Our Top Picks For Green Air Conditioners

If you want to stay cool and save money, you need one of our best green air conditioners.

While none of them are, yet, zero electricity waste (as Amory Lovins would prefer) they are all much more energy-efficient than most air conditioning units.

And all of them, at a bare minimum, are Energy Star compliant. 

So, if you’re looking for a greener way to stay comfortable this summer, check these awesome air conditioners out.

NEWAIR AC-14100H Portable Air Conditioner and Heater

This NEWAIR AC-14100H is an excellent buy.

But, it’s also very powerful and can cool rooms of up to 525 square feet.

It functions as an air conditioning unit, a heater, a dehumidifier and a plain fan too (though the fan is quite noisy when used like this) and it’s really well made.

1. It’s portable, so you’ll have no trouble dragging it around when you need it in another room
2. It has a heating function too which makes it very useful all year round
3. You also get a dehumidifier and fan

3. It’s a little expensive for a portable air conditioner
