After his apprenticeship in 2007 as a plumbing installer at Chapuis & Zürcher AG in Bern, he deepened his professional knowledge for another year. In 2010, Andres successfully obtained his 3rd Federal professional title as a heating specialist in building technology planning at Haustechnikplanung Abbühl in Spiez. To gain further professional experience, he also worked at Böhlen AG in Bern. In 2010, Andres joined the company at 40%. Since 2012, he has been acting as managing director.

Herr F. Morina hat für meine über 50 Jahre alten Heizkörper, die sich nur noch teilweise erwärmten, eine finanziell annehmbare Lösung vorgeschlagen: Ersatz der verschiedenartigen Ventile durch einheitliche Schwerkraftventile mit Regelung. Er hat diese zum Teil schwierige Arbeit zu meiner vollen Zufriedenheit ausgeführt mit dem Resultat, dass das Wasser in allen Heizkörpern zirkuliert und die Wohnräume wieder wohlig erwärmt sind.

Von der Planung bis zur Ausführung wurden wir fachlich sehr gut beraten. Die Arbeiten wurden präzise, sauber, exakt oder besser gesagt einfach perfekt ausgeführt. Der Zeitplan wurde immer eingehalten. Mit dem fertigen Ergebnis sind wir sehr zufrieden. Die Remo Schönenberger AG mit ihrem zuverlässigen Team kann ich nur weiterempfehlen.
