Why Sizing Matters

An undersized AC runs continuously without ever cooling the room, leading to massive electricity bills and early compressor failure. An oversized AC "short cycles" (turns on and off rapidly), failing to dehumidify the air, leaving the room feeling clammy and cold.

The Inverter Advantage

Standard AC compressors run at 100% speed or 0%. Inverter compressors vary their speed to maintain temperature, running at 30-50% power most of the time. This results in 30-50% energy savings and a much quieter operation.
