Do I need to do a duct cleaning or maybe next year?

Better see your duct using your own eyes, isn’t it?

registerFirst let us open your register. If this is clip-on type, good luck it is easy to remove. If it is an older rusty screw type ones. Then you need some patience.

duct-1

Inside looks clean, a very thin layer of dust. it will not bother me much…

duct-2

Keep going, still looks good.

debris

Hoops, some debris… but not too bad…

insects

You are not alone (flying ants) in this house…

I will just vacuum cleaning the register where I can, and wait for another year to clean my duct…
