Heating Duct Cleaning Cost Calculator

Heating duct cleaning costs vary widely depending on several key factors. On average, the cost ranges from about $450 to $1,500 for a typical home system, with some estimates as low as $300 and others reaching $1,500 or more for larger, more complex setups.

Factors Affecting Heating Duct Cleaning Cost

Factor	Description	Cost Impact
Size of the Home/Ductwork	Larger homes have more ductwork, resulting in higher costs due to increased time and effort required.	Costs increase with size, e.g., $755 for 1200 sq ft to $1500 for 2500 sq ft.
Type of Ductwork	Rigid ducts are easier and cheaper to clean; flexible ducts and complex systems require specialized tools.	Flex ducts typically increase price due to difficulty.
Degree of Contamination	Presence of dust, mold, mildew, or rodent infestations requires more intensive cleaning or remediation.	Mold remediation can add $1,000-$3,400; rodent removal adds cost.
System Accessibility	Hard-to-reach ducts (attics, crawlspaces, long runs) increase labor time and costs.	Inaccessible ducts increase labor charges.
Additional Services	Extra cleaning of components like furnace, blower, coils, or dryer vents; sanitization or duct repairs.	Adds hundreds of dollars depending on service scope.
Geographic Location	Costs vary due to regional market differences, labor costs, and demand.	Urban areas usually more expensive than rural.

Typical Price Ranges

Service Type	Price Range	Notes
Basic duct cleaning (average home)	$300 - $700	Includes ducts, vents; may exclude furnace/coil
Full HVAC system cleaning	$450 - $1,000	Includes ducts, registers, coils, heat exchanger
Homes 1,200 - 2,500 sq ft	$755 - $1,500 (may scale up)	Pricing often by square footage or number of vents
Mold remediation	$1,100 - $3,400	Additional cost when mold is detected
Duct repairs (holes, leaks)	$250 - $500+	Patch or seal leaks as needed

Breakdown of Cost Calculation Methods

Method	Description	Pricing Example
By Square Footage	Charged between $0.15 and $0.40 per sq ft of home size.	A 2,500 sq ft home might pay $375 to $1,000+
By Number of Vents	Charged per supply vent ($25-$50) and return vent ($40-$75).	10 supply vents × $40 + 3 return vents × $60 = $580
