What are Energy Efficiency Ratings

You have probably come across energy efficiency ratings since using your air conditioner. The term may have sound familiar, but what does an energy-efficiency rating or EER mean? It is the term used to represent the cooling capacity of the air conditioning system.

The EER is the value used to measure the cooling power that the unit provides for a given amount of electricity. The higher the EER value, the better, and an energy-efficient air conditioner can drastically cut energy costs.

The Energy Efficiency Rating or EER is essential to consider when purchasing an air conditioner. A higher EER means the air conditioner is more energy-efficient and will cost less to operate. Be sure to compare the EER of different models before making your final decision.

Moreover, understanding the EER is important because each air conditioning system is different. It will help you compare the capabilities and efficiency of each air conditioning system, thus settling for one that suits your needs. 

However, note that the EER is not perfect for comparing systems. Other important factors such as the size of the room, the specific heat of the air, and the humidity level also affect how well an air conditioner will work. The best way to find out which system is right for you is to have a professional come to your home and assess your individual needs.

Once you understand the EER, you can start looking for an air conditioning system for your home. Be sure to compare the EER of different systems before making your final decision. This will ensure that you get the most efficient system for your needs.

Examples of Energy Efficient Ratings

Most manufacturers of air conditioners provide the EER, but if they don’t, it is easy to calculate the rate by yourself. The output is expressed in BTU or British Thermal Units, while the energy or power is expressed in watts. To calculate the EER, the cooling work is divided by the total energy used. For example, if an air conditioner has a cooling capacity of 10,000 BTUs and uses 950 watts, the EER would be 10,500 BTUs/950 watts, which equals 11.

An EER rating of 11 means that the air conditioner produces 11 BTUs of cooling for every watt of energy used. The higher the EER rating, the more efficient the air conditioner. In general, air conditioners with an EER of 9 or above are considered to be very efficient.

It’s important to note that the EER is calculated based on specific conditions, so you may not always get the same efficiency in your own home. Factors that can affect the EER of an air conditioner include the size and age of the unit, the climate, and how often the unit is used.

A small portable air conditioner with a BTU of 6,000 and runs at 400 watts has an EER of 15. At 500 watts, a unit with 6,000 BTU has an EER of 12, while at 600 watts, the EER is 10. For a unit with 6,000 BTU running at 700 watts, the EER is 8.57.

A medium-sized portable air conditioner has a BTU of 10,000 and runs at 600 watts. Its EER is 16.67, which is higher than the 12.50 EER of a unit with the same size and BTU but runs at 800 watts.

Advantages of High EER Air Conditioning System

  • Environmentally-friendly

High EER air conditioners are good for the environment because of their decreased carbon footprint. It uses less energy and emits fewer greenhouse gasses. Opting for such units that will be used daily is a simple but helpful way to support the environment. 

It is good for the environment; high EER air conditioners can also save you money on your energy bill. This is because they use less electricity to run, which means you’ll see a decrease in your overall energy usage. So if you’re looking for ways to save money and be more eco-friendly, consider investing in a high EER air conditioner.

  • Improved Cooling

Air conditioners with high EER come with great features, too. One of those features is the technology for better and improved cooling.

  • Lower Utility Bills

It takes a significant amount of power and energy to cool down or heat a room. With air conditioners with high EER, energy consumption is lesser; thus, utility bills are lower. Some units even have programmable and adjustable thermostat settings that you can maximize for more intelligent use of air conditioning systems for lower utility bills.

Air conditioners with high EER are also environment-friendly as they use up less energy. This means a lesser carbon footprint and contribution to greenhouse gas emissions. So if you want to do your part in saving the environment, choose an air conditioner with a high EER rating. You can even find units with special features that further promote energy efficiencies, such as timers and temperature sensors.

When looking for an air conditioner, always check the EER rating to ensure that you are getting a unit that is not only powerful but also energy-efficient. This way, you can enjoy the comfort of a cool or warm home without worrying about high utility bills.

  • Superior Performance

A high EER value indicates that the unit offers superior performance. Most energy-efficient air conditioners are equipped with high-speed compressors and advanced features, making them robust and durable.

While an EER rating is an excellent way to compare the energy efficiency of different models, keep in mind that the actual energy savings will vary depending on how often and how long the unit is used. Also, be sure to factor in the cost of operating and maintaining the air conditioner when choosing a model.

The initial cash outlay for any high EER air conditioners may seem more expensive, but there will be a significant saving on energy and utility costs in the long run. In addition, it means that the comfort level in your home is greatly improved without paying too much for the bills. You are also contributing something to the environment that will benefit your children for a long time.

If you have an air conditioner that is not working as efficiently as it used to, it might be time to upgrade. Replacing your old unit with a high EER air conditioner can save you money in the long run while also providing improved comfort in your home. You will see lower energy bills, but you will also be doing your part to help the environment. New, high-efficiency air conditioners use less energy and produce fewer greenhouse gases, so you can feel good about making the switch.

To get the most out of your new air conditioner, be sure to have it professionally installed. This will ensure that it works correctly and that you benefit from the higher efficiency rating.
