Our ducts hadn’t been cleaned in the 60+ years that our home has been around, and Safety King did a great job of getting everything cleaned out. Bill was kind and professional. He even took his shoes off when he came into the house. I enjoyed seeing the before and after pictures – well, I’m not sure if “enjoy” is the right word, but it was helpful to know. If you have an older house, there is probably some very nasty debris in your air ducts. If you’re looking to get them cleaned, definitely go with this company.
