Before You Reach for Your Wallet

Finding the best energy-efficient air conditioner can be a tall order. There are so many options to choose from, and it doesn’t help that manufacturers claim their products are the best, even if they don’t live up to expectations.

But with the right approach, you should be able to find the perfect A/C for your needs. Here are some of the things you should consider before buying an air conditioner.

The most crucial factor to consider

When you’re shopping for the best energy-efficient air conditioner, one of your top priorities should be the size. The size of an A/C determines it’s overall performance and can affect the unit’s energy consumption.

If the air conditioner is too big, it will cool the air adequately but leave it damp and clammy. On the other hand, if the A/C is too small, it will have to work overtime to cool the entire space.

As a result, you’ll end up using more energy to cool the area. For this reason, it’s essential to find the right size depending on how big your room is.

Save some bucks

A reliable air conditioner also saves energy. Some A/Cs turn off the compressor and fan once the entire room is cool to save on energy.

Some use less energy to run compared to others. Therefore, make sure you compare the options available before making the final decision.

Understand ratings and what they mean

When it comes to choosing the best energy-efficient air conditioner, you have to know what exactly to look for to determine whether or not the A/C in question saves energy.

In most cases, you’ll see two ratings; SEER and EER. The former stands for “Seasonal Energy Efficiency Rating,” and the latter stands for “Energy Efficiency Ratio.”

You should go for the highest SEER and EER rating because the higher the rating, the higher the energy savings.

Go smart

If you’re keen on creating a smart home and you have devices like Google Assistant and Alexa, it may be best to get a smart air conditioner. Such A/Cs are very adjustable, and they allow you to control your energy usage since you can fine-tune the system to your liking.

Certifications don’t lie

When you’re shopping for the best energy-efficient air conditioner, it’s also essential to keep an eye on devices with the Energy Star Certification symbol.

This certification implies that the unit has exceeded or met the higher efficiency standards compared to other models. If an air conditioner has this certification and a high SEER and EER, you won’t go wrong with it.

Understand your options

To find the best energy-efficient air conditioner, you also need to explore the available options. Some of the popular options include:

Split air conditioners

This type of A/C features two components: an exterior compressor and an internal fan. The outer part goes outside to minimize the noise and heat, and the fan circulates cold air throughout your space using ducts.

Packaged A/C systems

Packaged air conditioning systems are perfect for homes that have forced-air heating due to the availability of ductwork. These A/Cs are central air, and the installation is part of a dual heating and air conditioning system (HVAC)

Window A/Cs

Window air conditioners come in a variety of sizes and are self-contained. The best thing about this type of A/C is that you only have to install it when it’s needed. However, you have the option of mounting it and turning it on when needed.

Portable air conditioners

Portable A/Cs resemble dehumidifiers. And like the window air conditioning units, they are self-contained.

You need to vent these units to the outside, and they include a kit for that. Some models are self evaporative, but some need frequent emptying to get rid of the water.

Inverter air conditioners

An Inverter A/C is different from the traditional air conditioner that cools a room by turning on and off. This unit works at a variable speed, drawing only the energy it needs to maintain a specific temperature.

Inverter air conditioners cool more efficiently, and they use less energy. However, because the technology is relatively new, you’ll have to spend more on this air conditioning system.
