What Mysuru’s climate decides
Mysuru enjoys one of India’s lighter cooling loads: peaks around 34 °C (45% RH typical), season March to May, mild year-round, and evenings that cool off. Many homes manage with fans and a personal or tower cooler; where an AC is bought, a small inverter (0.8 to 1 ton for a bedroom — an inverter sized small runs best here) runs gently and cheaply.
Sizing an AC here
In Mysuru, start from 0.8 to 1 ton for a bedroom — an inverter sized small runs best here, then correct for roof exposure and glazing. Compare ISEER values across models of the same label year (how), insist on inverter technology (why), and book the pre-summer service in February (maintenance).
