Average Cost of Air Duct Cleaning in Long Island
In Long Island, the average cost of professional air duct cleaning ranges between $498 and
$604, depending on the home’s size and complexity. According to local service listings,
homeowners can expect to pay anywhere from $434 to $823 for a full system clean in a typical
two-story home with 10 to 15 ducts.
Some companies may charge a flat fee per system, while others base pricing on the number of
vents or square footage. For smaller homes, the cost can fall below $500, while larger residences
or homes with HVAC upgrades may see higher estimates.
Factors contributing to the price include:
- Number of return and supply ducts
- Type of HVAC system
- Accessibility of ductwork
- Level of contamination (e.g. dust, mold, pet dander)
For accurate comparison, always ask if quotes include both labor and materials and whether
duct sanitizing or deodorizing is part of the package.
Factors Affecting Duct Cleaning Prices
Understanding what drives HVAC duct cleaning costs helps you compare quotes more
confidently. Here are the major factors that affect pricing in Long Island:
1- Home Size & Number of Ducts
Most pricing is based on the number of ducts. The more vents and registers you have, the more
time and materials are needed. A home with 15 or more registers may cost more than average.
2-Labor & Accessibility
If technicians need extra time due to hard-to-reach ducts or tight utility closets, labor costs can
increase. Most quotes include labor, but be sure it’s explicitly stated.
3-Extent of Dust & Debris
If your ducts haven’t been cleaned in 5+ years, or if there’s visible buildup or pest debris,
cleaning will take longer and require more equipment, increasing the cost.
4-System Type
Homes with forced air heating systems, multiple zones, or complex duct layouts may incur
additional charges.
5-Extras & Add-ons
Most basic quotes do not include services like:
- Dryer vent cleaning
- Mold remediation
- Deodorizing or sanitizing treatments
These services are billed separately and may cost $129 to $234 per dryer vent, for example.
6-Location & Local Rates
Pricing varies by zip code within Long Island. Nassau and Suffolk counties may show slightly
different market rates due to demand, provider competition, and property type.
What’s Included in HVAC Duct Cleaning Services?
A standard air duct cleaning service in Long Island typically includes:
- Inspection of the HVAC system
- Cleaning of all ductwork: this includes both supply and return vents
- Removal of dust, pollen, debris, and dander using powerful vacuums and air whips
- Cleaning of registers and grilles (up to 15 vents included in most quotes)
- Disposal of removed contaminants
- Labor and setup time
High-quality providers will also offer:
- HEPA-filtered vacuum systems
- Negative pressure setups to ensure dust isn’t released into your home
- Documentation or before/after photos upon request
However, services like mold testing, rodent removal, or HVAC coil cleaning are typically not part
of the standard package and come at an additional cost.
Additional Services and Exclusions
When reviewing quotes, pay attention to what’s not included:
❌ Dryer Vent Cleaning
Although it’s part of the air system, dryer vents are priced separately, often costing $129–$234
per vent. This is crucial for fire safety but usually an optional add-on.
❌ Mold Remediation
If your duct system has signs of mold, remediation can be expensive. Some companies charge
by the square foot or by treatment type (UV light, biocide sprays, etc.).
❌ Commercial Duct Cleaning
Pricing structures for commercial ductwork are entirely different—often based on linear feet
or system size. Don’t expect residential pricing to apply to offices or restaurants.
❌ Repairs & Replacements
If damaged ducts or vents are discovered, repairs or part replacements are billed separately.
This may include sealing leaks or replacing flexible duct sections.
When in doubt, ask for a detailed breakdown of included services—and exclusions.
How to Get an Accurate Estimate in Long Island
To avoid surprise fees and ensure you’re comparing apples to apples, follow these tips:
✅ Ask for a Free On-Site Estimate
Many local pros in Long Island offer free walk-throughs or virtual inspections. This allows them
to check vent count, access issues, and the general state of your system.
✅ Verify Inclusions
A reliable quote should clearly state:
- Number of vents included
- Whether labor is included
- Any additional fees (e.g. fuel surcharges, access challenges)
✅ Ask for Itemized Pricing
Request a breakdown that includes base cleaning, dryer vents, sanitizing, and mold treatment if
needed.
✅ Get It in Writing
Ensure you get a written estimate before work begins. Reputable Long Island professionals will
provide documentation and explain each service line.
Tips for Choosing a Duct Cleaning Company
Long Island homeowners have plenty of options—but not all duct cleaning companies are
created equal. Here’s what to look for:
Certification & Insurance
Choose a company certified by NADCA (National Air Duct Cleaners Association) and fully insured.
Local Reputation
Look for Long Island-based companies with positive Yelp or Google reviews and a history of
work in your neighborhood. Local pros tend to know common HVAC layouts in the area.
Equipment & Methods
Ask if they use HEPA filters, truck-mounted vacuums, or negative-pressure systems. Avoid
companies that use basic shop vacs or only clean visible vents.
Transparent Pricing
Beware of “too good to be true” pricing (e.g. $89 whole-house specials). These often exclude half
the system or upcharge heavily on-site.
Service Scope
Ensure they offer related services like dryer vent cleaning or pest-prevention sealing if
needed. A full-service company saves time and scheduling hassle.
