Hello,
We're planning to have air duct cleaning done soon, and I've read through some advertisements and have more questions than answers.
#1. One guy claims that they use a 200HP "Monster Vac" - a unit on the truck of a car that stays outside the house, and is thus "mess free". They say that they're better than others because other companies use hand-held or indoor vacuums that are not as powerful and might leave some dust inside the house. Is that true?? Is the outdoor, truck-powered unit better than indoor ones?
#2. This guy (with the Monster Vac) says that in order to access the duct system from the outside, they need to create an "access door" or an "access panel" (for an additional charge). Could anyone explain what this is, please? How damaging is it to the house/duct system?
#3. They offer sanitizing for additional $40. Do you know what chemicals they use? How effective is it? Will this solution be spread around the air in the house once the AC is turned on?
#4. This same guy also told me that there is no such license for Air Duct Cleaning (in Nassau County, NY, anyway), and since their company only does Air Duct Cleaning, they are not licensed. He underlined several times that it's not because they don't want to you can't get one, but because there is no such license. He says that other companies have licenses because they offer other services that require licenses. But since this guy offers no other services, he's ok without a license. IS THAT TRUE?
Thank you so much for your replies! I greatly appreciate your help!!
