Global AC Guide brings three free cooling tools together: estimate room AC capacity in BTU, calculate running costs using your own electricity tariff, and find an AC type that fits your room, windows, and installation permissions. See the assumptions behind each result, then explore practical buying and troubleshooting guides. Built for renters and homeowners planning room cooling.
