"I noticed this deal of Air Duct cleaning for unlimited vents and called Angies List customer service to ask about the deal and make sure that my one furnace with 3 zones would fit this deal and got all my questions answered; then I purchased the service deal and within an hour or so, I was called by the service company (LOWE'S Air Duct Cleaning Inc) and told that they are working in my area today, and have an opening in the middle of the day since someone changed their appointment; I accepted the time; the service man (Milo) came on time, worked non stop for about 3 hours, where he opened each air vent for the incoming and returned air and cleaned. I have asked for a camera to be used in 3 air vents in order to see before and after cleaning, and noticed the difference. Milo was extremely kind, professional, and worked very hard to get things done in a reasonable amount of time given that I have about 27 air vents and returned air plus 4 long ducts in the basement that are coming from an into the one furnace; The service also included sanitizing and air freshening. I was extremely satisfied with the service, and would defenetly recommend the service to anybody."
