Energy-Star Air Conditioning: The Most Efficient Way to Cool Your Room
Window air conditioners can be a great way to cool a room or supplement cooling in a home that has central air that can be inefficient for a smaller space. Window AC units come in many shapes, sizes, and with different BTU ratings and power consumption ranges. Before you buy a window air conditioner it is important to understand the size of the space you are cooling, installation limitations, and the overall cost to operate.
Finding the Most Efficient Window Air Conditioner For You
BTU Ratings — Whether it's a portable unit, ductless unit, or a heater, all appliances designed to cool or heat your home will have a BTU rating associated with it. Window air conditioners are no different. British Thermal Units, or BTU, is defined as the amount of energy needed to change the temperature of one pound of water by one degree Fahrenheit. While this may sound complicated, the simple explanation is that the higher the BTU rating the bigger the living space an air conditioner can cool, and generally speaking, the more energy it takes to power the unit.
EER & SEER Ratings — Another factor to look for when determining the energy efficiency of a window air conditioner is the Energy Efficiency Rating (EER) and the Seasonal Energy Efficiency Rating (SEER). The EER is calculated by taking the BTU capacity and dividing it by the wattage. The EER should usually be above 10, as the higher the rating is an indication of greater energy efficiency. When it comes to Energy Star window air conditioners, you will notice that they all have a higher EER rating than most units. The same trend will follow with SEER ratings, as AC units rated 12 or above are generally considered to be ideal in terms of energy efficiency.
Why Energy Star Ratings Matter
The EPA’s Energy Star program was created to identify the best ways that you can save energy around your home. Any appliance that has been Energy Star approved must go through a government certification process to meet stringent efficiency standards. If you see the blue Energy Star label, then you known that specific air conditioner has undergone vigorous testing and qualified for the program.
When it comes to buying a window air conditioner, you can cut your overall energy costs by going with a unit that has been reviewed and approved for the Energy Star rating. While Energy Star appliances may be slightly more expensive than their counterparts, the amount of money you will save on your energy bills will more than off-set the initial cost of the AC unit.
Cut Energy, Save Money & Stay Cool
Before you purchase a window AC unit, it is important to understand the right sized BTU unit you will need to cool the space you are concerned about. It is also important to evaluate the energy consumption needed to power the unit as this may lead to big swings in your energy bills. You will notice that many window air conditioners available on the market are now Energy Star rated. When you consider how little energy these units require, you can start to see how an Energy Star air conditioner can save you thousands of dollars every year. This is especially important if you're shopping for a window unit that can provide both warm and cold air for year-round use.
