ᐅ Cleaning of ventilation ducts in ventilation systems

Hello

I have a newly built, 5-year-old passive house equipped with a ventilation system.

Lately, I have been thinking a lot about cleaning the ducts installed inside the building structure, since these are not accessible for removing construction dust and accumulated dirt.

I have now taken some photos with an inspection camera, showing about a 1 cm (0.4 inch) layer of dust inside the exhaust duct, which is not ideal.

After much consideration, I have found a partner with whom I have solved this problem.

We offer efficient cleaning using a cleaning pig. However, before we enter the market (planned for 1.1.2019), I wanted to hear some feedback regarding new buildings with ventilation systems.

This concerns systems installed with distributors and plastic ducts.

We would like to limit our service initially to the NRW area, but here I am interested in a realistic assessment from owners of such systems.

I have one myself and want to continue breathing clean air, not dirty, dusty air...

The method we offer is truly effective and efficient.

So, let’s hear your thoughts.

Where is a screw supposed to come from here? Everything is set in concrete.

Besides, a ventilation system isn’t exactly high-tech. As if the screw would have any significant impact. We’re talking about a punctured plastic pipe that air flows through.

Between the first floor and the attic, we have a wooden ceiling.

Raw construction ceiling beams with red ventilation pipes and OSB cladding, window in the background.


My question is, how do you even locate the screw?

I guess my builder will say the same. But if I decide to have it cleaned after a few years, will the cleaning tools even be able to pass through? Right now, I can still try to have everything done under warranty.

In my opinion, the screw doesn’t belong there and should be removed!

Then we just have to wait and see the developer's feedback...

I will report on it.

A screw in the ventilation duct is a natural element and cannot be avoided in spiral-seam ducts. So don’t worry about it. The screw does not affect the system’s function or future cleaning.

Unfortunately, I wasn’t able to reach my builder today. Hopefully, I will be able to get in touch tomorrow.

Thanks, Mycraft, for your support. The screw was not included in the price. I have nothing against screws, as long as my builder shows how to clean the duct.
