The winter is hot

The winter is known for its bitter cold, but if you get a fantastic air conditioner, the winter will be hot.

But it's always the big problem for anyone to choose one suitable air conditioner.

Yes, it's real a big problem.

There are so many brands and so many categories of A/C, duct or ductless, cooling with heat or not, portable or not......

As to me, portable air conditioner is the best choice for its convenience. I can move it to my reading room first, then to my bedroom after reading. It can stay anywhere I want it to do.
