HPS Energietechnik GmbH — Oberdorfstrasse 13, 4564 Zielebach, Switzerland

I can recommend this company with a very clear conscience. They retrofitted four apartment buildings for our housing cooperative, Berna, with air source heat pumps and photovoltaic systems. From the initial contact, planning, quotation, and implementation, it was simply PERFECT. Superb work. Motivated and innovative employees, and the boss was on the construction site almost every day, not just watching.

Poor workmanship, numerous defects. The company shows little willingness to address these issues. Extensive waiting times and multiple follow-ups are required before anything is done. Major defects are not rectified, and the company resists resolving them tooth and nail. Unfortunately, there is no professional pride and the service quality is poor. Attached are some pictures illustrating the quality of the work.

Excellent service and quality. We recently had a PV system installed by HPS Energietechnik and are very satisfied. The managing director himself was on the roof and helped out. Therefore, I don't understand the first review here on Google...🤔 It was clean, reliable, and professional work! Bravo! We'd gladly use them again 👏🤝 …
