What affects your air duct cleaning price?
- Number of vents/registers, more supply and return vents means more labor.
- Home size & number of systems, a second HVAC unit roughly adds another system’s worth of work.
- System access, hard-to-reach ducts, attics, or crawlspaces take longer.
- Level of contamination, heavy debris, pet dander, or mold may require extra treatment.
- Add-on services, bundling dryer vent cleaning or sanitizing.
Why “$99 air duct cleaning” is usually a scam
Ultra-low “whole-home” prices are typically a “blow-and-go”, a quick once-over used to upsell you on site, not a real source-removal cleaning. A thorough job uses negative-air equipment and takes hours. If a quote seems too good to be true, ask exactly what’s included and whether they follow EPA practices.

FAQ
Air duct cleaning cost: FAQ
How much should air duct cleaning cost in the Raleigh area?
For most Triangle homes with one HVAC system, expect roughly $400–$1,000, commonly $450–$650. Larger homes, multiple systems, or mold treatment cost more. See Raleigh pricing or Cary pricing.
Is air duct cleaning worth the money?
It’s worth it when there’s mold, pests, heavy debris, or post-renovation dust. For an already-clean home it may not be necessary. See our honest guide: is air duct cleaning worth it?
Do you charge per vent or a flat rate?
We price by your home’s size, vent count, and system access so the quote reflects the real work, not a bait rate. Every quote is itemized.
How much does air duct cleaning cost per vent?
Reputable companies price by system and home size rather than a low per-vent teaser. Be cautious of “$99 whole-home” offers, they typically lead to on-site upsells. Ask for an all-in quote based on your actual system.
What moves the price up or down
Two houses on the same street can get quotes hundreds of dollars apart, and both can be fair. These are the factors that legitimately change the number:
- Vent and return count. Every supply register and return grille adds time, this is the single biggest driver.
- Number of HVAC systems. Two-system homes (common in larger two-story houses in Cary and North Raleigh) are close to double the work.
- Duct access. Runs through tight crawl spaces or hot attics take longer than open basement runs.
- Condition. A system that has never been cleaned, or one full of renovation dust, takes more passes than light routine buildup.
- Add-ons that make sense together. A dryer vent cleaning bundles cheaply (about $100) because the crew is already on site; coil cleaning and sanitizing are priced by scope.
How to compare quotes without getting burned
Compare scope, not just the bottom line. A quote that includes all supply and return runs, the main trunks, registers, and before-and-after photos is a different product from a “per-vent special” that surface-cleans what you can already see. Ask each company the same three questions: what exactly is included, what equipment do you use (source removal means negative-air machines and agitation tools), and will I get photos of my own ducts? Our guides on duct cleaning scams and choosing a company cover the red flags in detail.
One more honesty check: the EPA does not recommend cleaning on a fixed schedule for its own sake, it is warranted when there is substantial visible debris, mold, or pest activity, after major renovation, or when airflow and dust problems point to buildup. A company that inspects first and tells you when you don’t need a cleaning yet is the company to keep. For Raleigh-specific pricing see our Raleigh cost guide; we serve Cary and the wider Triangle with itemized quotes after a real inspection, never a phone-script price.
More common questions
Why is there such a big range in duct cleaning prices?
Because homes differ that much. A 1,400 sq ft ranch with one system and 10 vents is a few hours of work; a 3,500 sq ft two-story with two systems and 25 vents can take most of a day. Vent count, system count and access explain nearly all of the spread among honest quotes.
Is air duct cleaning worth the money?
It depends on your home’s condition, and an honest company will say so. It is worth it when there is real buildup, post-renovation dust, mold, or pest debris in the system. It is not worth it as an annual ritual for a clean system. Our guide “is dryer vent cleaning worth it?” takes the same honest approach for dryer vents, which do need annual attention.
Does the price include the dryer vent?
Usually not by default, but bundling is the cheapest way to get it done, typically about $100 extra when added to a duct cleaning, versus a standalone visit. Given that lint-clogged dryer vents are a leading contributing factor in dryer fires, we recommend bundling if yours has not been cleaned in over a year.
