I am very happy with the mobile air conditioner, except for one thing !! The membrane pump that drains the condensation water makes a terrible spring noise. (More than 60 Db) he does this about 4 times an hour. and it only works when I use the appliance as a stove. I have district heating, but because old pipes are replaced everywhere, I regularly have no heating. That's why I use it when it is needed as a heater. He does that very well. only that pump is terrible. mechanic will come to solve that problem.
