I had a friend use Safety King years ago and after being disappointed by other companies in the past I researched until I found Safety King’s contact information and I knew that was who I wanted to complete the job. I am so happy that I did! Marcus was very professional and on time and completed the job as promised. I had them clean my ducts, furnace, and dryer vent. The vacuum was so powerful that he found a toy tonka truck in the duct work that was left behind by the previous owners. I would definitely recommend them and use them again.
