Best Air Conditioner Buying Guide

Why is Smart to Go Efficient?

It is essential to understand that AC units tend to consume plenty of power if you leave them all day long. That is the main reason why you should find the unit that will help you improve energy efficiency.

Apart from the idea that you will have lower monthly bills, you will not compromise the overall power, which is an important consideration.

What Is Energy Efficiency Ratio (EER)?

You should have in mind that the AC efficiency depends on the EER or energy efficiency ratio. Generally, it is the ratio between power inputs and cooling capacity.

It means that you will be able to cool down your household for an appropriate amount of time so that you can prevent paying large electrical bills.

It is vital to get the highest rating possible so that you can reduce the energy used for cooling your household. However, the ones with higher EER are more expensive, which is something you should remember.

How Do I Determine the Correct BTU Size I Need?

When it comes to power output and size for air conditioners, we are not talking about its dimensions. The measurement unit for cooling capacity includes BTUs or British Thermal Units.

The best way to determine the length of time your room can cool down is by multiplying the width and length of the room your wish to place it. Then, you should multiply that result with 25 BTU, because this particular capacity can handle one square foot.

So if your room is 15 feet wide and 15 feet long, it means that it has 225 square feet. Therefore, you should take 225 square feet and multiply it with 25 BTU, and you will get the minimum capacity that you should purchase.

What Makes an Air Conditioner Energy-Efficient?

Right Size Of Your Room – Size is important for determining whether you will be able to improve overall efficiency. If you choose the largest unit, you will cause issues to your area by making it too cold or damp. On the other hand, small units will require more time to handle the space.

Therefore, you should consider the BTU capacity calculation we’ve mentioned above to determine the exact AC unit you should get.

Programmable Settings – Another important consideration is the ability to program it ahead so that you can prevent unnecessary waste of energy.

Energy Saving Features – You should get whether the AC unit features Energy Star certification. That is an important consideration when getting the one that will prevent hefty monthly bills.

Conclusion

We have presented to you the comprehensive guide on energy-efficient air conditioners. Remember that efficiency depends on numerous factors, which is why you should adequately calculate everything before making up your mind.

At the same time, you need to follow the guide and understand various features to make a quality purchase.
