Great duct cleaning info.. thax

Hola cuanto vale esa aspiradora para limpiar ductos gracias

If you allow your ducts to be that filthy then don’t be surprised about the mess it makes down below. It’s much easier to clean a mess down below then in your duct system

That machine makes a big mess huh?

Better off replacing those nasty ducts.
