Top Qualität, angemessener Preis. Super Service von der Offerte bis zur Fertigstellung. Präzise, effiziente und saubere Arbeitsweise. Monteure mit dem Gespür für Kundschaft. Obwohl ich einer der "motzigen" Kunden bin, hatte ich NICHTS auszusetzen. Empfehlenswert für alle angebotene Arbeiten. Andy

Wenn was mit der Heizung nicht stimmt, wurde es durch euch prompt erledigt.

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👏
