Diamond Certified Researched Articles on AWC

AWC uses the newest equipment from Rotobrush to clean its customers’ air ducts.

AWC cleans air ducts, dryer vents, windows, and gutters for residential and commercial clients in San Mateo County and San Francisco. The family-owned and operated company utilizes a variety of state-of-the-art cleaning equipment to complete jobs quickly and efficiently, 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.”

“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.”

While an airtight home is good for energy efficiency, it makes air quality a greater concern.

“Due to improvements in modern window and door technology, today’s homes are more tightly sealed than ever,” explains Joe Frediani, co-owner of AWC in Millbrae. “While this is good for keeping conditioned air inside the home, one drawback is the home isn’t able to ‘breathe’ very well. As a result, all the air that gets circulated through the HVAC system tends to stay inside, which can make it challenging to maintain a high level of air quality.”

This lack of ventilation is further exacerbated by the increased use of heating and air conditioning in today’s world. “Between heating in the winter and air conditioning in the summer, the HVAC systems in most homes are running all the time,” says AWC co-owner Ron Frediani. “This increased use means a greater amount of airborne particles being circulated through the system, which results in more dust accumulating in the air filter and ductwork.”

With this in mind, consider the following steps for maintaining air quality in your home:

Change your HVAC filter regularly. Filters should be changed in accordance with the manufacturer-recommended interval. For example, if your filter is rated for three months, be sure to replace it every three months.

Upgrade to a better filter. Standard 1-inch fiberglass filters only provide a minimal amount of filtration, whereas high-grade, pleated filters do a better job of capturing dust, allergens and other airborne particles.

Have your air ducts periodically cleaned. A home’s air ducts should be professionally cleaned every two to three years, and more often if there are inhabitants with severe allergies or respiratory issues. Remember, effective air duct cleaning requires the right equipment and techniques, so be sure to hire a certified professional for the job.

Maintaining customer satisfaction is a crucial aspect of any business, but it's even more important for air duct cleaning companies that have earned the prestigious Diamond Certified award. For AWC, the best way to keep customers satisfied is to offer them a versatile suite of services that aren't typically found in one place. “The fact that we clean everything from air ducts to windows essentially makes us a one-stop shop for home maintenance, which is helpful for people who want to get a lot of things done at once,” says co-owner Joe Frediani. “Plus, we offer a discount for ordering multiple services during one appointment, so it's a real win-win for our customers.”

AWC has been cleaning air ducts, dryer vents, windows, and gutters for residential and commercial clients in San Mateo, Santa Clara, and San Francisco Counties since 1946. The family-owned and operated company uses pressure washers and other state-of-the-art equipment to complete jobs quickly and efficiently, and it's available 24/7 for its customers' convenience.

Unlike less experienced air duct cleaning companies that lack the resources and training to offer responsive service, AWC is quick to reply to its customers and take care of their needs. “When a customer calls us, they talk to a live person who addresses their concerns and sends a technician in a timely fashion,” says co-owner Ron Frediani. “It's rare for us to not be on a jobsite within 48 hours of the customer's call. We just do our best to be there when they need us.”

Ultimately, the Frediani family sees AWC's seven decades of experience as its most important attribute. “We've been in business for 70 years, which is practically unheard of for home maintenance companies, so our customers have a lot of assurance that we'll be able to handle their jobs,” says co-owner Carol Frediani. “They know they can call us any time and we'll help them with their cleaning needs.”

Ron Frediani: Capable Expansion

By James Florence, Diamond Certified Resource Reporter

MILLBRAE — As second-generation owner of AWC, Ron Frediani hasn’t just maintained his family’s company—he has also managed to expand upon its capabilities. “My dad and uncle started AWC in 1946 and I started working for them in 1965,” he remembers. “Over time, we’ve branched out from mainly doing window cleaning to providing services like gutter cleaning and power washing. About 12 years ago, we added air duct cleaning to our repertoire. ...

It's nice dealing with kind of a family business so they don't have that corporate attitude. One time, when I had a very short amount of time before a big party, I noticed all the windows were dirty. I called them and they knew it was important and they worked around my schedule.
