Do all the rooms in the LPU hostels have air conditioning?

No, not all LPU hostel rooms have built-in AC.

However, there's a good chance you'll have access to air conditioning. 

Here's why: 

1. Over half the rooms do have air conditioning facilities.
2. If your room doesn't have AC, the hostels provide coolers upon request. 
3. Additionally, each room comes with two fans to ensure air circulation.

The LPU housing department seems to prioritize student comfort by offering various cooling options to suit individual needs. If you have a strong preference for AC, you can inquire about availability during the application process.
