My CTA heat pump is still under warranty and hasn't worked properly for a single winter. Now the entire heating circuit needs to be replaced. After several attempts to contact them via email and phone (support), requesting a response, I haven't received any reply!

One star is definitely too much. Stay away from this company!!! They keep stalling with promises of callbacks and are incredibly rude on the phone!!! Thankfully, CTA has a partner company that is incredibly friendly and whose communication is fantastic. I will never use CTA again. This is my experience and my opinion, based on a bad experience.

Our CTA heat pump has been running flawlessly for years. We are very satisfied with its performance and reliability. This year's service confirmed the system's perfect condition. The CTA staff are always very friendly, helpful, and reliable. The comprehensive documentation for the heat pump is particularly noteworthy. A real highlight is the remote monitoring and control option. Thanks to the straightforward and courteous support from the CTA staff, I've also made good progress with the integration into Home Assistant.

I chose CTA AG because it's a family-run business with production facilities in Switzerland. I had an air-to-water heat pump installed and am very satisfied with the quality and services of CTA AG. I also signed a CTA Plus contract which includes repair costs, on-call service, etc. I highly recommend the company.

CTA AG is a top client. We work together regularly and are entrusted with their crane operations. We plan the transports together, and everything runs like clockwork. We are happy to recommend CTA AG as a business partner.
