Split ac units on my terrace wall

i am living on first floor with private terrace however on ground floor there are shops which are rented out by owners these tenants has mounted their split ac units on my terrace wall ( some are even at height above my wall, so you can see portion of them ) and constantly throwing hot air and you literally feel not standing in terrace as you are inhaling this hot air please let me know what the law if any governing such issue in Mumbai ? BMC has any say on this ?? what recourse i have ??? unfortunately society is lawless and not functional, most of the office bearers are living on higher floors and least bothered so only i have to take actions
