Window air conditioners and two hose portables are much better.
Portable air conditioner vs window air conditioner.
Portable air conditioners are usually around 100 more expensive than window air conditioners of the same cooling capacity.
This is generally more important when considering a portable air conditioner as the ac is inside the room.
For the most part when it comes to portable ac vs window ac the window units win.
The replenishment air will come from any area of the house with an air leak making that part of the house even hotter and more humid than if you didn t have the portable running at all.
Air conditioners are usually quite noisy though you can find quiet air conditioners.
Also because portable air conditioners are generally larger and start at a higher btu h they will be more expensive than window units with a lower btu h.
