Yes it's for air duct cleaning, It's been going on for years. One of the reasons why they get away with it is. They call from India and they spoof local 416 and 905 numbers. If you call the number back this is why you get the message "This number is not in service." Last night the CBC Marketplace did a 2 part show on
telemarketers. Here is the link http://www.cbc.ca/news/business/story/2013/01/10/marketplace-offshore-telemarketers.html
Next week is part two of the show.

came up on caller ID as 011-416-555-9151...maybe some long distance routing...not sure.I have been getting repeated calls from Air duct Cleaning Services. ?The moment I ask where is your office or any details they hang-up.I have repeatedly requested to be removed from thier call list and told them I am on the do not call list.Anytime those things are mentioned, the caller hangs up.

I too have had calls from (416) 333-9151.  Perhaps it is a cell phone.  The caller says they are calling about duct cleaning in my area.  Today there was a free offer.  Sadly I missed hearing the name of the company clearly.I have had calls from the same caller (same voice) about duct cleaning from other numbers:Unknown Name(416) 743-7972Unknown NameLI +1 888-895-0222(250) 453-2289 (in the name space)LI 250-453-2289 It is always a pitch for ductcleaning - I have hot water heating and I do not have ducts.  When I tell them I have not duct they hang up instantly, without any closing courtesy.Can anyone suggest how to find the caller and charge with something?  He is a pest!
