Für unseren Ersatz der Gasheizung sind wir durch Empfehlung Dritter auf die Th. Inauen AG gestossen. Bereits beim ersten Kontakt wussten wir: Hier sind wir in guten Händen. Von der gebäudespezifischen energetischen Bedarfserfassung, über die Baueingabe für die Erdsondenbohrung, Koordination mit Gemeindediensten, Terminplanung bis zur Fördermittelbeantragung und letztlich zur fertigen, effizienten und hochwertigen Anlage - da ist alles aus einer Hand. Die Teams sind äusserst kompetent, zuverlässig, lösungsorientiert, verbindlich, speditiv und freundlich. Die Inauen AG mit ihren erfahrenen Heizungsprofis und ihren langjährigen Partnerfirmen können wir nur bestens empfehlen.
