I called Safety King on Monday afternoon and Verna had Jason and Chris C out to the condo by Wednesday morning. On Tuesday I was sent a confirmation email with pictures of the technicians, which is a very nice feature. Upon arrival, 8 am, Chris and Jason explained the procedure, I showed them around and they went to work. The whole process took about 2 ½ hours including cleaning a second story dryer vent. Chris and Jason are both exceptional young men very polite, well-mannered, tidy and great representatives for Safety King. They even dusted a bit before they left. I would highly recommend both Safety King and these fine young men to anyone looking for air duct cleaning.
