How Much Does Air Duct Cleaning Cost in the Seattle Area?

When it comes to maintaining a clean and healthy home, air duct cleaning is often an overlooked but essential service. Clean air ducts ensure that the air circulating in your home is free from dust, allergens, and other contaminants, which can significantly impact indoor air quality. But how much does air duct cleaning with Star Ducts cost? Let’s break it down.

Factors Influencing Our Air Duct Cleaning Costs

Several factors can affect the cost of air duct cleaning, including:

1. Size of Your Home: Larger homes with more ductwork will generally cost more to clean than smaller homes.
2. Number of Air Returns: The number of air returns in your HVAC system can influence the price. More returns mean more work and time required.
3. Accessibility: If your ductwork is difficult to access, it might increase labor costs.
4. Level of Contamination: Heavily contaminated ducts that require more thorough cleaning will cost more.
5. Additional Services: Services such as cleaning the furnace unit or dryer vent cleaning can add to the overall cost.

Your Air Duct Cleaning Cost with Star Ducts

On average, our price for air duct cleaning ranges from **$550 to $720** for a standard-sized home up to 3000 sq. ft. This price can vary based on the factors mentioned above. Here’s a more detailed breakdown:

– Small homes or apartments up to 2500 sq. ft.: $595
– Average-sized homes up to 3500 sq. ft.: $840
– Large homes up to 4000 sq. ft.: $960
– Very large homes or commercial properties: $1200 and up

Cost Breakdown

– Inspection Fee: Some companies charge an inspection fee, which typically ranges from $50 to $100. This fee might be waived if you proceed with the cleaning. We do not charge customers for a price assessment at their home in the Seattle area.
– Per Vent Cost: Some companies charge per vent, with costs ranging from $25 to $50 per vent. We don’t.

Additional Costs

– Sanitization: Applying a sanitizer to kill bacteria and other microorganisms can cost an additional $50 to $150. We offer this service for free to our customers.
– Furnace Unit Cleaning: Cleaning the furnace unit itself (furnace, air handler, etc.) can add $150 to $450.

DIY vs. Professional Cleaning

While some homeowners may consider DIY air duct cleaning, it is generally not recommended due to the complexity of the job and the specialized equipment required. As professional air duct cleaners, we use high-powered vacuums, brushes, and other tools to ensure a thorough cleaning. We also have the expertise to identify and address any issues that may arise during the cleaning process.

Tips for Choosing an Air Duct Cleaning Service

1. Research and Reviews: Look for companies with good reviews and a solid reputation. Star Ducts has more than 450 five-star reviews.
2. Certifications: Ensure that the company you employ is legally registered, holds all necessary insurances, has a bond, and its employees undergo background checks. You can find all our certificates at the bottom of our homepage at [Star Ducts](
3. Transparent Pricing: Choose a company that provides a clear and detailed quote.
4. Experience: Opt for a company with experience in air duct cleaning and HVAC maintenance.

Is Air Duct Cleaning Worth the Cost?

Investing in air duct cleaning can be beneficial, especially if you have allergies, pets, or have recently completed a home renovation. Clean air ducts can improve indoor air quality, enhance HVAC efficiency, and potentially reduce energy costs.

Beware of Low Prices

We advise customers not to be impressed by low prices over the phone because this indicates several things:

1. Bait and Switch: The company only intends to put their foot in your door and raise prices once they are in your home.
2. Cutting Corners: They don’t really intend to perform a thorough cleaning and will cut a lot of corners.
3. Rogue Companies: These are rogue companies that hire untrained temporary workers and pay them to come to you with a vacuum cleaner. You can do this too!


The cost of air duct cleaning can vary widely based on several factors, but understanding these can help you make an informed decision. With Star Ducts, on average, you can expect to pay between $550 and $1200 for a professional cleaning. By choosing Star Ducts as your provider and understanding what is included in our price quote, you can ensure that your home’s air ducts are clean and contributing to a healthier living environment.
