DUSW

I learned about the company through acquaintances and, after extensive consultation, decided on DUSW. Mr. Polzin, who I found to be a truly friendly and approachable consultant, was and still is always available for questions. Registration with the network operator and everything else went smoothly. We still had the scaffolding up from the previous roof renovation, and our appointment was squeezed in, saving us the additional cost of new scaffolding. The system is up and running—what more could you ask for? Many thanks, especially to Mr. P.

This week, DUSW from Wuppertal installed a new Vaillant heat pump (latest generation). Everything went perfectly and without any problems. Despite the holiday season and a slightly reduced staff, Mr. Herber did a fantastic job. He was very friendly, worked cleanly, and even took plenty of time at the end to explain everything to us thoroughly. We are completely satisfied and can highly recommend DUSW.

A heartfelt thank you to DUSW. My heat pump is working perfectly, and I'm very satisfied. I'd also like to especially thank them for their flexibility and incredibly quick responses and solutions during the renovation. The young and highly motivated team did an outstanding job with great competence and skill!

PV Anlage läuft jetzt seit 12 Monaten und die Wärmepumpe seit 6 Monaten. Ich habe mir mit der Bewertung bewusst Zeit gelassen aber beide Produkte laufen bisher zu unserer absoluten Zufriedenheit. Ein Einstellungsproblem an der Wärmepumpenheit wurde sofort behoben. Note 1 mit Sternchen von der ersten Kontaktaufnahme, Beratung, Montage, Inbetriebnahme und Servicemitarbeiter per Telefon. Ohne Ausnahme, nett, freundlich und anscheinend auch fachlich kompetent. Kann die Firma DUSW uneingeschränkt weiterempfehlen. Auch wir haben uns natürlich mehrere Angebote eingeholt, dieses war nicht das Günstig

DUSW installed a heat pump for us. The installation was incredibly fast. The staff and installers were very nice and friendly. The installation team did a fantastic job. The system was already up and running on the second day. It's particularly worth mentioning that everything from the initial consultation and foundation work to the system installation, electrical work, all the necessary paperwork, and energy consulting was handled by a single company. The price-performance ratio is also excellent. The installation team's punctuality and customer service deserve special mention. Overall, the
