It was not actually Sears company who come to your house to clean, they hire someone for you. Because i bought a Central air conditioning system with them they were will to give me 1 free duct cleaning service. They were great they had a great atitude and great service. The one free cleaning they gave me was even better then the serice that i paid for. I will call them again. Before my daughters allergies were really bad but after they cleaned it, her allergies got a lot better. I recommend this company!
