Installation is straightforward with the included window kit and exhaust hose, but keep in mind that proper ventilation is essential to avoid hot air buildup in a garage that might lack standard windows.

Energy-wise, its SEER rating is 6.2, which is average and not Energy Star certified, meaning it could use more electricity compared to high-efficiency models.
