HSH AG has many years of experience in the assembly, dismantling and maintenance of heating systems of all sizes. Additionally, we have a large expertise in the fields of ventilation and climate control. Heating Systems Our strength is a comprehensive and holistic approach. From advice to planning and installation to maintenance & service, you get everything from a single source. That makes us an ideal partner for a heating system replacement. Through our interdisciplinary strengths and our integral approach, interfaces are optimized and value is created through cost and energy-optimized solutions. Ventilation Whether at home, in the office or in the workshop - fresh air is essential for wellbeing. The simplest system for supplying fresh air is opening windows, but this is not always a viable solution. However, trapped rooms, noise or pollution in the outdoor area and rooms with intensive use require mechanical ventilation. With our specialist knowledge, we will advise you competently and find a suitable ventilation system for your individual needs, which increases comfort and enables energy savings. Climate Control and Cooling We offer our customers comprehensive services for everything concerning air conditioning and cooling, from planning to installation and service. Thanks to the energy-efficient design of the systems, we ensure cost-conscious and environmentally friendly operation of our refrigeration systems.

Haustec hat im Januar 25 unsere alte Gasheizung mit einer Luft-Wasser Wärmepumpe ersetzt. Wir haben uns für eine Installierung im Innenraum (Keller) entschieden. Die Planung wurde intelligent den gegebenen Räumlichkeiten angepasst. Die Installierung wurde termingerecht und hervorragend ausgeführt. Die Monteure waren sehr freundlich, konnten sich flexibel den bestehenden Raumeigenschaften anpassen und waren immer lösungsorientiert. Auf unvorhergesehene Probleme haben sie rasch, professionell und kreativ reagiert. Die Firma Haustec, mit seinem ganzen Team, können wir nur weiterempfehlen.

Rapide et professionnelle, au top !

Mit der neuen Wärmepumpenanlage sind wir sehr zufrieden. Innert weniger als eine Woche wurde die alte Heizung demontiert und die neue montiert und in Betrieb genommen. Danke für die gute Arbeit!

Die Ansprechpersonen der Hürstwald-Garage beraten und betreuen mich seit mehr als 10 Jahren jederzeit, freundlich, kompetent und zuverlässig. Die fachmännische Beratung schätze ich sehr und möchte ich nicht missen.
