​You may be wondering how you can tell if your air duct cleaning is done correctly. There are a few things to look out for when determining the quality of your service. They include:

1) Test for dust inside the registers
The first thing you should do when you are checking whether or not your air duct cleaning was done correctly is to check for dust inside the registers.

If there are no visible signs of dust in there, it may mean that the equipment used during the cleaning might not have been strong enough to take out all of the dust or that not enough time was spent on this part.

2) Look for mold growth
If you find that there is a lot of mold growing in the registers, then it means that all the dust was not cleared out.
To make sure that no mold growth occurs, it is best to have your ducts cleaned regularly.

3) Check for airflow
The third thing you should do when checking if your air duct cleaning was done correctly is check for airflow.

You can do this by placing a candle in front of an outside register and then checking if the flame flickers or it goes out.

If it doesn't go out, then that means there is enough airflow going into the room and that all components are working efficiently.

4) Check how the air smells
The next important thing to check for when checking if your air duct cleaning was done correctly is to smell the air. Suppose it smells dusty or dirty. That means that not all dust has been removed from the system and will most likely circulate throughout your home.

5) Check for moldy odors
Another thing that you should do when checking if your air duct cleaning was done correctly is to check for moldy odors.
If there aren't any, then the job was successful.

6) Look at debris collected by the dryer vent
After the cleaning process is done, check your dryer vent and see any debris collected in it. If there is, the technician might not have run their vacuum correctly, and your dryer vent will need to be cleaned again.

7) Look for residue left behind on the access panel
When checking if your air duct cleaning was done correctly, the next thing you should do is look for residue left behind on the access panel.

If there is none, then it means that your air duct cleaning is done correctly.

8) Check professional certification.

9) Check the air duct cleaning company's licensing
The next thing you should do when checking if your air duct cleaning was done correctly is to check for the company's licensing.

You should check whether or not they are registered with your state board.

10)Check the warranty
The last thing you should do when checking if your air duct cleaning was done correctly is to check for warranties.

If your technician provides a legitimate warranty, it will indicate that they were confident in their work and provided services that will last. If they don't give you a written contract, you might want to reconsider hiring them for your air duct cleaning.

Conclusion:

A clean air duct system will be one of the best investments you can make to improve your health and indoor air quality
