Duct testing and aerosol duct sealing

The duct testing page states that ductwork functions like the arteries that keep an HVAC system running properly, and that recent studies have revealed the ductwork in most U.S. buildings today loses 20% to 30% of treated air through leaks, which the page says both cost money and jeopardize the comfort and indoor air quality of a building.

It says the experts at BAB&C can swiftly and accurately measure the leakage rates of a duct system and determine whether the building complies with design specifications. If leakage rates surpass desired levels, the page says BAB&C can seal those leaks using the latest aerosol-based duct sealing technology developed by the U.S. Department of Energy. It states this approach allows the company to seal ventilation shafts and ductwork with minimal to no demolition or deconstruction, and that on completion the computerized process generates a final report certifying specification compliance.

The affiliations page lists Aeroseal among the associations the company holds membership in. Duct testing and sealing is one of the six services listed in the services menu, alongside cleanroom testing and adjustment, commissioning, mechanical test and balancing, sound and vibration testing, and water balancing.

The website gives no price, cost, rate or fee for duct testing or duct sealing, no figure for a typical project, and no stated leakage threshold beyond "desired levels". Anyone needing a quote or estimate is directed to contact the company on 408.330.0900 or at info@bayareabalancing.com.
