By type & technology
A window AC is a complete air conditioner in one box. There is no outdoor unit, no copper piping and no core-cut through the wall, which makes it cheaper to buy, cheaper to install and easy to take with you when you move — the reasons it remains the right choice for tenants, PG rooms and anyone on a budget under about ₹30,000.
The costs are noise and efficiency. The compressor sits in the box, so a window unit is audibly louder than a split, and the 3-star window ACs we compare run ISEER 3.13-3.4 against 4.3-4.5 for a 3-star inverter split. On a 1.5 ton unit run all summer, that is a difference of well over ₹2,000 a year.
The exception worth knowing about is the inverter window AC. Lloyd's GLW18I3AGSPR varies its compressor speed like a split, and if you rent and run the AC for long hours it narrows much of that gap.

Most window ACs are fixed-speed. An inverter window unit costs a few thousand more and is cheaper to run over a summer.
0.8 ton suits about 90 sq ft. A window unit sized too small will run flat out all afternoon.
Measure the window or wall opening before buying. A 1.5 ton unit is larger than a 1 ton and needs a stronger support.
