Construction by neighbour

Hi , I live in an apartment complex in Indirapuram Ghaziabad.My neighbour in the opposite side flat has installed outer unit of his split A/C very close to our main door due to which all the hot air thrown by the unit is directly entering my house if I try to keep my gate open for cross ventilation .This also creates a lot of problem if we have any guests on the gate as the entire area remains hot due this the heat produced by the A/C . This air is directly hitting the woodwork I have got done on my main gate and there is high possibility of all the work getting damaged . I have requested the flat owner to kindly shift the outer unit a bit father bust he is not agreeing to the same and has challenged me to do whatever I can . I have also given a written application to my RWA but the flat owner is not listening to them as well . Just wanted to know if there a provision in law under which I can serve him a notice to get the Outer unit shifted and take all Eagan action ? Your opinion will be of great help to me .
