How To Tell When You Need Duct Cleaning
If you see dust on your furniture or experience things like moldy odors, dirty air filters, clogged cooling coils, musty closets, smoky rooms and dirty vents, these are all signs that your ducts need cleaning.
It is also recommended that you improve your air filtration system, and the best time to take care of that is just after your air ducts have been properly cleaned.
Anyone moving into a newly constructed home, who owns a home more than five years old and/or owns a home with children or pets should have their ducts cleaned.
People with allergies should also have their ducts cleaned on a regular basis.
