How Long Does It Take to Clean Air Ducts on Average?


Are you thinking about having your air ducts cleaned?

There are several benefits you’ll get from a clean air duct service. But before you hire an air duct cleaning service to do the job, you’ll probably want to know one thing: how long does it take to clean air ducts?

Fortunately, you’ve come to the right place. Read on to learn more about your air ducts and the steps you’ll need to take before hiring a professional.

Understanding Air Duct Cleaning

Cleaning air ducts is the process of removing contaminants from HVAC systems. These systems play a vital role in regulating indoor temperature and home air quality.

Over time, dust, pet dander, pollen, mold, and other particles can accumulate within the air ducts. This not only reduces the efficiency of the HVAC system.

It can also lead to health issues for occupants. Particularly those with allergies or respiratory conditions.

When experts do air duct cleaning in Michigan or anywhere else, they use special tools to clean out the gunk inside. The process typically includes the following steps:


Before starting the cleaning process, a professional technician inspects the HVAC system. They will assess the extent of contamination. They will also identify any areas that might need special attention.


The technician takes precautions to protect the surrounding areas from dust and debris. This may involve covering furniture, floors, and other belongings.

Loosening Contaminants

The technician will dislodge the accumulated debris and contaminants from the walls of the ducts. They will use specialized tools like brushes, air whips, and compressed air


Powerful vacuum equipment is used to extract the dislodged debris from the ductwork. This helps ensure that the contaminants are effectively removed from the system.

Cleaning Components

They also clean the parts where the air comes out. Besides the ducts themselves, other components like registers, grilles, and the HVAC unit’s blower fan are also cleaned.

Disinfection and Sanitization

Depending on the situation, the technician may apply a disinfectant or sanitizer. This will help prevent the growth of mold and bacteria in the cleaned system.

Final Inspection

After completing the cleaning process, a final inspection is carried out. This is to ensure that all areas have been properly cleaned and that the system is functioning well.

Factors Influencing Cleaning Time

The duration of an air duct cleaning session can vary significantly. This can depend on several factors:

Size of the System

The size and complexity of the HVAC system impact the time required for cleaning. Larger systems with more ductwork, vents, and components will take longer to clean thoroughly.

Extent of Contamination

If the air ducts are heavily contaminated with dust, debris, or mold, the cleaning process will take longer. This is because more effort is needed to remove these contaminants.

Accessibility of Ducts

Some air ducts may be difficult to access, especially in older buildings or those with intricate ductwork layouts. In such cases, you may need extra time to ensure that all areas are properly cleaned.

Level of Professionalism

The experience and expertise of the cleaning technicians play a role in determining how the cleaning process is carried out. Experienced professionals are likely to work more quickly and effectively.

Equipment and Techniques

The type of equipment and cleaning techniques used can affect the cleaning time. Modern and powerful equipment can hurry the process, but more thorough cleaning may also need more time.

Extra Services

Extra services such as mold remediation, duct repairs, or sanitization may be needed. These can extend the overall cleaning time.

Property Conditions

The state of the property itself can influence the cleaning time. For instance, there are properties with excessive clutter or obstacles near the vents. This might need extra time to prepare and execute the cleaning safely.

Average Timeframes

On average, a standard residential air duct cleaning session can take anywhere from 3 to 5 hours. This timeframe includes the inspection, preparation, cleaning, and final inspection stages. But, this is a rough estimate, and the actual time required can vary.

For larger homes with more extensive HVAC systems, the cleaning process might take longer. This can range from 5 to 8 hours or more.

Commercial properties, with their intricate ductwork networks and larger spaces, can take even longer. It can sometimes span an entire workday or more.

It’s worth noting that some companies might promise faster cleaning times. But, it’s crucial not to compromise thoroughness for speed. A rushed cleaning process could leave contaminants behind, negating the benefits of cleaning in the first place.

Benefits of Thorough Air Duct Cleaning

Even though the time can change, cleaning air ducts is a smart move. Here’s why:

Improved Air Quality

Removing contaminants from the air ducts helps improve indoor air quality. This makes the living environment healthier for occupants.

Enhanced HVAC Efficiency

Clean ducts allow the HVAC system to operate more efficiently. This reduces energy consumption and lowers utility bills.

Allergen Reduction

Thorough cleaning reduces the presence of allergens such as dust, pollen, and pet dander. This can provide relief for individuals with allergies.

Mold Prevention

Cleaning and disinfecting the system can prevent the growth of mold. This can have adverse effects on both home air quality and health.

Extended System Lifespan

Proper maintenance, including regular air duct cleaning, can extend the lifespan of the HVAC system. This is by reducing wear and tear caused by clogged ducts.

Cost Savings

When your heaters and coolers work well, they last longer. That’s less money spent on repairs.
