König Building Services AG

Great team and fantastic atmosphere! I'm truly impressed by the way König Haustechnik operates. The employees are consistently friendly, down-to-earth, and treat you as an equal. You can immediately tell that the work environment is great; communication is straightforward, honest, and always very pleasant. It's a team where you simply feel valued and valued. Highly recommended, if only for their friendly approach!

König Haustechnik AG is one of our top Grünbeck partners, a true expert in their field and a reliable partner for sales, installation, commissioning, and service of our Grünbeck products! We look forward to continuing our excellent collaboration!

König Haustechnik is truly exceptional! We needed to replace our gas heating system. Based on the price and performance of various quotes, we chose König. The project manager (Markus Hofer) and the team's work were professional, friendly, and highly competent! The work was carried out cleanly, and any questions we had were always answered promptly. Top company, and thank you for your hard work!

We have always been very satisfied with the services (annual burner service, tank inspection, and troubleshooting) provided by König Haustechnik und Service AG. The staff are helpful, friendly, knowledgeable, and very customer-oriented. Thank you for your dedication.

König Haustechnik und Service AG – with Markus Hofer as project manager – has brilliantly upgraded and modernized our two-year-old heating system, following some challenges during the initial installation of the previous system. Now, as a family of six, we consistently enjoy a warm house and hot water for showers. Many thanks – and a big thank you to all the installers!
