We would like to sincerely thank Erwin Käslin for his excellent advice and support, which reinforced our decision to purchase a heat pump boiler. The two installers and the project manager, Erwin Käslin, did a perfect job and were always professional and friendly. Their expertise and dedication made the entire process very pleasant. We can definitely recommend Insta AG and are extremely satisfied with our purchase. Rolf and Esthi von Euw

Insta AG completed my heating renovation to my complete satisfaction. Since my first contact with Dominik Schmid, I received competent advice and information at all times. He was able to explain my uncertainties and questions with great expertise and in a way that I could understand. Dominik Schmid also coordinated with the other tradespeople, which worked exceptionally well. The conversion from the oil heating system to an air-water heat pump was carried out with great care by the Insta employees. The construction site was left tidy and clean that evening. It was very, very good work, and the schedule was adhered to perfectly.
