Here's a summary of the key features to consider:

EER and SEER are two measurements that gauge the efficiency of air conditioner units. EER stands for Energy Efficiency Ratio, and it's a standardized measurement that calculates an AC unit's performance at an outdoor temperature of 95°F.

The SEER rating, on the other hand, takes into account the entire season, calculating efficiency at a temperature range from 64°F to 104°F. This makes SEER a more accurate measurement, but it may not be available for all air conditioners.

To put it simply, EER is like a snapshot of an AC unit's performance in hot climates, while SEER is like a video that shows how it performs over the entire season. You can figure out the EER of any AC using a simple formula: EER = Cooling Capacity (BTU) ÷ Cooling Watts (W).

The EER and SEER ratings are not interchangeable, and there's no combined energy efficiency ratio. So, if you're shopping for a new AC unit, make sure to match the ratings when comparing different models.

Here's a quick comparison of the two:

To choose the right energy efficient window air conditioning unit, you need to consider the room size and cooling capacity. A unit that's too small will struggle to cool the space, while one that's too large will be less efficient and may not remove humidity effectively.

To determine the room's square footage, simply multiply the length by the width. If the room is odd-shaped, use a calculator to get an accurate measurement. You can also consult a handy chart that breaks down square footage to needed cooling capacity.

A good rule of thumb is to add 600 BTUs for each additional person over two people regularly using the space. If the room is in direct sunlight, add 10% more BTUs to the total capacity.

Here's a quick guide to help you determine the right cooling capacity for your room:

Keep in mind that most window air conditioners can't cool areas over 700 square feet economically, so consider a mini-split or central air conditioner if you have a larger space.

Remember, a unit that's too big will be less effective and may not remove humidity effectively. By choosing the right size and cooling capacity, you'll be able to enjoy a comfortable and energy-efficient space all summer long.
