Can a portable air conditioner truly save energy vs. central type
My house is one level. My kids usually play in the living room that opens to the kitchen. In the daytime, I can close all bedrooms. So I plan to buy a portable air conditioner placed in the living room that is more than 400 sqft because it opens to the kitchen. I choose the portable air conditioner because it is easy to install comparing with the window type. Do you think if it will save energy vs. the central air conditioner? In other words, should I run the central air conditioner instead? I am concerned about it may take more time to cool the room by the portable air conditioner comparing with the central air conditioner. If the portable air conditioner is a good choice, can you recommend a reliable portable air conditioner?
