SECTION M1507 MECHANICAL VENTILATION

M1507.1 General. Where local exhaust or whole-house mechanical ventilation is provided, the equipment shall be designed in accordance with this section.

M1507.2 Recirculation of air. Exhaust air from bathrooms and toilet rooms shall not be recirculated within a residence or to another dwelling unit and shall be exhausted directly to the outdoors. Exhaust air from bathrooms and toilet rooms shall not discharge into an attic, crawl space or other areas inside the building.

M1507.3 Whole-house mechanical ventilation system. Whole-house mechanical ventilation systems shall be designed in accordance with Sections M1507.3.1 through M1507.3.3.

M1507.3.1 System design. The whole-house ventilation system shall consist of one or more supply or exhaust fans, or a combination of such, and associated ducts and controls. Local exhaust or supply fans are permitted to serve as such a system. Outdoor air ducts connected to the return side of an air handler shall be considered to provide supply ventilation. M1507.3.2 System controls. The whole-house mechanical ventilation system shall be provided with controls that enable manual override. M1507.3.3 Mechanical ventilation rate. The whole-house mechanical ventilation system shall provide outdoor air at a continuous rate of not less than that determined in accordance with Table M1507.3.3(1).

Before 1968, the New York City Building Code permitted air within hallways to be exhausted, so in a 1920s building, the hallway exhaust fans are competing with the exhaust fans in the apartment bathrooms and kitchens. If the exhaust fans in the apartments are stronger than the ones in the hallways, the stack effect will be exacerbated, drawing in odors (and in case of a fire, smoke) from the corridors into apartments. To alleviate the stack effect, an air-supply system can be installed in the hallways to deliver outside air into the building, providing positive air pressure in the hallways. (Heating and cooling coils would be required for the new air-supply fan system to temper the outside air supply.)

Frequently Asked Questions about Air Duct Cleaning

What is "air duct cleaning" and why is it important for homes in Long Island / Queens / Brooklyn / Bronx / NJ?

Air duct cleaning is the process of removing dust, debris, allergens, mold or other contaminants from the ventilation ducts and HVAC system of a building. Over time, ducts can accumulate dust, pet dander, mold spores, pollen, and other particulates — especially in dense urban/suburban areas like NYC and New Jersey — which may circulate through indoor air whenever the HVAC system runs. Cleaning ducts helps improve indoor air quality, reduce allergens and pollutants, eliminate stale or musty odors, and support healthier indoor environments for residents.

How Often Should Air Ducts Be Cleaned Inside an NYC / Long Island / New Jersey Home?

There is no "one-size-fits-all," but many experts recommend a professional duct cleaning every 3–5 years under normal conditions. However, in certain situations — such as if the home has pets, occupants with allergies or asthma, heavy dust, recent renovation/construction, or visible mold/pest issues — more frequent cleaning (e.g., every 1–2 years) may be advisable.

What are the top advantages for deciding to hire a professional air duct cleaning service over doing it myself?

Thorough cleaning: Professional cleaners use specialized tools — high-powered vacuums, rotary brushes, air whips — to reach deep into ductwork where regular household tools can’t reach.
Better indoor air quality: Proper cleaning removes dust, allergens, mold spores, pet dander, and other contaminants — which helps reduce allergy or respiratory issues.
Increased HVAC efficiency: Clean ducts facilitate better airflow, meaning the HVAC system works more efficiently — which can lead to energy cost savings.
Odour removal & prevention: Cleaning helps eliminate musty or stale odors caused by dust, debris, mold, or stale air in ducts.

Longer system lifespan: Regular maintenance reduces wear and tear on HVAC components and can prevent issues related to dust accumulation or contamination.

What are signs that my air ducts need cleaning now ?

Some common indications include:

  • • Musty, stale, or odd smells when the HVAC is on.
  • • Visible dust, debris, or mold around vents or returns; or dust blowing out of vents when system starts.
  • • Occupants experiencing allergy or respiratory problems that are getting worse, particularly inside.
  • • Recent home renovations or construction (which can introduce dust, drywall particles, sawdust, etc.) that may get into ducts.
  • • Presence of pets, smokers or other sources that generate hair/dander/residue over time.

What should I expect from a professional air duct cleaning service - process, cost, scope?

  • • A thorough cleaning often includes inspection, vacuuming of debris, dislodging dust using brushes/air whips, and cleaning all accessible ductwork.
  • • Many providers also inspect for mold, pests, or damage, and may offer supplemental services like sanitizing, HVAC coil/vent cleaning, or dryer-vent cleaning.
  • • Regarding cost in the New York / NYC area: typical residential air duct cleaning tends to fall roughly in the range of **US $267–$488** depending on size, number of vents, and complexity.
  • • Additional services (like coil cleaning, sanitizing, mold remediation) may increase the overall cost.

Is duct cleaning always required? Or can it be skipped if the ducts appear “fine”?

According to the U.S. Environmental Protection Agency (EPA), routine duct cleaning for every home is *not always* required. They recommend cleaning only when there is evidence of substantial contamination — e.g. visible mold growth inside ducts, presence of vermin, excessive dust or debris being released, or duct damage. If your home is well-maintained (regular filter changes, no moisture issues, no renovation or heavy dust, no pets or smokers), and there are no signs of contamination, frequent duct cleaning may not provide significant benefit.

Queens / Brooklyn / Long Island / Bronx / New Jersey - Is air duct service commonly available? Who commonly uses these services?

Many local providers in Queens, Brooklyn, Long Island, the Bronx, and New Jersey offer residential and commercial HVAC/duct cleaning services. Typical clients are: homeowners, apartment buildings, multi-family homes, offices, commercial establishments, and other buildings with central HVAC/ventilation systems.
