KÄLTEgrad! Kälte- und Klimatechnik

Kältegrad installed two air-to-air heat pumps/air conditioners for us. The consultation was thorough and pleasant. During both the planning and execution phases, they took our wishes into account, while also clearly pointing out any better approaches. A very good balance! The installation was carried out professionally. The friendly installers worked cleanly, took the time to explain the systems after commissioning, and left the site in good condition. Challenges arising from the building's condition or problems with the materials were openly discussed with the customer during the installati

We had the Kältegrad team visit us to retrofit an air conditioning system in our attic. The initial meeting with the company's manager was very positive. The quote they provided met our price expectations. A suitable installation date was agreed promptly. The two tradesmen were punctual and worked cleanly and precisely. The installation of the outdoor unit on our roof and the mounting of the indoor unit went smoothly. I give Kältegrad a well-deserved 5 stars and would place another order with them in the future.

At the end of September, we had a multi-split air conditioning system with three indoor units installed in our attic apartment by the company KÄLTEgrad, and we are very happy with the result. Mr. Bullik gave us excellent advice and answered all my (many) questions both on-site and by phone. The quotes for systems from Hisense and Daikin arrived quickly, were detailed, and were priced in the solid mid-range. I had obtained quotes from several companies. The installers arrived on time for the agreed installation date and carried out their work reliably and cleanly over almost three days. Our

We are very satisfied. Competent and friendly staff, quick installation, good explanation, and very accommodating in scheduling. The air conditioner works perfectly. Highly recommended!

We've had nothing but the best experiences with KÄLTEgrad. The craftsmen work extremely cleanly, precisely, and reliably – even under the most challenging conditions. Our project in an old building was anything but simple: leaning walls, crooked structures, and old slate cladding. Despite these challenges, the team did an excellent job and delivered a result that was absolutely impressive. A clear recommendation!
