Local conditions

Larchmont ducts have Larchmont problems

A duct system in Larchmont 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.

The first-heat dust smell

Every fall in Larchmont, 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.

Heated air leaks cost the most here

A separated joint in a Larchmont 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.

Renovation dust never really leaves

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.

Cold rooms at the end of the run

The bedroom over the garage, the addition at the back - Larchmont homes almost always have one room the system underserves. Crushed flex runs, long undersized branches and leaking joints are the usual findings, and the fix belongs to the ductwork rather than a bigger furnace.

Questions

Asked the way Larchmont asks

How often should ducts be cleaned in the Northeast?

Every few years suits most Larchmont homes - sooner after a renovation, with shedding pets, or when allergy symptoms track with the system running. We camera-inspect free and show you the inside of your own trunk, so the decision comes from what is actually in there.

How do you clean the ducts - what is the process?

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.

My home has radiators - do I still have ducts?

If you also have central air, yes - many Larchmont 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.

What are the signs my ducts are leaking?

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 Larchmont homes, failed tape and separated basement joints are the usual culprits, fixed properly with mastic sealing.

Do you offer same-day air duct service in Larchmont?

Yes - same-day service is available in Larchmont, along with free inspections and estimates before any work starts. We are licensed and insured, with 10+ years of experience and 100+ 5-star reviews. Call early in the day for the best chance of a same-day visit, especially in the first cold weeks.

Do you give prices over the phone?

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.
