Having energy efficient room air conditioners to cool your home is especially important. Not only does it save you money, but it helps save the environment by cutting down green house emissions. A unit with a higher EER when compared to the federal standard rating will usually be accepted by Energy Star, a government program, as a highly efficient model. It will then bear the programs logo. When it comes to room air conditioners, portable units are unable to be rated by Energy Star. Though there are portable models out there that are more energy efficient than others. Window and wall units are able to be rated by Energy Star and therefore, it is easier to notice an energy efficient model due to their logo. If finding an energy efficient room air conditioner is important to you, check out the list below for some of the most efficient models.
Friedrich YS09L10
This 9200 BTU window air conditioner has the 2nd highest EER rating according to the Energy Star program. The first Energy Star rated unit is nearly impossible to purchase. This model has an EER of 12. That is quite a bit higher than the federal standard. The federal standard is based off of the capacity of the unit. In this case the federal standard is 9. That makes this unit 33% more efficient than the standard window unit with this capacity. This unit comes with 3 fan and cooling speeds, reusable filter, and 4-way air direction.
Danby DVAC8010E
Danby window air conditioners are usually rather energy efficient. Not quite as much as Friedrich units, but they are rated by the Energy Star program. This particular model has 8000 BTU and a 10.5 EER. The federal standard for this capacity is 8.5, making this model 24% more efficient than the standard 8000 BTU unit.
Haier ESAD4066
At 6000 BTU, this unit has 12 EER. That is 24% higher than the federal standard of 9.7. Unfortunately the reviews of this Haier model are rather diverse.
