Sanitär & Heizung

Top.

Excellent, fast service. Within four days of reporting the problem, a cost estimate was prepared, the old oil heating system was dismantled, and a new one was installed. The staff are very competent and professional. I can recommend this company 100%.

We highly recommend HDS GmbH! We were looking for a company to maintain and repair our boiler and found exactly what we needed. The communication on the phone was exceptionally friendly and helpful, the technician who came to our home was polite and professional, and the work was done efficiently and to a high standard. We are simply delighted and completely satisfied.

David Stöcker and his team are simply excellent! A friend of mine moved to Cologne and needed on-site advice right from the start. I was there when the boss himself gave the advice: friendly, patient, and competent, and, above all, tailored directly to the needs of the property. We felt like we were regular customers. That's wonderful! Therefore: rating: highly recommended!

A highly competent heating and plumbing company. Mr. Spiegel and his colleagues were very reliable, punctual, and helpful, and did an excellent job. I can highly recommend this company. Thanks again. Best regards, Danielle Bergerhausen
