Review on Split system Royal Clima RCI-RF30HN Full DC EU Inverter + breather, white by Mateusz Dbkowski ᠌

The main disadvantage is crackling or crunching during operation. If all the blades are fixed in one position, then it’s normal, but if you set the automatic mode, then the air conditioner cover and the plastic “petals” inside begin to move periodically and all this is accompanied by a crackling sound that is heard in the silence of the night through the earplugs. You don't pay much attention to it during the day. The operation of the air conditioner itself cannot be called absolutely quiet either, especially when the breather is turned on, but this is a uniform hum, you do not pay attention to it. About the vile squeak that accompanies every action has already been written. It can be turned off in the application, but only until the next time the air conditioner is turned on. The device itself and its installation are a little expensive - the guys spent almost a whole day fumbling with my meter-long brick wall in the old foundation of St. Petersburg.
