Vern and Timothy arrived at my home utilizing CDC guidelines, which I appreciated. They cleaned two drier ducts/vents for me. Both were very knowledgeable, thorough, friendly and kind. They let me know all they did and the process of cleaning. Before leaving I saw photos of how awful the ducts were. They also located a loose duct connection behind the stackable drier and connected it for me. I am very impressed with Safety King and will be contacting the office to schedule all my HVAC ducts to be cleaned. Thanks, Guys!!
