voll profisionel korekt (scharf wenn mann braucht) SUPPERRR Ich WURDE weiter emfellen

Heizung ausgestiegen am Freitag 22.12.23 um 14.20h (Region Zürichsee). Servicetechniker vor Ort um 15h. Fehler rasch eruiert. Ersatzteil nicht an Bord des Servicefahrzeugs, da ältere Anlage. Innerhalb von 2 Stunden von Technikerkollegen (Region Chur) organisiert und eingebaut. Bravo. Grosses Dankeschön für diesen super Service vor den Festtagen!

Es ist uns wichtig, Ihrem Projekttechniker nochmals ausdrücklich für seine Arbeit zu danken. Er hat uns kompetent und freundlich über die Möglichkeiten eines Einbruchmeldeschutzes informiert und umgehend offeriert. Die Installationsarbeiten wurden diskret, fachkundig und sehr sauber ausgeführt. Auch wurden wir sorgfältig mit dem System vertraut gemacht. Kurz: So wünscht man sich als Kunde behandelt zu werden. Wir können die Firma jederzeit weiterempfehlen.

Gute Qualität und schnelle Lieferung. Danke.

Super Service, sauber Arbeit. Efficient und zuverlässig. Fam. Darlington

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!

Ich kann nur Danke sagen. Herzliche Grüsse Ocakhan
