Tony (Anthony) and Patrick did an awesome job cleaning our air duct. They are VERY courteous and very knowledgeable about the work. They showed before and after pictures. They run the number and confirmed with us about the things that we’d like to be done before they did the work. And make sure we have the internet coupon. I have work with lots company at this time doing house improvement and very rare they would do this. They did miss 1 of our supply vent (we are in the middle of moving in so we have boxes all over the place), I called the customer service and Tony came back the next day to clean it. Safety king is a great company and a pleasure to deal with. Thank you Safety King and especially to TONY and PATRICK!
