I found Air Force duct cleaning through Homestars and I would recommend them. I spoke with Adel who was able to walk me through the process and services provided in great detail. He was able to answer several questions that I had. Dino came to our house to do the cleaning and he was fantastic! He was so thorough, took the time to explain absolutely everything to us, and showed us some great tips and tricks as well.
Although Air Force was not the cheapest quote I received, I was confident I would get a complete service for the amount I paid. Several companies I contacted could not give a concrete cost, some warned that the price could be higher depending on the actual amount of vents cleaned, and others had "bait and switch" type prices that seemed very low until you asked for more details (and the price increased significantly). There were no surprises with Air Force and I really liked that. They were very honest and transparent about their pricing!
