What to do when my neighbour is manipulating atmosphere

East of my property iliesa plot measuring about 40 cents. it has a 5 storied building. 2 weeks before a big textile shop started functioning in that entire building. Their 4 or 5 Air conditioner's outer unit are blowing hot air to my side from morning till night. 2 of the AC are of high capacity may be of 10 or 15 tons which are making high whistling/blowing sound.. At present my property is having some trees { jak, mango, teak trees and cultivation like plantain, topioca etc.] and alittle away say some 100 mtrs way from the big building lies my house. Since this is rainy season problem of heat emission is not feeling that much but it is there and it will be more in after 2 or 3 months.Moreover I wish to make a new house in this garden land.Throughout I am having the noise disturbance.If they shift their AC outer units to other side or to top of their building, some relief from noice and heat problem.I have already intimated my difficultes to the shop owner through a friend of his but no favourable action yet.Is there any remedy or solution in Law for my grievance? Now Sir, please advise me sir to whom where and how to approach
