What Ludhiana’s climate decides
Ludhiana (Punjab) gives coolers a real but finite window — dry 41 °C heat at roughly 25% RH until the monsoon, then humid air no pad can cool. The practical answer is a cooler for the dry months and an AC sized for the humid ones (1 to 1.5 tons for a standard bedroom, 2 tons for a hall).
Sizing an AC here
For Ludhiana, the working rule is 1 to 1.5 tons for a standard bedroom, 2 tons for a hall. Read the BEE label’s ISEER and annual kWh rather than star count alone, and in this humid regime, prioritise a genuine dry mode and long gentle cycles. Guides: split ACs, BEE stars, inverter tech.
