Common Errors Contractors & Homeowner’s Make in Duct Cleaning


When it comes to duct cleaning, you want to be sure that the job is done right. That’s why it’s important to hire a qualified and experienced contractor. Unfortunately, some companies out there will employ inexperienced or unqualified workers to save money. This can lead to several problems, including poor air quality and damage to your ductwork.

In this article, we will discuss some of the most common mistakes that homeowners and inexperienced or unqualified contractors make when cleaning ductwork:

Common Mistakes of Contractors When Cleaning Air Conditioning Duct

1. They Don’t Use the Proper Equipment

In order to properly clean ductwork, you need to use specialized equipment. This includes a powerful vacuum, brushes, and other tools. If the contractor you’ve hired uses old or inadequate equipment, the job quality will suffer.

2. They Don’t Follow the Right Procedures

Certain procedures need to be followed when cleaning ductwork. If the contractor you’ve hired isn’t following these procedures, you could be at risk. Here’s what you need to know.

First, the contractor should inspect your ductwork to identify any areas that need to be cleaned. They should then use a high-powered vacuum to remove any dirt, dust, and debris from the ducts.

Next, the contractor should use a rotating brush to scrub the inside of the ducts. This will help loosen any stubborn dirt and debris clinging to the duct walls.

Finally, the contractor should use a powerful disinfectant to clean the inside of the ducts. This will kill any bacteria or viruses that may be present and help prevent mold and mildew growth.

By following these steps, you can be sure that your ductwork is clean and safe for your family.

3. They Don’t Clean All of the Ductwork

One of the most common mistakes that inexperienced contractors make is failing to clean all of the ductwork. This can lead to poor air quality and a build-up of dirt and debris.

4. They Don’t Seal the Ductwork

Once the ductwork has been cleaned, it’s important to seal it. This helps to prevent dirt and debris from getting inside. As a result, it helps to improve the efficiency of your HVAC system. Unfortunately, some contractors fail to seal the ductwork, which can lead to problems down the road.

Common Mistakes of Homeowners When Hiring Duct Cleaning Contractor

While there are common contractor mistakes when cleaning air conditioning ducts, there are also mistakes that homeowners make that can be prevented when hiring duct cleaning contractors. Here are some of them.

1. Not Verifying That the Contractor Is Properly Licensed and Insured

Most people don’t realize that there are actually different licenses that a contractor can have. For example, a specialty contractor license allows the contractor to work on specific projects.

2. Failing to Have a Written Agreement

A written agreement should outline the scope of work to be performed and other essential details, such as who will be responsible for the project’s cost. Without a written agreement, you may find yourself in a situation where the duct cleaning company you hired does not perform the work as agreed, or worse, damages your ductwork.

3. Paying the Full Amount Upfront

It is always best to pay after the work is completed and you have had a chance to inspect it. This way, if there are any problems, you can get your money back. If you are satisfied with the work, you can pay in full.


It is important to be aware of the common errors contractors and homeowners make when cleaning ducts. These errors can lead to poor indoor air quality and a decrease in the efficiency of your HVAC system. By following the proper procedures and using the right equipment, you can avoid these mistakes and ensure that your ducts are clean and your indoor air quality is excellent.
