Thienhaus GmbH & Co. KG

I received very quick help. My heating system stopped working on a Sunday afternoon (in January – it was cold). So, I called Thienhaus the following Monday and explained my problem. After taking down all the relevant information and describing the fault, an employee came by that same morning to help me. The heating system then worked temporarily, but a replacement part had to be obtained. The defective heating module was installed and adjusted the very next morning. Everything is working again. The technician was very friendly and competent. That's how it should be. I can highly recommend Thie

Thienhaus has been working with me on various properties since the 1980s. What has remained constant, however, is their reliability, speed, expertise, and pleasant working environment. Highly recommended!

The installation of our heat pump went perfectly. Mr. Gräfe's service was also exemplary. We are very satisfied.

Despite a promised callback, we haven't received one even after several weeks! That's not how customer service should be! Every customer is welcome to read the other reviews of this company and form their own opinion! Thankfully, there are other companies in Wuppertal that actually keep their promises.

I initially called to inquire about the approximate cost of the service. The woman on the phone said they couldn't give an exact price, but I should expect to pay around €150. In the end, I received a bill for €260 for just one hour of work. That's absolutely outrageous – never again!
