How Much Does Vent Cleaning Cost And Other Facts About Vent Cleaning

Are you noticing more dust accumulation than usual? Does the air quality in your home seem to be dwindling? If so, it’s time to have your air ducts cleaned. But how much does air duct cleaning cost and how often should it be done?

Typically, vent cleaning should be performed every 3-5 years. It should be done yearly or bi-yearly if you live in a home with pets, smokers, or anyone suffering from allergies or breathing issues. Keep reading to find out how to determine the cost of air duct cleaning.

How Much Does Vent Cleaning Cost?

Depending on the size of your home, air duct cleaning can cost anywhere from $350-700. Other factors such as the degree of contamination also factor into the final cost. As well if you add in the cost of cleaning the dryer vent, it will drive up the final cost.

Here are some other factors that contribute to the cost of the air vent and duct cleaning.

  • Type of ductwork
  • Size of the air duct system
  • Accessibility
  • Number of team members needed to do the cleaning
  • Additional repairs
  • Degree of contamination 

Amount of Air Duct Units/Furnaces

If you have more than one furnace, you can expect to pay an additional $400 for each system. Homes that have additions will most likely have multiple furnace systems while older homes without additions typically only have one.

Insect and Rodent Infestation

If your system is infested with rodents or bugs, it will increase the cost. It is best to have an exterminator eliminate the problem before the duct cleaning takes place to avoid additional costs as well as health issues.

Mold and Mildew Removal

If your HVAC system has mold or mildew growth, it could increase the cost by up to $6,000. This is due to the fact that there are special chemicals and equipment required to safely and professionally remove mold and mildew, not to mention additional time.


Typically, most HVAC systems are able to be accessed via utility rooms or basements. However, if your system is difficult to reach (attic or crawlspace), it could add to the cost of the duct cleaning.

Custom Designed Ductwork

If your home has ductwork that has been custom-designed, you can expect to pay an additional 25-30%. Custom ductwork usually requires special tools or techniques to complete the job, thus adding to the final cost.

How Much Does Vent Cleaning Cost Per Vent?

Typically, each vent will cost around $35 for professional cleaning. Add up the number of vents in your home and multiply by $35 to get a rough cost. Keep in mind that the above factors also come into play for the end cost.

Following is typically how professional vent cleaning companies determine vent cleaning cost other than per vent:

  1. Flat fee plus additional vents: Some companies charge a flat rate for a set amount of vents and then charge an additional fee for vents above that amount.
  2. Trip fee plus each vent: Some will charge a flat rate for the trip and then a separate charge for each vent.
  3. Per square foot of the ductwork: Some duct cleaning companies charge per square foot of your HVAC/duct system.
