It is the question we hear more than any other, and the honest answer is: it depends on your home. For most households, a professional air duct cleaning every three to five years keeps dust and allergens under control.
Some homes need it more often. If you have pets that shed, someone in the family with allergies or asthma, a smoker in the house, or you have recently renovated, every two to three years is a better rhythm.
There are also clear signs you should not wait: visible dust blowing from the vents when the system starts, a musty smell when the heating or cooling kicks in, rooms that never seem to reach temperature, or dust settling on furniture a day after you clean.
