Air cooler or AC in Rajkot? Climate verdict, tonnage, season

In Rajkot, Saurashtra’s inland plateau bakes dry through May — Rajkot’s market for jumbo desert coolers is among Gujarat’s strongest, with ACs reserved for the monsoon’s sticky spells. Here is what that means for the cooler-or-AC decision.

Cooler or AC: the Rajkot verdict

Dry heat (≈ 42 °C peaks, ≈ 25% humidity) makes Rajkot one of India’s best cities for evaporative cooling. Through March to June, peaking in May, a well-sized cooler (25–30 air changes per hour) beats an AC on cost ten to one; the only caveats are water supply and the brief muggy spells when the pump should simply be switched off.

Tonnage for this climate

For Rajkot, the working rule is 1.5 tons for a 12×12 ft bedroom, 2 tons for halls, and rated capacity at 46 °C checked. Read the BEE label’s ISEER and annual kWh rather than star count alone, and in this dry heat, check rated capacity at 46 °C ambient. Guides: split ACs, BEE stars, inverter tech.
