Nyproduktion lägenhet med FTX ventilation systemet - kan inte söva pga ljudet
Hej!
I don't know if it's the right place to ask, but I'll give it a shot.
Problem
In November 2018 I bought a new production (nyproduktion) apartment of 33 sqm by signing a budförtecking and förhandsavtal contract. The construction of the building wasn't even started at that point of time, therefore the only material available to decide upon was the brochure and the description of the "object" written in the contract above.
The apartment was planned to be delivered two years after, in May 2020.
The budförtecking contract and the brochure, in regard to the ventilation system, only stated "FTX-system", but anything more.
The förhandsavtal contract didn't state anything on that regard.
Fast-forwarding, we reached May 2020 and I got the keys.
The only room in the apartment has two luftventiler which emit 27-32 dbs of constant noise, which doesn't allow me to sleep during the night or work during the day.
Imagine to live like there is somebody in the apartment above vacuum cleaning 24/7.
The ventilation system is for the whole building (it's basically a big fan on the roof delivering air thru big pipes to every apartment).
You can look at a diagram here: http://www.svenskventilation.se/ventilation/olika-satt-att-ventilera/ftx-varmeatervinning/
I did some researches online, and it seems to be an issue also for other people.
The day after the inflyttningdatum I opened a complain ticket with the constructor, stating that I didn't sign for this.
It's not possible for me to properly sleep and live in the apartment with this constant noise.
The apartment is placed in a very quiet neighborhood, and in the evening and in the weekends is more silent outside than inside (!).
They sent to me the ventilation guy who took some measurements (27-32 db) and they stated it's within the ljudklass C range, that it's the ljudklass they follow.
Cool, the problem is that the ljudklass has never been comunicated or agreed with me.
The FTX ventilation system could also be designed to support ljudklass B for example.
In the contract I signed, this information has not been provided.
Being a light sleeper, I would have never agreed to buy an apartment like this knowing about the ljud emitted.
I never saw an apartment that generates (!) noise before.
It's like living in a giant microwave.
Question
I'm still discussing it with the constructor, but I would like to ask: is there something else I can do?
Is there some public body who helps people with this kind of issues?
Hallåkonsument doesn't seem to cover these issues.
There has been at least another thread on the forum about this topic, but perhaps there are some updates since 2016.
Did somebody have the same issue and solve it somehow?
As I see, the constructor has concealed a known issue of the FTX-systemet (the noise) to the customer.
Tack för din hjälp!
