Safety King (Kathy, Bill, and Eric) cleaned our duct work and dryer vent. Professional, courteous, and very careful not dirty or damage the house, they explained, in detail, what they were doing and what tools were being using. I was able to see before and after photos of important parts and Bill patiently went through the checklist I had printed out from the National Air Duct Cleaners Association (NADCA) webpage – this checklist was also provided on Safety King’s website. Arriving on time, Bill and Eric finished the job in the amount of time quoted to me. A wonderful experience and clean ducts!!!
