Both types work — but one is clearly better for most Samastipur homes. Honest comparison based on Bihar's actual extreme conditions.
Jab bhi Samastipur mein naya AC lene ki baat aati hai yeh question zaroor aata hai. Dono kaam karte hain — lekin Bihar ke specific conditions mein ek clearly better choice hai.
| Factor | Split AC | Window AC |
|---|---|---|
| Upfront cost (1.5 ton) | ₹28,000–₹45,000 | ₹22,000–₹32,000 |
| Installation cost | ₹1,200–₹1,800 | ₹600–₹1,000 |
| Electricity efficiency | Higher (esp. inverter) | Lower |
| Indoor noise | Very quiet | Moderate |

| Installation flexibility | Any wall | Needs window/hole |
| Inverter technology | Wide options | Limited |
Window ACs have their compressor and condenser in one box sitting in the window — half inside, half outside. In 44°C Samastipur heat, the outdoor part gets extremely hot, reducing heat rejection efficiency. Split ACs have the outdoor unit mounted separately in better-ventilated locations. At peak Bihar temperatures, split ACs are 15–25% more efficient than equivalent window ACs.
Window ACs have compressor, condenser fan, and evaporator all in one unit — inside your room. All mechanical noise right there. In Samastipur's smaller rooms with thin walls this is significant, especially at night. Split ACs have all noisy components outside — dramatically quieter for sleep quality.
5-star inverter split: 120–140 units/month at 10hr daily. 3-star window: 180–210 units/month. At ₹6/unit — ₹360–₹420 saved monthly, ₹1,800–₹2,100 per 5-month summer. Split AC recovers its price premium in 2–3 years through electricity savings alone.
