The cost of living is below average, but duct cleaning runs slightly above national averages.
Duct cleaning alone won’t raise home value, but HVAC upkeep helps protect equity.
Keeping your home's HVAC system in good working order is essential, no matter where you live. However, in Raleigh's humid climate, it's crucial not only for comfort, but also to help protect your home's contents, and even its structure. Part of the necessary maintenance involves occasional duct cleaning. Partly due to demand, air duct cleaning costs in Raleigh are slightly higher than national averages, coming in at between $328 to $617, with an average of $463.
System efficiency and the ability to deal with large temperature and humidity swings make forced-air HVAC systems commonplace in Raleigh, NC. While simple duct maintenance jobs, such as regular filter changes and keeping vents clear, are excellent as DIY tasks, duct cleaning itself requires the tools and skills of a local duct-cleaning professional to address every part of the duct system. These are the primary cost factors for duct cleaning in and around Raleigh.
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.
The cost of cleaning ductwork is $0.15 to $0.30 per square foot. So, to clean vents in a 1,500-square-foot house, expect to pay between $180 and $360. Here’s a breakdown of the average air duct cleaning costs based on the size of your home:
| Home Size (Square Feet) | Average Cost Range |
|---|---|
| 1,000 | $160–$280 |
| 1,500 | $255–$505 |
| 2,000 | $340–$675 |
| 3,000 | $505–$1,015 |
As with ductwork, the more vents you have, the more it’ll cost to clean them. On average, vents cost $35 each to clean, with most homeowners paying between $25 and $50 per vent. To get a ballpark estimate for the cost of vent cleaning, count the vents in your home and multiply that by $35.
Here’s how the number of vents affects your air duct cleaning cost:
| Number of Vents | Average Cost Range |
|---|---|
| 8 | $225–$450 |
| 12 | $340–$675 |
| 16 | $450–$900 |
| 20 | $565–$1,125 |

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.
| Type of Duct | Average Cost Range |
|---|---|
| Metal | $170–$450 |
| Flex | $395–$570 |
| Fiberglass | $225–$480 |
| Fiberboard | $225–$480 |
Most Raleigh ductwork pros charge by the hour, with duct cleaning services priced between $90 and $125 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.
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, it can result in additional labor charges.
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.
Duct cleaning is offered as a package with set labor costs, but extremely dirty jobs will cost extra. If the ducts have never been cleaned and need a lot of work to remove dust and buildup, expect additional fees.
If additional work is necessary to complete your project, other expenses may affect your total project cost. In some cases, you may also need the expertise of other specialists.
If your professional discovers excessive debris or other issues in your system, such as damaged sections, leaks, or air duct blockages, duct repairs may be necessary, which can increase your total job cost. Typical duct repair prices range from $200 to $800.
You won't need a permit for duct cleaning in Raleigh. However, if repairs are necessary, your contractor may need to get one. An HVAC permit costs between $50 and $300, depending on the scope of work, and it will be part of your ductwork repair cost invoice.
In cases where cleaning your home's HVAC ducts isn't quite enough to get things back in order, you may choose to hire additional professionals. Discovering the presence of mold, pests, or asbestos when cleaning ducts isn't unheard of. Additionally, you may consider additional HVAC services before, during, or after your duct-cleaning service.
Pest control costs: $50–$500
Mold remediation costs: $1,222–$3,750
Asbestos removal costs: $1,204–$3,254
Dryer vent cleaning costs: $103–$185
HVAC air filter replacement costs: $10–$50
Furnace cleaning costs: $70–$400
While maintaining your HVAC system is crucial in a climate like Raleigh's, cleaning your ductwork doesn't, by itself, boost the value of your home or carry a significant ROI. However, proper and ongoing HVAC maintenance in general can help protect the investment you have in your house.
Cleaning or repairing your home's ductwork when necessary is essential for comfortable living. More importantly, it also helps protect the house from humidity and mold issues that can negatively impact its value.
