Safety King did a great job. We have an unconventional home built by the previous owner so nothing is really as it should be. The ductwork in our house posed some problems but they were able to work it out and they did an amazing job. The before and after pictures speak for themselves. Again, great job. I highly recommend them to anyone. I did shop around and looked at other companies. But Im glad I chose Safety King. As the person on the phone said to me all they do is ductwork cleaning and it shows. They were definitely the right company to hire for this job. Thanks.
