ᐅ Contact person for centralized mechanical ventilation systems in residential buildings in Berlin?

We are still undecided between a central and decentralized mechanical ventilation system with heat recovery for our planned single-family home. Regarding decentralized mechanical ventilation, I have already had good consultation meetings with two independent companies. They concluded that for our project (a 1.5-story gable-roof house about 9x10 m (30x33 feet) with a converted attic), we will need to invest approximately 6,500 to 7,000 EUR if we want the quality we desire, including heat recovery and reasonably quiet units.

This seems to bring the cost quite close to that of a central mechanical ventilation system with heat recovery, but how can I find out more? Can anyone recommend good contacts, preferably in the Berlin area?

Thank you,

I can recommend my ventilation installer... I have shared my experiences multiple times here... but it is not a Berlin-based company... they operate nationwide...

Hello,

that would be great. Could you tell me where I can find it? I know you have a system from Wolf, but who designs, installs, and so on the Wolf system is also quite an important detail, right?

Thanks & regards,
