How did they do it? Air Duct Cleaning (Part I)
Just like dust and allergens on the surface of you home can cause irritation and allergens – fungi and debris that build up in your air ducts have the same effect. However, the EPA recommends that air ducts should only be cleaned on an ‘as needed’ basis; instead of routinely.
If you currently use a fuel burning furnace, fireplace or stove, you should have your air ducts inspected to ensure proper functioning. To do this you should have the ducts serviced before each heating season. Taking such preventative measures will help protect your home from carbon monoxide as well.
If you decide to have your air ducts cleaned, please DO NOT take this on as a DIY project. It is very important that this process is done correctly by a professional. To help you better understand the procedure, we decided to outline the process and share some preventative tips. This way you will know exactly what to expect.
How are they cleaned?
The air duct cleaning process typically entails inspecting and cleaning the following heating/cooling components: air ducts, cooling coils, grilles and diffusers, heat exchangers, heating and cooling coils, condensate drain pans, fan motors and fan housing, and the air handling unit.
The following image displays an EPA diagram of a typical home heating/cooling system. This should help you identify the parts of the unit being cleaned:
Tomorrow we will give you a little more insight on how air ducts are cleaned, outline standards behind duct cleaning, and tell you a few preventative measures to keep them clean longer. Please let us know if you have any questions!
