  2. Easy Installation: Installing a window AC unit is relatively straightforward and can be done by the homeowner, saving on installation costs.
  3. Energy Efficiency: When used to cool individual rooms, window AC units can be more energy-efficient because you only cool the spaces you’re using.

Choosing the Right Option for You
