Quality Air Duct Installation

If you are like most home and business owners, as long as your cooling and heating system is keeping you comfortable, you usually don’t give it much thought. However, what you don’t see could be costing you money. Most duct systems are installed in attics or in the crawl space where they are rarely seen or inspected. They may have been poorly sealed when installed, fittings may have come loose, and duct runs may have become disconnected. It’s not uncommon to see ducts torn apart or disconnected by rodents, or completely crushed after the “cable-guy” crawled through. All of this leads to a lot of lost air – air that you pay to heat or cool.

In fact, as much as 35 percent of a home or businesses heating/cooling airflow could be leaking through the ducts, causing a loss of comfort and cooling capacity. On average, almost 15 percent of cooling energy is wasted due to duct leakage.

Our service area encompasses all of Santa Cruz, Marin, Santa Clara, and Sonoma, and Marin County. We service all type of ducting and insulation: spiral ducting, AlumaFlex, sheet metal ducting, and more. From the most complex installation to routine service and maintenance we will handle the project from start to finish. Including removing and recycling of old ducting and sheet metal. Give us a call at 831-244-6718 and receive the best air duct installation in Santa Cruz, Marin, Santa Clara, and Sonoma.

Duct Damage and Leaks

The duct will typically leak at connection points. There is a common test that can be performed called a HERS test that can determine the amount of air leakage. These test typically run about $300 to $500 and take about 2 hours to complete. A little self-diagnostic can also help find leaks. The first thing to look for is disconnected ducts, such as the one shown below. If you ducts are wrapped in fiberglass, a good indication that you have a leak is any black or gray markings in the insulation. The fiberglass acts like a filter as hot or cold air is pulled into the duct by the air handler fan. Another good place to inspect is around register cans. We typically find about 5 to 10% air leakage here. Apply mastic or use butyl tape to seal these areas.

Find out why we’re considered the favorite plumbing service in the Bay Area by our satisfied customers!

Octavio, Danny, Alex, and electrician Tom did an excellent job installing our split A/C units. Octavio also set up remote access on my smartphone, a first-time experience for him. The team was efficient, neat, and worked seamlessly together, answering all my questions throughout the installation.

Jeremy was exceptionally friendly, knowledgeable, and professional—a pleasure to work with. Bellows consistently stands behind their products, and this experience solidified my loyalty. I’ve always had positive interactions, but this one truly made me a customer for life.

The technicians provided excellent customer service, taking their time to replace our unique direct vent water heater. It was a special order that required expert installation, and they did a fantastic job. Very pleased with the results—thank you, Bellows, for your outstanding work!
