Bill T and DJ were on time, friendly, hard-working, knowledgeable, courteous, and professional. I know the difference because several months ago, I made a mistake and choose a competitor to “clean” our ducts and then suffered cold-like symptoms for over three months. When it finally occurred to me that dust in the ducts was causing me to sneeze and be stuffed up, I called Safety King. What a difference they made. Their photographs showed that the other company failed to clean all of the returns and left debris in the other ducts (including a red children’s ball!). In addition to the expert cleaning of the ducts, they also did the small things like wiping down the furnace and the room where it’s located. When they cleaned and packed up all of their gear more than 4 hours later, our home looked as good as when they came. And within hours my head started to clear up. I highly recommend them and would never use any other company than Safety King.
