A duct system in Old Westbury heats all winter, cools all summer and runs through basements, attics and wall cavities that were never designed for it. This is what we actually find here, and what we check on every visit.
Every fall in Old Westbury, the first furnace cycle blows a summer of settled dust off the inside of the ductwork and into the rooms. The burnt-dust smell fades in a day or two, but what caused it - a loaded trunk and dirty returns - stays in the system and recirculates all winter.
The main trunk in a typical Nassau County home runs across an unfinished basement, past laundry lint, workshop dust and storage shelves. Gaps at basement joints pull that air straight into the supply side, so the house ends up breathing the basement.
Tree pollen floods Old Westbury every spring and works into return ducts through open windows, then winter seals the house tight for months with the same air cycling through the system. The ducts become the reservoir that keeps last spring's pollen moving in January.
A New York summer is humid and the winter air indoors is bone dry, and the duct system lives through both extremes. Summer moisture in cool basement ducts feeds musty odors, while winter's dry air lifts fine dust off surfaces and into the returns - the system needs checking at both ends of the year.

Same-day service, free estimates, licensed & insured — and a air duct that lights when you click the remote.
Rooms that lag behind the thermostat, a furnace that runs in long cycles, dust that settles fast after cleaning, and supply registers that blow weakly at the far end of the house. In older Old Westbury homes, failed tape and separated basement joints are the usual culprits, fixed properly with mastic sealing.
It removes one real reservoir: pollen, dust and dander stored in the returns get recirculated every cycle in a sealed winter house. Families in Old Westbury often notice slower dust buildup afterward. It is not a medical treatment, but a clean system stops redistributing what has collected in it.
Yes - renovation dust is the heaviest load a system ever takes in. Drywall and plaster dust pack into the trunk during the project and blow out for years. A post-renovation cleaning from the trunk out, plus a fresh filter, closes the project out properly.
Yes - offices, retail, restaurants, schools and multi-unit buildings across Old Westbury, scheduled around your hours. Commercial systems get the same method: the negative-air machine sealed onto the trunk, every run cleaned individually, and a documented camera record of condition.

No — and be wary of anyone who does. Every duct system is a different size and condition, so a phone price is a guess that changes at your door. Our inspections and estimates are free: a tech looks inside your actual ductwork first, then gives you one clear price before any work starts.
