Most Energy Efficient Window Air Conditioners

Selecting an energy efficient window air conditioner is a just a smart wise decision, period.

Window air conditioners that claim to be energy efficient usually have three key concepts in common.  

First, they are a wise financially investment. Meaning you can run them without having to continually worry about your energy bills. Keeping money in your bank account should definitely keep you aware of how hard you push your air conditioning units, but the energy efficient window air conditioners can save you a pretty penny over non-efficient ones. 

Another positive aspect of energy efficient AC’s is that they assist with reducing our carbon footprint. If only generations before us had kept Mother Earth in their thoughts prior to scientists warning us of the ozone layer having issues. 

And third, but certainly not least, the main reason why you’re on the search for an air conditioner to begin with, the ability to cool your house significantly! 

However, with so many of these appliances on the market, it’s often harder to know which one is best for our homes. For this reason, here, we review seven of the most energy-efficient window AC’s.

Why Look to Those More Energy Efficient Window AC’s?

Undeniably, for most people, when running a window air conditioner, it’s the one product they use repeatedly. Thus, most are used throughout the entire year, regardless of the season.

Therefore, because of such continued use, factors such as energy used, running costs, and, indeed, performance, are often significant factors when purchasing these units.

This means the most energy-efficient window AC unit chosen should claim to offer such benefits as:

  • Reduced energy bills
  • Providing smarter cooling performance
  • Improving your carbon footprint
  • Boasting a better build and quality
  • Offering additional SMART features as standard

Cooling Power Explained

Cooling power is measured in units, that is BTUs. British Thermal Units calculate how much the unit itself can cool the air around it in the space of an hour.

However, when finding the best BTU figure for your needs, bigger isn’t always necessarily better here.

So, the best way to get this right is by selecting your room size and matching it to the BTU rating that is suggested for cooling that specific space.

Energy Efficiency Ratio (EER) Explained

Overall, the higher the value of the EER on an AC, the more efficient the unit will function.

Calculating the ratio of cooling capacity to power input, the EER will generally depend on the unit in question regarding size and cooling power.

Experts claim that the best window AC units that perform the most efficiently have an EER of 12 or above.

Other Ways You Can Help Reduce Your Indoor Temperature

As well as keeping the temperature of your room consistent and comfortable, and using less power in the process, there are a few things you can do besides:

  • Increasing the air circulation by use of an additional portable fans
  • Switching on fans attached to the ceiling to improve your ventilation
  • Consider using highly efficient blacking shades and curtains
  • Try to avoid using appliances that are high in heat during the warmest times of the day, such as ovens and stoves
