I have been thinking for weeks about our ventilation system. First about the duct routing (the decision is not yet final), and now about the placement of the unit itself. This needs to be decided by tomorrow, as we have to sign the construction plan and the timber house will soon go into production.
It was always clear that the unit would be located in the utility room. Until a few days ago, when I realized that the outlets would end up directly in the roof of the carport adjacent to the house wall, which is lower in height. We can’t really position the outlets any lower because there are other devices and connections there – the space isn’t big – no basement available. I also see the problem that the air just under the carport isn’t ideal, especially in summer when the heat rises under the slightly sloped roof toward the house wall – directly into the fresh air intake pipe.
What do you think? Would you draw fresh air from under the carport roof?
So, I considered placing the system in the attic. The family immediately objected, saying, “You don’t want to crawl up there every two weeks to change and clean the filters, do you?” Changing every two weeks is probably an exaggeration. But no, I actually don’t want to crawl up there for maintenance. By the way, there is a clear height of 1.90m (6.2 ft) under the ridge.
More worrying to me is the risk that vibrations could transfer into the ceiling or walls and cause a humming sound in the bedroom at night. Although the unit would be above the bathroom, who knows...
Does anyone have experience with systems installed in attics? Maybe even in timber houses, where the walls are not solid? Do you hear anything?
The third option is to place the unit in the laundry and storage room. Easily accessible, plenty of space, including for ducts leading outside. Until I read in a planning guide that openings should not be placed too close to neighbors or your own terrace due to noise. The exhaust air would blow directly toward the neighbor’s bedroom window, only 6 meters (20 feet) away [emoji16].
Now I am completely unsure [emoji30].
Yes, we have a planner. But they can only offer advice. We have to make the decision.
You can’t make the choice for us either, but maybe you have experience or opinions regarding these concerns?
What is the least bad or least likely problem?
- Disturbing the neighbors with noise
- Risk of a vibrating timber ceiling causing noise?
- Drawing in the stagnant air under the carport roof?
Best regards

You can also extend the duct insulated to the outside under the carport.
From the enclosed utility room, we run the extended mechanical ventilation system through the garage to the outside:

stefanc8421 Sep 2017 23:31Thanks for your advice. I had already considered that as well. Extending along the wall is less feasible for us, but theoretically, it could be done through the roof using the exhaust pipe for roof installation. Visually, it’s not very appealing – but if I understand correctly, this is less of an issue for you since it goes through the garage.
I know that several people in this forum with their own system have often chosen the position in the attic because it has advantages for several reasons (which I am not familiar with).
However, it is important that neither the system nor the outgoing pipes are located in a condensation zone. I believe the critical temperature was somewhere between 10°C and 15°C (50°F and 59°F)? (not entirely sure).
This would be relevant in your case if your attic or carport is not insulated/heated.
