Can a 1-ton AC cool two rooms?

No — a split AC's indoor unit is built to serve the one room it's installed in, not to push cooling through a doorway into a second space. Even if the combined area seems close to what 1 Ton could handle, the airflow simply doesn't reach a separate room effectively.

This comes up most with open studio layouts or rooms connected by a wide doorway, where it feels like "one AC, one space" — but a closed or partially-closed second room genuinely won't cool properly off a single indoor unit designed for the first room. If you need two rooms cooled, that means either two separate AC units, or a ducted/cassette system designed specifically to distribute air to multiple zones — worth a real conversation with a dealer if that's your situation.
