A duct system in Sewickley 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.
A separated joint in a Sewickley basement or attic does not just lose air - it loses heated air you paid to warm, all winter long. Rooms over the garage or at the end of long runs stay cold, the furnace runs longer, and the cause is usually a handful of failed seams rather than the furnace itself.
Northeast homes get renovated in layers - kitchens, baths, finished basements - and every project loads the ductwork with drywall and plaster dust if the system ran during the work. That fine dust packs into the trunk and blows out for years unless the system is cleaned from the trunk out.
A Pennsylvania 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.
Floor-level returns in Sewickley homes collect pet hair and dander faster than any filter can catch up with, especially in homes where animals have the run of carpeted floors. The buildup mats inside the return runs and is the first thing most owners see on the inspection camera.

Every Sewickley visit runs the same way — booked in one call, checked inside the ducts, and finished with the before-and-after shown to you, not just described.
Call (888) 258-5005 and tell us what the house is telling you — dust that comes back within days, rooms that never quite cool, airflow that feels weak. We book a local Sewickley tech, same day whenever a slot is open.
The visit starts with a look inside the ductwork — at the registers and at the main trunk — so the diagnosis is something you can see for yourself, and the inspection is free.
A negative-air machine seals onto the main trunk and pulls debris out under vacuum while each register is cleaned in turn, so the dust leaves through the machine — not into your Sewickley home.
You see inside the ducts before we start and after we finish, and any work beyond the cleaning is priced and agreed before it begins. Estimates are always free.

That is a summer of dust sitting inside the ductwork getting its first blast of heated air. In Sewickley it happens every fall. The smell tells you the trunk and returns are loaded; a cleaning from the main trunk out, done before the season starts, means the first heat cycle blows clean air instead.
Our negative-air machine seals onto the main trunk duct and puts the whole system under suction first. Then each individual run is scrubbed on its own, so loosened dust travels toward the trunk and into the machine - never back into your rooms. Registers are finished last, and you see the before-and-after on camera.
If you also have central air, yes - many Sewickley homes cool through ductwork added long after the house was built, often in the attic. Those systems collect the same dust and pollen as any other, and the attic runs are worth a camera look even if the radiators handle the heat.
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 Sewickley homes, failed tape and separated basement joints are the usual culprits, fixed properly with mastic sealing.
Yes - offices, retail, restaurants, schools and multi-unit buildings across Sewickley, 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.
