Buying an AC for a Rented Flat, PG or Hostel Room

A split AC can move with you, but each move costs money: uninstallation, reinstallation, often new copper pipe to suit the new wall, and sometimes a gas top-up if refrigerant is lost. A window AC is simply removed and refitted. If you expect to move once or twice in the next few years, a window AC is usually cheaper overall.

If you will stay several years and run the AC for long hours, a split's lower running cost — 3-star inverter splits run ISEER 4.3-4.5 against 3.13-3.4 for 3-star window ACs — outweighs the moving cost.

• Budget window AC: Blue Star WFE312L 1 ton 3-star, ₹24,890
• 1.5 ton window AC: Blue Star WFE318L 3-star, ₹28,190
• Inverter window AC for long hours: Lloyd GLW18I3AGSPR 1.5 ton, ₹32,990
• Small split for a PG room: Blue Star IA309TNU 0.8 ton inverter, ₹27,990

• A split AC needs a core-cut through the wall for the copper pipe and a bracket for the outdoor unit. Get written permission, and agree who pays to seal the hole when you leave.
• A window AC needs a window or wall opening of the right size and a strong support.
• Check the socket and wiring. A 1.5-2 ton AC should have a dedicated suitably rated socket, not a shared extension.
• In a PG or hostel, ask whether your room has a sub-meter and what rate you are charged. A 1 ton window AC can use 5-7 units on a long summer night.

AC rental services charge a monthly fee that includes installation and maintenance. It is sensible for a single summer or a short posting. Over two or three summers the rental usually adds up to more than buying a budget window AC outright, so compare the total before signing.
