For a long time, I attributed humidity and mold in the bathroom to a fault that occurred while building the house. Following a recommendation, we decided to install a HANSEN ventilation system. Within a month, both were gone. There is no more condensation on the windows, as well as no unpleasant smell of moisture. I absolutely recommend it.

The HANSEN ventilation system completely eliminated mold that was growing on the walls of our vineyard cottage. The stale air gradually disappeared as well. The installers completed the installation in a couple of hours. No additional preparation or tidying up was necessary. Now I enjoy spending time at my cottage even more!

In our office, which I share with my colleagues, we had issues with poor air quality and an increased humidity. This was especially noticeable in the colder half of the year, when we weren’t opening windows as much. After the installation of the HANSEN heat recovery ventilation system, the quality of air in the office improved. The moisture that used to accumulate on the windows and wall during the cold months disappeared after a while and did not reappear. Thanks to the HANSEN heat recovery ventilation system, we have a better quality of air in the office and less dust.
