Window AC vs Split AC — When to Choose Window?
Window ACs are a single-unit solution — both the compressor and the cooling unit sit in one box mounted in a window or wall. They're cheaper, easier to install, and perfect for renters or small spaces where drilling isn't an option.
| Factor | Window AC | Split AC |
|---|---|---|
| Installation Cost | ₹1,000–1,500 | ₹3,000–5,000 |
| Unit Price (1.5T) | ₹22,000–35,000 | ₹30,000–60,000 |
| Noise Level | Higher (same room) | Lower (outdoor unit) |
| Aesthetics | Blocks window | Clean, modern |
| Portability | Easy to remove | Permanent |
| Best For | Renters, small rooms | Permanent homes |

Frequently Asked Questions
Is a window AC good for rental apartments?
Yes! Window ACs are ideal for rentals. They require minimal wall work, can be removed when you move out, and cost ₹1,000–1,500 to install vs ₹3,000–5,000 for split ACs.
How much does it cost to run a 1.5 ton window AC?
A 5-star 1.5 ton window AC consumes approximately 1.2–1.4 kWh per hour. At ₹6/unit, running 8 hours daily costs about ₹1,400–1,700/month.
Can a window AC be installed without a window?
Yes — window ACs can be installed through a wall using a sleeve kit. This is common in rooms without suitable windows. A local technician can cut the required opening.
Are inverter window ACs available in India?
Inverter window ACs are rare but beginning to appear. Most window ACs in India still use fixed-speed compressors. For inverter efficiency, a split AC is the better choice.
