Vor einigen Wochen habe ich mich für den Service eines Solartechnik-Anbieters entschieden und bin unglaublich zufrieden. Die Fachkompetenz des Beraters war beeindruckend und er hat mir alle Schritte geduldig erklärt. Dank der Unterstützung hat alles schnell und unkompliziert geklappt. Es ist toll zu wissen, dass ich nun umweltfreundliche Energie nutze!

As a holistic partner for all concerns and construction projects relating to building technology, we implement high-quality and optimized solutions in accordance with the wishes and goals of our customers. From simple heating system replacements to solar systems to complex installations, we are happy to assist you. Our solutions in the areas of heating, ventilation, air conditioning and solar collectors / photovoltaics are created in close cooperation with our sister companies (planning & engineering - s3 GmbH , execution - HSH AG ) and in constant contact with the client. This enables us to accompany you from decision-making through installation to system optimization and maintenance. Our transparent approach creates systems that are not only sustainable, but also mesh seamlessly and are in harmony with the needs of the users and residents of the building.

Die Mitarbeitenden der JGE arbeiten nicht nur hochprofessionell sondern sie erklären auch für Laien verständlich was sei anbieten und tun. Auch sehr freundlich und jederzeit erreichbar. Aufgrund der Super-Arbeit haben wir JGE auch gleich die Renovation des Badezimmers in Auftrag gegeben. Alles Top und gerne wieder.
