When summer arrives and the temperature is hot, almost everyone turns to ACs to help get them through the heat. But not everyone can afford central air and window AC units aren’t great if you want to move about in different rooms in your home. A portable air conditioner might be the best option in this case. They usually come on wheels and only need a window to vent out of to function (and some don’t even need that). Most air conditioners are rated by BTUs (British thermal units) and the higher the BTUs the more powerful the AC. Most portable ACs are somewhere between 3000 and 8000 BTUs. For the average room, 6000 BTUs is great.
