I bought a new Viessman brand air conditioner and it only cools at 18 degrees—it does not cool at any of the other levels. It is probably faulty when it left the factory, which makes me question their quality control process. Customer service does not care at all about this product. Although I have ...
Magnificent Viessmann! I’ve always preferred German products and had great trust in the Germans. I admired their work ethic and way of life. We bought a Viessmann heat pump. We used it for 2 months last year and only until February 20 this year. Today is April 11, and our heat pump still hasn’t been...
On 12.02.2025, our Viessmann boiler with serial number 7514912401447100 displayed an F5 fault, so we called the service center at 444 9092.

For the past few years my Viessmann air conditioner, just not giving me what it's supposed to...there were holdups in getting the air conditioner's gas tank refilled because of the pandemic. When I originally contacted their service, they said they'd be right over as soon as the gas supply problem w...
The boiler I bought only 3 months ago malfunctioned. I called the service, they came the next day and looked at it. They said that the hose inside the boiler was defective.
