Die Firma Kältech kann ich nur empfehlen. Der Techniker kam, sah sich das Problem an und löste es in kurzer Zeit. Die Demontage der Wärmepumpe, die Fehlernehebung sowie die Reinigung des Arbeitsplatzes war sehr lobenswert. Die Instruktionen waren lehrreich und mein Fazit; top kompetente Leistung.von Herrn Mangione👏

Danke für die zuverlässige und stets ausgezeichnete Arbeit!
