FAQ
Frequently asked questions
What size AC do I need?
Start with room size and sun exposure, then adjust for ceiling height and how quickly you want the room to recover from heat.
Is portable or window AC better?
Window units usually cool more efficiently, while portable units win when installation limits or rental rules reduce your options.
Why does the US edition mention BTU?
US shoppers usually compare cooling categories in BTU, so the shell keeps that framing visible even before deeper calculator pages exist.
