Is Duct Cleaning a Waste of Money?
Some people think that duct cleaning is a waste of money, but it can be useful in some cases. To find out if you need to clean your vents, the EPA recommends:
if there’s any pests or rodents inside them;
when large amounts of mold are showing up on either side and behind each vent cover;
when dust accumulates from heavy use.
Duct cleaning, while not a necessary procedure for all households in the United States, can be beneficial to those looking to improve their home’s air quality.
