The short answer
AshVanta Chimney Services provides chimney inspections, sweeping, liner evaluations, dryer vent cleaning and air duct cleaning throughout Manhattan. The NFPA 211 standard calls for a chimney inspection once a year, and we recommend duct cleaning only when there is visible mold, vermin or heavy debris.
AshVanta Chimney Services cleans and inspects chimneys, flues, dryer vents and air ducts across Manhattan, from Roosevelt Island and Turtle Bay up through Harlem and Manhattanville. Housing here ranges from townhouses with working fireplaces to co-ops and rental buildings that share a boiler chimney, and each needs a different plan. Our certified technicians look at how your system is actually used, explain what they find, and recommend only the work it needs.
Annual Chimney Inspections and Sweeping
The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year, whether you burn wood every weekend or run a gas boiler all winter. Sweeping removes soot and creosote, which narrow the flue and can catch fire.
Inspections come in three levels. A Level 1 inspection covers a system that hasn't changed. A Level 2 inspection is needed when you add or replace an appliance, switch fuels, or buy or sell a home. A Level 3 inspection is for cases where a suspected hidden hazard can only be reached by opening part of the chimney or building.

Boiler Conversions and Chimney Liners
When a New York City building converts its boiler from oil to gas, the chimney has to be evaluated as part of the project. Gas exhaust produces acidic condensate that can corrode a masonry flue, so a new liner is often needed. We inspect the flue, document its condition, and explain whether relining makes sense.
The city's heat season runs from October 1 through May 31, when apartments must be kept at minimum temperatures. For that reason, owners usually schedule chimney and liner work for late spring or summer.
Dryer Vent Cleaning
According to the U.S. Fire Administration, failure to clean is the leading factor contributing to home clothes dryer fires. In Manhattan apartments and townhouses, dryer vents can run long distances through walls and ceilings, where lint builds up out of sight. We clean the full run from the dryer to the exterior and check that air moves freely. Signs your vent needs attention:
- Clothes take more than one cycle to dry
- The laundry area gets hot, or the dryer is hot to the touch
- Lint collects around the door or behind the machine
- You notice a burning smell while the dryer runs

Air Duct Cleaning, Done When It's Needed
The U.S. EPA advises cleaning air ducts when there is substantial visible mold, signs of vermin, or excessive dust and debris. It also notes that duct cleaning hasn't been shown to prevent health problems, and it cautions consumers about very cheap advertised offers and chemical treatments. We take the same approach. We inspect first, show you what's inside, and recommend cleaning only when conditions call for it. We don't apply any chemical treatment without explaining it and getting your approval.
