HSL-Technik: A dependable partner since 2015

A modern and innovative business that readily meets customer needs.

Since our establishment in 2015, project success and customer satisfaction have always been priorities of ours. We are a small but modern business with a wealth of experience and expertise in heating, ventilation and sanitation. The traditional values of the trade are sacred to us, which is why we provide professional and quality work, whether it is installing a stylish bathroom or an entirely new heating system.

Furthermore, we take a proactive and creative approach when it comes to providing our customers with expert advice thanks to our solid and reliable know-how. Recognizing that modern buildings have special requirements in terms of heating and, especially, ventilation, we accordingly strive to offer cutting-edge technology solutions. It goes without saying that the quality of housing and life depend on sufficient air exchange, which is not possible without dedicated ventilation in buildings with airtight windows.

Most importantly, our customers appreciate us for our all-round service: from consultation, planning and implementation to maintenance and repair.
