The short answer
Gowanus homes need air duct cleaning when there is substantial visible mold, signs of vermin, or excessive dust and debris in the ducts, not on a fixed calendar. All Star Chimney Sweep inspects first from our office on Henry St, then cleans the system only when what we find calls for it.
All Star Chimney Sweep cleans air ducts for homes across Gowanus, and our office at 543 Henry St keeps us close to the brownstones, rowhouses, and apartment buildings in the 11231 area. Duct cleaning isn't something every home needs on a schedule. Our approach starts with a look inside your system so you know what's actually there before any cleaning begins. If the ducts are in good shape, we'll tell you. If they're holding heavy dust, renovation debris, signs of pests, or visible mold, our certified technicians clean them out and show you the results.
When Duct Cleaning Is Worth Doing
The U.S. EPA advises cleaning air ducts when there is substantial visible mold growth, evidence of vermin, or excessive dust and debris. It also notes that duct cleaning hasn't been shown to prevent health problems. We think homeowners deserve that honest framing, so we don't sell cleaning as a cure for allergies or a routine chore.
In practice, these are the situations where Gowanus homeowners most often call us:
- Dust blowing out of supply registers when the system starts up
- Leftover drywall, plaster, or sawdust after a renovation
- Droppings, nesting material, or odors that point to rodents or insects
- Visible mold on duct surfaces, coils, or around registers
- Moving into a home where you don't know when the ducts were last checked
Duct Systems in Gowanus Homes
Many brownstones and rowhouses in the neighborhood were built long before central air existed. When ductwork was added later, it was often fitted into tight spaces: soffits, closets, attic crawl areas, and narrow chases between floors. Those runs can have sharp turns and long horizontal stretches where dust settles and stays put.
Pre-war apartment buildings bring their own patterns. A unit may have a retrofitted air handler serving only a few rooms, or ducts that pass through spaces shared with neighbors. Newer buildings usually have more straightforward layouts, but construction dust left in the system at move-in is common.
Renovation is one of the biggest factors we see. Gut work, floor sanding, and plaster repair all send fine dust into return vents if the system runs during the job or the registers weren't sealed. That debris then circulates every time the heat or air conditioning kicks on.
What Our Duct Cleaning Visit Includes
Every visit starts with an inspection so the work matches your actual system. Here is how a typical job goes:
- Inspection of supply and return registers, accessible duct runs, and the air handler area
- A clear explanation of what we found and whether cleaning is warranted
- Protection of floors and furnishings near work areas
- Mechanical cleaning of the ducts to loosen and remove built-up dust and debris
- Cleaning of registers, grilles, and return openings
- A walkthrough of the finished work and notes on anything that needs other repairs

A Note on Cheap Offers and Chemical Treatments
The EPA warns consumers to research the process before responding to very cheap advertised duct cleaning offers, and to be careful with chemical treatments such as sanitizers or sealants sprayed into ducts. We agree. We don't push add-on chemical treatments by default. If something like that ever comes up, we'll explain what it is and why, and it's your call.
Timing Your Cleaning and Checking Dryer Vents Too
New York City's heat season runs from October 1 through May 31. Late summer or early fall is a practical window for duct cleaning in homes with forced-air heat, so the system is clear before it runs daily. For homes that rely on ducts mainly for cooling, spring works well.
While we're there, it's worth having us look at your dryer vent. According to the U.S. Fire Administration, failure to clean is the leading factor contributing to clothes dryer fires in homes. Dryer vents in rowhouses and apartments often run long distances to reach an exterior wall, which makes lint buildup more likely.
