Will the residential property help you make holes for free? I have a reinforced concrete wall here, and there is no hole for air conditioning. Property evasion?

Generally, in the construction stage, the construction unit will reserve air conditioning condensate perforation on the reinforced concrete wall. If it is on the masonry wall, the construction unit will also make holes before handing over the house. You can go upstairs and downstairs to see if there are any. If not, it seems that there is no design. If some people have it, it is missing. This is the responsibility of the construction unit. You can find a property company to coordinate and solve it. If not, the property management company will not make holes for you for free!
