New Duct Installation & Sealing

New Duct Installation & Sealing is one of the most impactful services we perform on residential and commercial HVAC systems — and one of the most misunderstood. The average U.S. home cycles the same air through its ductwork 5–7 times a day; the average home loses 25–40% of conditioned air to leaky, undersized, or poorly-sealed ductwork. When ducts are dirty, every one of those cycles pushes dust, allergens, pet dander, mold spores, and combustion byproducts back into the room you're breathing in.

Our approach to new duct installation & sealing starts with a full visual and camera-scope inspection of your supply and return runs, the plenum, the blower, and the coil. We never quote blind over the phone, because a "dusty vent" can mean a construction-debris load, biofilm from a humid attic, a rodent nest in a distant branch, or a collapsed inner liner in a flex run. A real inspection takes 20–30 minutes; a wrong guess can cost you money you didn't need to spend.

Once we identify what's actually in the system, we walk you through it with camera stills or short video clips. You'll see exactly what's coating the interior walls, the register faces, and the coil fins, hear what your options are, and get a flat written price before any hoses come off the truck. We arrive with truck-mounted or portable HEPA-filtered negative-air machines rated for 5,000+ CFM, agitation whips, rotary brushes sized for your specific duct diameter, contact-vacuums, and NADCA-approved sanitizers when they're indicated. That means 95% of jobs are completed in a single visit.
