Cleaning your air ducts does not usually require any special equipment. The method you use to clean your ducts depends on what kind of system you have. A forced-air heating and cooling system with a fan unit will need to be cleaned more frequently than a system without a fan.
If your air ducts are sealed, they may only need cleaning once a year, or perhaps twice a year. If your heating or cooling system requires duct sealing, you may need to call a professional company to do the job. It is important that you understand why you need to clean your air ducts. There are three reasons why your air ducts might need to be cleaned.
One reason is that you have a leaking duct. When you have a leak in your Central Air Ducts, you must fix the problem before you can clean it. To do this, you will need to locate the leak. After you find it, you can repair the duct by sealing the leak or patching the duct. A second reason is that you have dust. If you have a dirty air duct, you may have to clean it.
A third reason is that you have mold growth in your ducts. If your air ducts are damp, then they may have mold. You can clean the mold off of the walls of the ducts using a mild bleach solution.
