Endless research led me to hiring Advanced Furnace and duct cleaning. The office staff was awesome and a pleasure to deal with and the field technicians were great! Bill and his helper(forget his name sorry) answered my questions for 5 minutes straight with a smile on their face even though I'm a pain in the $@!#%! They showed me a video of my trunkline getting cleaned and let me look into the ductwork as well. They even washed all my air vent covers. They were amazing. I'll see you in 3 years. And you will be called next week to do my moms house in Monroe!
