The short answer
Nexora Chimney Services cleans and inspects chimneys, dryer vents and air ducts throughout lower and midtown Manhattan. We follow the NFPA 211 yearly inspection standard, evaluate chimneys and liners for oil-to-gas boiler conversions, and recommend duct cleaning only when there is a clear reason for it.
Nexora Chimney Services cleans and inspects chimneys, dryer vents and air ducts in homes and buildings across Manhattan, from Chelsea and Hell's Kitchen to Tribeca and the Lower East Side. Manhattan housing ranges from brownstones with working fireplaces to large co-op and rental buildings with central boilers, and each needs a different approach. Our certified technicians start by looking at what you actually have. Then they explain what it needs and why.
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 light a fire only a few times each winter. Soot and creosote build up, mortar joints wear, and nests or debris can block a flue that sits unused for months.
Chimney professionals use three inspection levels. We use the one that fits your situation:
- Level 1: a routine yearly check when nothing about the system has changed
- Level 2: when you add a new appliance, switch fuels, or sell the home
- Level 3: when a suspected hidden hazard can only be reached by opening part of the chimney or building

Oil-to-gas conversions and chimney liners
Many Manhattan buildings are converting their boilers from oil to gas. When that happens, the chimney has to be evaluated as part of the work. Gas exhaust produces acidic condensate that can corrode a masonry flue, so a new liner is often needed. We inspect the existing flue, explain what we find, and install a liner when the flue's condition calls for one.
New York City's heat season runs from October 1 through May 31. During that time, building owners must keep apartments heated to the city's minimum temperatures. Scheduling inspections and liner work before October helps keep the boiler running when tenants depend on it.
Dryer vent cleaning
According to the U.S. Fire Administration, failure to clean is the leading factor contributing to clothes dryer fires in homes. In apartments and townhouses, dryer vents often run a long way through walls and ceilings before they reach the outside, which gives lint more places to collect. We clean the full run, not just the section you can see behind the machine.
It is time for a cleaning if clothes are taking longer to dry, the laundry area feels unusually hot, or you smell burning when the dryer runs.
Time for your annual chimney check?
Air duct cleaning, when it makes sense
We follow the U.S. EPA's guidance on duct cleaning. The EPA says it is worth doing when there is substantial visible mold growth, signs of rodents or insects, or excessive dust and debris in the ducts. The EPA also says duct cleaning has not been shown to prevent health problems, so we won't promise that it will.
Before you hire anyone, find out how the work will be done. Be cautious of offers that seem unusually cheap, and ask questions about any chemical treatment. We tell you up front whether we recommend a chemical treatment and why.
