What Does Air Duct Cleaning Cost?
Professional air duct cleaning for a typical home costs between $300 and $700, with an average around $475. This covers cleaning the ductwork of a standard single-family home with roughly 10 to 15 vents. Some companies price per vent instead, often $25 to $50 each, dryer-vent cleaning runs $100 to $250, and sanitizing runs $200 to $550 per HVAC system. Where your cost lands depends on your home’s size, the number of vents, and any extras. Here’s how the pricing breaks down so you know what to expect.
Standard Whole-Home Cleaning: $300 to $700
The most common pricing is a flat rate for a whole-home cleaning, typically $300 to $700 for a standard single-family home with about 10 to 15 vents. This covers cleaning the supply and return ducts, the vents, and usually the main trunk lines. The range reflects home size and system complexity, a larger home with more ductwork and vents costs more. This flat whole-home rate is the simplest way duct cleaning is priced, and for most homes it’s the figure to expect, landing near the $475 average for a typical house. (For more on this, see How Much Does Duct Cleaning Cost?.)
Per-Vent Pricing: $25 to $50 Each
Some companies price by the vent rather than a flat whole-home rate, often charging $25 to $50 per vent (register). Under this model, your cost is the per-vent rate times your number of vents, so a home with more vents costs more. Per-vent pricing can be transparent, you know exactly what drives the cost, but watch for a low per-vent rate paired with a minimum charge or add-ons that raise the total. Whether flat-rate or per-vent pricing is better value depends on your home, so it’s worth understanding which model a company uses when comparing quotes.
Common Add-Ons: $100 to $550
Beyond the basic duct cleaning, common add-on services are priced individually. These include dryer-vent cleaning at $100 to $250 (important for fire safety and dryer efficiency, and often about $100 when booked alongside the duct cleaning), sanitizing or antimicrobial treatment of the ducts at $200 to $550 per HVAC system, and sometimes cleaning of additional components. These extras are optional and add to the base cost, so a quote with several add-ons runs higher than a basic cleaning. Some add-ons, like dryer-vent cleaning, offer real value; others may or may not be necessary for your situation. Understanding that add-ons are separate from the base cleaning helps you evaluate a quote and decide which extras you actually want. (For more on this, see What Affects the Cost of Duct Cleaning?.) The U.S. Fire Administration found failure to clean was the leading ignition factor in home clothes dryer fires, at 31 percent.
What Else Affects the Cost
Beyond home size, vent count, and add-ons, several factors shift the price. The number of HVAC systems matters, a home with multiple furnaces or air handlers has more ductwork to clean. The condition and accessibility of the ducts affect labor, heavily soiled or hard-to-reach ducts take longer. The level of service and equipment used varies between companies. And your location affects rates. These factors explain variation between quotes, which is why the range spans $300 to $700 rather than a single figure. The EPA makes no blanket recommendation for routine duct cleaning, advising it mainly for visible mold, pest infestation, or heavy debris.
Understanding What’s Actually Included in a Cleaning
When you compare duct cleaning quotes, one of the most important things to pin down is exactly what the price covers, because “duct cleaning” can mean very different amounts of work depending on the company. A thorough, legitimate cleaning typically includes cleaning the supply and return ducts, the individual vents and registers, and the main trunk lines, using professional equipment that reaches into the system to dislodge and extract accumulated debris. A cheaper, more superficial service might only clean the visible register areas or do a quick vacuum pass that doesn’t reach deep into the ductwork. Two quotes that both say “duct cleaning” can therefore represent quite different scopes of work, which is why the price alone tells you less than the price paired with a clear description of what’s included. (For more on this, see What Makes Air Duct Cleaning Cost More (or Less)?.)
This is why understanding the scope behind a quote matters as much as the number itself. A quote near the middle or upper end of the $300 to $700 range from a company that cleans the whole system thoroughly may be better value than a lower quote from a company doing a superficial pass, since the cheaper job may leave much of the system uncleaned. When comparing, ask each company specifically what their price includes, how many vents, whether the trunk lines and returns are cleaned, what method they use, so you’re comparing equivalent scopes. A well-defined, all-inclusive quote for thorough work is what lets you judge whether a price represents genuine value, rather than being drawn to a low number that reflects a job only half done.
Getting an Accurate Price
Because duct cleaning is priced by home size, vent count, and any add-ons, an accurate cost depends on your specific home and what services you want. A standard single-system home runs near the $475 average; a larger home, more vents, or several add-ons pushes toward the top. When you’re ready for a real quote, connect with a local pro below.

Frequently Asked Questions
For a typical single-family home with about 10 to 15 vents, $300 to $700, averaging around $475. Some companies price per vent instead (often $25 to $50 each), dryer-vent cleaning runs $100 to $250, and sanitizing runs $200 to $550 per HVAC system. Your cost depends on your home's size, number of vents, and any extras.
Most commonly as a flat whole-home rate ($300 to $700 for a standard home), which covers the supply and return ducts, vents, and usually main trunk lines. Some companies price per vent instead (often $25 to $50 each), so your cost is the per-vent rate times your vent count. Add-ons are separate: dryer-vent cleaning $100 to $250, sanitizing $200 to $550 per HVAC system.
An alternative model where a company charges per vent (register), often $25 to $50 each, so your cost is that rate times your number of vents. It can be transparent, but watch for a low per-vent rate paired with a minimum charge or add-ons that raise the total. Whether flat-rate or per-vent is better value depends on your home, so understand which model a company uses.
Dryer-vent cleaning (important for fire safety and dryer efficiency), sanitizing or antimicrobial treatment of the ducts, and sometimes cleaning of additional components, typically $100 to $250 for a dryer vent and $200 to $550 per system for sanitizing. These are optional extras separate from the base cleaning, so a quote with several add-ons runs higher. Some, like dryer-vent cleaning, offer real value; others may not be necessary for your situation.
The number of HVAC systems (multiple furnaces or air handlers mean more ductwork), the condition and accessibility of the ducts (heavily soiled or hard-to-reach ducts take longer), the level of service and equipment used, any add-ons, and your location. These explain variation between quotes, which is why the range spans $300 to $700 rather than a single figure.
