The cooling of our house did not work. I indicated via DEVO that I was not sure whether there was a fault in the delivery set or in the installation in the house.

A DEVO employee indicated that he could come by. It turned out that a valve in the house was not working properly. The employee indicated that with a few soft taps on the valve everything had to work. He was then able to release the valve.

It is nice that we look beyond DEVO strictly!
