I can't say much bad about the consultation, quote, or installation, but the customer service is a disaster.
It’s rarely possible to reach the right person, and no one seems to care about complying with the utility’s guidelines. The smart meter can’t be installed (the meter location hasn’t been retrofitted) because Green Vision isn’t following the specifications.
That’s why I’m giving the service only two points.

Excellent advice and installation of the Ovum heat pump. The only drawback is that the service team isn't always easy to reach.

The collaboration with the installation team was excellent, and even difficult situations were thoroughly discussed and resolved. The installation took place within the agreed-upon timeframe and went smoothly. Inquiries regarding configuration details after commissioning were answered in writing in a very friendly and detailed manner. Looking back after 6 months of operation, I feel I made the right choice with the Lambda heat pump and the installation by Green Vision, and I would make the same decision again.

It took less than six weeks from the initial quote to completion. The Green Vision team installed the Lambda heat pump very neatly and cleanly, all at a fixed price. All the staff, including management, were highly motivated and went above and beyond. I can wholeheartedly recommend this company.

From the initial consultation to the end, a very competent team. I spent a long time looking for a company to install the Lamda heat pump. Although it is slightly more expensive, over the years it is significantly cheaper than other well-known manufacturers in terms of operating costs.
The entire Green Vision team is very friendly and quickly found a professional solution to unforeseen problems at no extra cost. I also received excellent support with the government subsidy. Hats off to them—you rarely find that kind of service. Many thanks to the Green Vision team for the new Lamda heat pump.

I've had a Lambda heat pump running since September. It all started with the fact that the advice and quotation were in a class of their own: The advice was very thorough and adapted to my old house in several stages, the quotation was detailed and easy to understand. The installation was very professional and complex in the outdoor area, the hydraulics in the basement have become a small work of art. The commissioning was thorough and most of the parameters were well set. So far, I have only adjusted the heating curve a little and Green Vision had to increase the maximum output at 0 degrees via remote maintenance, but this was done in a few hours. After half the winter now, just before Christmas, not only is the house nice and warm, but at just under 6.0 the JAZ is even significantly better than the predicted 4.6. Unfortunately, I can't award more than 5 stars....

Hello Mr. Stoll,

Thank you very much for your detailed and great 5-star rating! We are delighted that you felt so well looked after, from the consultation to the quotation to the installation and commissioning - careful planning is particularly important for an existing building.

The fact that your Lambda heat pump is already running so well after the first half winter and that you are even well above the forecast with a SPF of just under 6.0 is a great result. It's also nice to hear that the small adjustment to the maximum output was quickly carried out via remote maintenance.

Thank you very much for your trust and recommendation. If you have any questions or would like to optimize further operation (e.g. fine-tuning the heating curve), we will be happy to help you at any time.

Best regards,
Green Vision Team

We had a Lambda heat pump installed by Green Vision in mid-October 2025. Everything went smoothly, from the consultation and technical design to the installation and handover. The support in applying for subsidies was excellent, as was the energy advice. The installation was completed in 4 days, although there were a few unplanned challenges. But none of this was a problem for the highly experienced and well-coordinated team. The system has not cost a cent more than originally planned! The house is much warmer than it ever was with the gas heating. I can recommend Green Vision for the design and installation of heat pumps at any time!
