Confirming: duct cleaning MFs. When I asked for a number to call back and arrange an appointment - another person (called himself Steven) picked up a phone and gave me 647-656-5775. At that number an elderly lady (Nancy) didn't hear anything about cleaning.
this # called a few times, glad I looked up here what they are. I'm not picking up the phone, if I don't know the number. Stupid Duct cleaning scammers
