The technician Mario was polite and informative. He was careful with my home during his job. He asked me first before just going ahead with details. He explained to me how duct work functions in my home as well. I am better informed about the function of the details of the ductwork of my property. Yes, the air that I breath in my home is improved as no one has cleaned the ductwork in about 10 years or more. A worthy investment.
