The short answer
Air duct cleaning is worth doing when you can see heavy dust or debris in your ducts, after renovation work, or when pests or odors are coming from the system. ClearStack's certified technicians clean supply and return ducts, registers and accessible system parts with HEPA vacuums and rotary brushes, and they protect your home throughout the visit.
Your heating and cooling ducts move air through every room in the house, so dust, debris and anything else that settles inside them can end up blowing back out of the vents. ClearStack Chimney Service cleans residential air duct systems in Brooklyn and nearby parts of New York City, from rowhouses and brownstones to detached homes and multi-family buildings. We focus on problems you can actually see, smell or measure: dust puffing from registers, debris left behind after a renovation, signs of pests, stale odors and weak airflow. We don't claim duct cleaning will change your health. We clean what's there, show you what we found and explain how it went.
Signs you need it
Most homeowners call us because something about their vents has changed. The signs below are the ones that usually point to a real buildup inside the ductwork, not just normal household dust.
- Dust blowing from vents when the heat or air conditioning kicks on
- Gray, fuzzy buildup visible on register covers or just inside the duct opening
- Fine drywall, plaster or sawdust coming out of vents after a renovation or repair
- Scratching, scurrying or nesting noises in the walls or ceilings near ductwork
- Droppings, nesting material or insects found in or near registers
- Musty or stale odors that get stronger when the system runs
- Weak airflow in some rooms even though the system is running normally
- Visible mold growth on duct surfaces or around registers

What's included
Every air duct cleaning visit covers the parts of the system that move air into and out of your rooms. If we find something outside this scope, such as a damaged duct section or a problem with the equipment itself, we'll show you and talk it through before doing anything else.
- Walk-through of the home to locate every supply and return vent
- Protection of floors and furniture along the work path
- Removal and cleaning of supply registers and return grilles
- Brushing and vacuuming of supply ducts and return ducts
- Cleaning of the accessible blower compartment and plenum areas
- Check of the air filter, with a recommendation if it needs replacing
- Camera look inside ducts where access allows, before and after cleaning
- Note of any disconnected joints, crushed sections or signs of pests
- A plain-language rundown of what we found and what we did
How our crew works in your home
We put down drop cloths from the door to each work area and cover nearby furniture before any register comes off. The main cleaning tools are rotary brushes, which loosen dust and debris stuck to the duct walls, and HEPA-filtered vacuums, which capture what the brushes knock loose so it doesn't drift back into the room. We work one section at a time and seal off open registers as needed so debris moves toward the vacuum and not into your living space.
Where the layout allows, we run a camera into the ducts so you can see the condition before and after. Some Brooklyn homes have older or patched ductwork tucked behind finished walls, and the camera helps us spot disconnected joints or blockages without opening anything up.
If part of your system sits on the roof, in an attic or in a tight basement crawlspace, we check access when we arrive and work there with the same care, keeping hoses and equipment off finished surfaces. When we leave, registers are back in place and the work area is vacuumed.
Time for your annual chimney check?
The guidance we follow
Duct cleaning has no inspection standard like the yearly chimney inspection in NFPA 211, so we follow the U.S. Environmental Protection Agency's guidance. The EPA advises cleaning air ducts when there is substantial visible mold growth, vermin, or excessive dust and debris. It also says duct cleaning has not been shown to prevent health problems, which is why we describe our work in terms of what you can see and how the system runs.
The EPA also warns homeowners to research the process before responding to very cheap advertised offers and to be careful with chemical treatments. We don't spray sanitizers or coatings into your ducts as a routine add-on. If we find a situation where a treatment might come up, we explain what it is and leave the decision to you. If your ducts don't need cleaning, we'll tell you that, too.
What affects the price
Every home is different, so we look at the system before we quote. These are the main things that change the scope of the job:
- Size of the home and the number of supply and return vents
- How easy it is to reach the ductwork, including attic, basement, crawlspace or roof access
- How many floors the system serves and how the ducts are routed
- Duct size, material and condition, including older or flexible ductwork
- How much dust, renovation debris or nesting material has built up
- Whether a camera inspection is needed to locate a problem
- Whether repairs are needed, such as resealing joints or replacing a damaged section
How a visit works
You start by contacting us and describing what you're noticing, whether it's dust from the vents, noises in the walls or a recent renovation. We'll ask a few questions about the home and the system and set up a time that works for you.
When the crew arrives, they walk through the house with you, find all the vents and look at the equipment. They explain the plan and the scope before starting. Then they protect the work areas, clean the system section by section and check their work with the camera where possible.
Before leaving, the technician goes over what they found, shows you any photos or camera footage, and points out anything that needs attention, such as a dirty filter or a loose duct connection. Most homeowners can use their heating or cooling right after we finish.
