How Much Does Air Duct Cleaning Cost in Portland, Oregon? [2025 Data]

Keeping your HVAC system’s air ducts clean can help it work efficiently against Portland’s increasing frequency of wildfire smoke and other factors that affect the area’s air quality, as well as keep the HVAC system working properly. Air duct cleaning in Portland costs $318 on average, and most homeowners pay between $261 and $375. Take a look at some of the factors that affect how much you’ll pay for air duct cleaning.

Air Duct Cleaning Cost Factors 

The cost of air duct cleaning in Portland, Oregon, is based on factors like home size, number of vents, labor costs, and more. The material your ducts are made of and how dirty they are can also contribute to the total cost. We break down the things determining the cost of air duct cleaning in Portland. 

Total Square Footage of Home

The more ductwork you have, the more you'll pay for cleaning. Some local air duct cleaners base their price on the property’s square footage since the larger your home is, the more ductwork you'll have. Ductwork itself is measured in linear feet, but since it runs through areas of your home that aren’t easily accessed, it can be difficult to determine the exact length, so your home’s square footage can provide a reasonable estimate for how much ductwork there is to clean.

The cost of cleaning ductwork in Portland is $0.12 to $0.25 per square foot. So, to clean vents in a 1,500-square-foot house, expect to pay between $180 and $375. Here’s a breakdown of the average air duct cleaning costs based on the size of your home:

Number of Vents

As with ductwork, the more vents you have, the more it’ll cost to clean them. On average, vents cost $29 each to clean, with most homeowners paying between $21 and $41 per vent. To get a ballpark estimate for the cost of vent cleaning, count the vents in your home and multiply that by $29.

Don’t want to count vents? A good rule of thumb is that there is one vent per 100 to 150 square feet of living space, so you can estimate the number of vents using your home’s total square footage.

Here’s how the number of vents affects your air duct cleaning cost:

Type of Ductwork

If you have flex ducts, expect to pay toward the upper end of the range. Unlike metal ducts, flex ducts require special cleaning equipment, so you’ll pay more to clean them. Rigid metal ducts are easy to clean with a vacuum, air hose, or power brush, so they cost less to clean.

Fiberglass and fiberboard ductwork require careful cleaning with specialty equipment to minimize the risk of dislodging particulates from the material, which can then enter the HVAC system and pose health risks. Cleaning these types of ductwork will cost more than cleaning metal ducts but less than cleaning flex ductwork. 

Labor Cost

Most ductwork pros charge by the hour, with duct cleaning services priced between $74 and $103 per hour. Depending on the size of your home, the type of ductwork you have, and how accessible the ducts are, most cleaning jobs require three to eight hours of labor.

Many pros who offer air duct cleaning also repair damaged ducts, so if any of your ductwork needs to be replaced or repaired, labor costs will increase depending on the extent of the work.

Accessibility

If you ensure that vents are easy to reach with vacuuming equipment, accessibility shouldn’t be a problem. But some ductwork designs make accessing them difficult, especially if you don’t have floor vents. If air duct technicians have to work harder or take additional steps to reach your vents or other parts of the ductwork, it can result in additional labor charges.

Inspections

Some vent problems, like noticeable mold or nests, don’t require an inspection before cleaning. However, if you aren’t sure about the state of your vents, consider arranging a professional inspection. These inspections are often bundled together as part of an HVAC inspection, which costs an average of $300 but can fall under $100 for simple systems.

Level of Cleanliness or Contamination

Duct cleaning is offered as a package with set labor costs, but extremely dirty jobs with blocked ducts will cost extra. If the ducts have never been cleaned and need a lot of work to remove dust and buildup, expect additional fees.

Large amounts of buildup can damage your ducts, so you may also need to budget for the cost of duct repair if the duct pro discovers damage. Residue from cigarette smoke can be difficult to remove, so if there’s a smoker in your household, you may pay extra to clean your ducts.

Air Duct Cleaning Pro Costs

Labor costs for an air duct cleaning pro in Portland, Oregon, will make up almost all of your costs for this service, since there aren’t material costs involved. While you can do routine HVAC system cleaning and maintenance yourself, it’s best to hire a pro for duct cleaning, since they have the right equipment and expertise to thoroughly clean your ducts without damaging them.

An experienced pro can also spot damage or potential problems that a homeowner might overlook, and recommend whether you need air duct repair or cleaning. Catching problems early can save you from expensive HVAC repair costs later on. 

Does Air Duct Cleaning Increase Home Value?

Air duct cleaning won’t directly affect your home’s value, and is a relatively low-cost investment to make in your home’s HVAC system. Cleaning your air ducts regularly can extend the life of your HVAC system, keep it running more efficiently, and improve the air quality in your home.

A well-maintained HVAC system that’s had regular cleanings and inspections can help you sell your home—potential buyers appreciate knowing they won’t need to pay for expensive HVAC repairs or replacement anytime soon.
