You switch on the fan. Still hot.
You turn on the AC. It cools for a while… then again the heat comes back.
If this sounds familiar, your home is not the problem — your heat control strategy is.
In many Indian homes, especially in cities like Rajkot, Ahmedabad, Mumbai, and Delhi, overheating is a common issue during summer. The real reason is simple:
Too much direct sunlight entering your home
And most people try to fix this from inside using curtains or AC, while the heat is actually entering from outside.
