Duct Leakage Test Special

Free Duct Leakage Test

Leaking ducts can reduce HVAC system efficiency by as much as 40%. Unless you inspect a duct system for leaks, you may never know how much efficiency and money is being lost.

We test ductwork in residential HVAC systems for air tightness is essential to ensure a home will be energy efficient and comfortable. Tighter ducts help homes perform better by allowing conditioned air to travel to its intended destination. They also keep newly conditioned air from escaping to the outside of the home.


A white pickup truck with the "STEWART" logo on its side is parked in an outdoor lot. The truck is adorned with green lettering that includes a phone number: "925-427-5522," and a list of services: "Heating, Air Conditioning, Indoor Air Quality, Architectural Sheet Metal." Below the phone number, the text "Since 1974" is visible, and on the lower right, "Lic. #290747" is displayed. A silver car is parked in the truck's bed. In the background, there's a large building with multiple garage doors and other vehicles parked in the lot.
