Safety King came recommended to me – and they were more than worth the referral !!! Katherine explained things so well, that I knew exactly what would be done. The techs, Eric and Brendan, arrived exactly on time. They were courteous and treated my home with extreme care. I was amazed at the before and after pictures. My ducts look like new! They also offer other services that may be of interest. Other companies may be a bit cheaper, but I have talked to a lot of unhappy neighbors that used the cheaper companies. I am more than 100% satisfied and will not hesitate to recommend them!!
