Air duct cleaning cost

Air duct cleaning costs $450 to $1,000 on average, depending on the home size, level of contamination, and ductwork accessibility. Some air duct cleaning services charge $25 to $50 per supply vent, while others use a duct cleaning price of $0.20 to $0.40 per square foot of home size instead.

Average cost of air duct cleaning by vents
Number of vents Average cost
8 $200 – $400
12 $300 – $600
16 $400 – $800
20 $500 – $1,000

The number and type of vents in a home affect the overall air duct cleaning cost. Larger homes have more vents than smaller ones, increasing the total cleaning costs.

  • Supply vents (where air comes out) typically cost $25 to $50 each to clean.

  • Return vents (where the air goes back in) can cost $40 to $75 each to clean, but the return vents are often fewer in number compared to supply vents.

Duct cleaning cost by square footage

The Environmental Protection Agency (EPA) and the National Air Duct Cleaners Association (NADCA) estimate air duct cleaning costs between $450 and $1,000 for an average-sized home. Some companies base their prices on square footage, charging $0.20 to $0.40 per square foot. This means larger homes pay more for air duct cleaning than smaller homes.

Duct cleaning price by home size
Home size (square feet) Average cost
1,200 $240 – $480
1,500 $300 – $600
2,000 $400 – $800
2,500 $500 – $1,000
3,000 $600 – $1,200

Duct cleaning price factors

In addition to home size and the number of vents, other factors can influence the cost of air duct cleaning services, including:

  • Location: The cost of duct cleaning services can vary depending on the region or location, as labor and overhead costs may differ.

  • Type of ductwork: Certain types of ductwork, such as flexible ducts or older ductwork, may require more gentle cleaning methods or additional precautions, which can affect the overall cost.

  • Ductwork accessibility: Difficult to access ductwork, such as in tight crawl spaces or behind walls and ceilings, can increase the labor time and complexity of the job, resulting in higher costs.

  • Level of contamination: Ductwork that is heavily contaminated with dust, debris, mold, or other pollutants will require more intensive cleaning efforts, which can increase the cost.

  • Cleaning method: Different cleaning methods, such as rotary brushes, compressed air, or mechanical agitation, can impact the overall cost of the service.

  • Environmental factors: Some factors, such as homes with pets, smokers, and multi-family living environments, can cause more debris in the system, which increases cleaning costs.

Labor costs

Labor is a significant factor in the overall cost of air duct cleaning. Most duct cleaning professionals charge $90 to $125 per hour. A whole-system duct cleaning takes around 2 to 4 hours with a 2-person crew. Cleaning times increase for larger homes, severe contamination, or ductwork that is difficult to access.

Additional services

Some duct cleaning companies may offer additional services like HVAC system inspections, dryer vent cleaning, or more specialized services which can add to the overall project cost. The following table details the most common expenses.

Duct cleaning company additional service cost by type
Service Average cost Description
Air duct inspection cost $80 – $180 Inspection to verify the need for duct cleaning or repairs
Dryer vent cleaning cost $80 – $250 Involves removing lint and debris buildup from the dryer vent duct to ensure proper airflow and prevent fire hazards
Rodent removal cost $150 – $600 Complete removal of rodents living in the ductwork to stop damage and avoid rodent-related health risks
Asbestos removal cost $5,000 – $30,000 Involves safely eliminating asbestos-containing materials from buildings to prevent exposure to harmful asbestos fibers
Mold removal cost $2,000 – $10,000 Cleaning and mold remediation using professional gear and equipment to ensure total containment of airborne spores

How to save money on duct cleaning

The best way to save money on duct cleaning is to properly maintain your entire HVAC system to prevent duct contamination in the first place. Follow these guidelines for an effective routine maintenance plan:

  • Clean air filters regularly rather than replacing them, as it costs less to clean them than to constantly buy new filters.

  • Repair air duct damage quickly, as cracks or punctures lead to contaminants and reduce the system's efficiency.

  • Remove obstructions in the surrounding area to ensure the air vents and registers maintain proper airflow.

  • Monitor your energy usage to promptly identify issues with your HVAC system or ductwork.

  • Avoid "cheap" duct cleaning deals or gimmicks, as these may be signs of a scam and end up costing you more overall.

How to tell if your air ducts need cleaning

If you notice any of these issues, you should have your air ducts professionally inspected and cleaned:

  • Mold or musty smell: These odors coming from the vents could be a sign of mold growth in the air ducts.

  • Visible mold or pests: Mold growth around the vents or signs of rodents/insects in the ductwork are a clear indication that you need professional duct cleaning.

  • Excessive dust: If your home accumulates dust quickly, even after regular cleaning, or if dust is visibly blowing out of the vent, it indicates dust buildup in the ductwork.

  • Clogged air filters: If your air filters are getting dirty and clogged much faster than the recommended replacement schedule, it suggests there is excess dust and debris in the ducts.

  • Increased energy bills: Dirty ducts can reduce the efficiency of your HVAC system, causing it to work harder and leading to higher energy bills.

  • Allergy symptoms: Dust, dander, and other contaminants in dirty ducts can worsen allergy and respiratory symptoms for occupants.
