AWC cleans air ducts, dryer vents, windows, and gutters for residential and commercial clients in San Mateo, Santa Clara, and San Francisco Counties. The family-owned and operated company utilizes a variety of state-of-the-art cleaning equipment to complete jobs quickly and efficiently (including the newest equipment from Rotobrush), and it also offers pressure washing services and is available 24/7 to answer customers’ calls.

Co-owner Carol Frediani says much of AWC’s seven decades of success can be attributed to its customer-oriented approach to cleaning. “This company was established in 1946, so we’ve spent many years developing a reputation for always being there for our clients. They know they can call us any time and we’ll be ready to help them with their cleaning needs, and they really appreciate that.”

AWC maintains a staff of highly skilled and experienced technicians, all of whom are trained to perform work that adheres to the company’s high standards. “We’re very particular about the people we hire,” affirms co-owner Ron Frediani. “Every technician we send to a customer’s home is polite, responsive, on time and professional. Regardless of what a client throws their way, they respond with cheer and get it done.”

Company Philosophy

“We have a lot of respect for our customers, so we care for their homes as if they were our own and do whatever it takes to ensure their satisfaction. Our ultimate goal is to make sure each client has the best possible experience, so if anything goes wrong, we’ll be right there to take care of it.”
