't answer. The accent was hard enough to understand and the noise on the line sounded like the call was made in the middle of a monsoon.
