Haustec hat im Januar 25 unsere alte Gasheizung mit einer Luft-Wasser Wärmepumpe ersetzt. Wir haben uns für eine Installierung im Innenraum (Keller) entschieden. Die Planung wurde intelligent den gegebenen Räumlichkeiten angepasst. Die Installierung wurde termingerecht und hervorragend ausgeführt. Die Monteure waren sehr freundlich, konnten sich flexibel den bestehenden Raumeigenschaften anpassen und waren immer lösungsorientiert. Auf unvorhergesehene Probleme haben sie rasch, professionell und kreativ reagiert. Die Firma Haustec, mit seinem ganzen Team, können wir nur weiterempfehlen.

Herr Gänzle kam sofort als ich ihn anrief und ist sehr kompetent. Ich bin sehr zufrieden! Danke. Gerne bald wieder. Ronald Wöber
