We are thrilled with our collaboration with Suntherm AG. From the initial consultation to the commissioning of our photovoltaic system, everything was handled with absolute professionalism and on schedule. Thanks to their first-class work, we now generate sustainable electricity while simultaneously reducing our operating costs. A clear recommendation for anyone who values quality, reliability, and first-class service!
Friendly service and excellent installation of our heat pump hot water boiler. The after-sales customer service was also excellent (I called in the evening about a warranty defect, and the technician fixed the problem the next day). I highly recommend Suntherm and Mr. L. from Wohlen.
About two years ago, I had a Suntherm heat pump boiler installed in my house. Until recently, it worked perfectly, then the heat pump stopped working with an error message – thankfully, the electric heater continued to function. Suntherm replaced the faulty temperature sensor on the condenser free of charge, even though the warranty had expired, and now everything is running smoothly again. Fast, clean work and excellent customer service – thank you!
Six years ago, I had a geothermal heat pump system installed in my five-unit apartment building using Suntherm. Since I was 100% satisfied and never experienced a single problem, I installed two more heat pumps in two apartments with terraces a year ago. These incredibly quiet units even surprised my neighbors. You can't hear a thing 10 meters away from them. I highly recommend Suntherm.
I called twice at the beginning of last week and asked for an urgent callback. I'm still waiting...
Excellent service from order placement to installation. The heat pump works reliably. Highly recommended!
