I recently had a full house cleaning and decided to have the air ducts done as well. I was amazed at the difference cleaning out the air ducts did! I have quality air filters, and after cleaning the air ducts, my 5 year old slept through the night! Don't know if that was a coincidence or not, but I am not going to question it. What I will do is have my air ducts cleaned more often than once every few years!!
Pros: carpets cleaned right the first time
