Hi all. I'm from Richmond Hill. I do dry cleaning regularly. But I began to notice that the air duct began to work poorly. I can't understand why. Who knows?

The air duct performs important functions in the home. At least it cleans the air in the house. I would advise you to consult with the masters on this issue. I use duct cleaning in Richmond hill. Here is the website of this service https://comfortclean.com/air-duct-cleaning-richmond-hill/. Hope it helps you. I think you need to resolve this issue as soon as possible.
