IKN Kältetechnik GmbH & Co. KG

Excellent! Everything went perfectly from planning to execution. The system was installed in October and has fully served its purpose. Any questions were always answered quickly and competently, and they continued to support us. 5 stars, and we wholeheartedly recommend IKN Kältetechnik.

We would use them again anytime! Thank you so much for the reliable maintenance of our air-to-water heat pump. Finally, a company that could answer all our questions. The system is now running smoothly, something the previous installer unfortunately failed to do. Not all heating systems are created equal – it's best to rely on trained HVAC/refrigeration technicians!

In my opinion, the company operates very professionally and also supported me with the grant applications. A factory defect from the system manufacturer was identified by Mr. Griese, the employee assigned to my project, using his extensive expertise, and documented for the manufacturer's claims. The consistently courteous and friendly back office staff also deserves a mention. I look forward to continued collaboration.

The technician did an excellent job. He wasn't afraid of complicated repairs. IKN has a real talent and a genuine passion for their work. The order processing and scheduling were superb. And the prices were absolutely fair. This place is a hidden gem!

I also had a disastrous experience with Rednux! Only after activating PayPal buyer protection and threatening legal action did I get my money back after 1.5 months. Stay away from Rednux! Rednux had initially told me they would be using IKN as their service provider. I then spoke a few times with the very friendly managing director, Sascha Nebel, and he agreed to Rednux's original offer. After that, everything went perfectly! Delivery, installation, and setup—everything was top-notch! The on-site team (master craftsman, journeyman, and apprentice) was very competent and absolutely customer-fri
