About Us


Personalized Approach

For three generations, dating back to 1946, AWC Air Duct & Window Cleaning has proudly served the Bay Area with exceptional care and quality. It all began with the vision of founder Frank Frediani, continued by his son Ron, who transitioned from a role in San Francisco's Window Cleaners Union to help lead AWC. Today, Ron and his wife Carol, along with their son Joe, own and operate AWC. Our highly skilled team is committed to delivering top-quality service safely and efficiently. As a family-owned business, we prioritize exceptional customer service, guaranteeing punctuality, tidiness, and a consistently courteous approach.

Excellence and Professionalism

To ensure your complete peace of mind, we maintain comprehensive liability insurance and workers' compensation coverage for all our team members. Upon request, we can readily provide a certificate of insurance.

We are proud to be active participants in the International Window Cleaning Association, which not only keeps us abreast of the latest industry innovations and techniques but also offers valuable ongoing safety training. Our team holds certifications in OSHA safety protocols and is duly trained and certified in aerial work platform operations.

Ron Frediani is an active member and has served on the board of the Millbrae Chamber of Commerce,  as well as an active member and past president of the Millbrae Lions Club.
