Well, because when constructed space in wall (not a window) was constructed. An opening for an air conditioner for each room.

Yes, the Mistubshi is a great product. But my up front cost were minimal during construction. And I only use one air conditioner at a time. So I don't require a mega-BTW unit. Each room can be set or ON/OFF as required.

And all of my wall air conditioners were purchased used at yard sales. About $25.00 a piece. So my up front cost was low.

I still have two units that are over 30 years old and still operating. Yes, they do use more electricity then new ones. But these are used infrequently.

So my up front cost for air conditioning was about $100.00. Not $3,000 or more.

For the replacement - I now purchase new wall/window units that are more energy efficient.

Thank you for the suggestion.
