If the slab lap reaches 3 5 or more, there is no problem, that is, there is no safety hazard. I hope my answer can help you.
If you look at the cross-section of the wall, you can see that the load-bearing wall is wide, and vice versa, because it is only a horizontal brick or a standing brick.
It depends on the specific wall of your home, you knock on it yourself, if the sound sounds empty, then it is not a load-bearing wall, if the sound sounds muffled, it must be a load-bearing wall!
The diameter of the air conditioning hole is 5 cm, it should be no problem, who said that the exhaust hood hole is estimated to reflect the area of the wall, not to mention the air conditioning hole.
It can be demolished, the key is how many floors you have, if it's the first floor, don't demolish it.
What's not in line with that? As long as the load is calculated during the calculation, there is no problem.
