Hello, I would like to know if it is feasible to open a window type air conditioner under an existing sliding window of 1.5 x 1 meter

I think that this type of opening should not be made, since an air conditioner weighs a lot and in the long run the window will suffer the weight and it may not roll or cost to roll, it is preferable to do it in another place that has nothing underneath.

Hi. You can do it since it will not affect the functionality of the window. What yes, in this zone it will not be effective since the AA go in height. This is because the cold is heavier than air and is low. On the contrary it is hot. That is why AA is high and heating is low. regards
