What Is Energy Efficiency Rating?June 13, 2022 12:00 am Leave your thoughts
Are you asking, "What does energy efficiency rating mean?" Maybe you need to know how you can enjoy an energy-efficient summer. If you have been a victim of a heatwave, then your AC would probably be at the top of your concerns about electricity usage. EER and SEER ratings determine the efficiency of an AC unit and the impact it has on your comfort and cost.
Energy Efficiency Rating Explained
The energy efficiency ratio is just what it suggests. It is a ratio between two quantities, the energy output and the energy input. Energy output is in the form of cooling, and energy input is the electricity consumed to provide cooling. British Thermal Units are used to measure the cooling output, while Watt hours are used to measure the electricity input.
The EER can be found most often on a label located on the side of an AC, titled "Energy Guide." When purchasing a new AC unit, be sure to reference this label.
SEER stands for Seasonal Energy Efficiency Ratio. It is similar to EER in regards to the ratio of the cooling output to the electricity input. However, unlike EER, SEER is calculated over an entire summer season. SEER can be calculated using a constant indoor temperature throughout the season. Additionally, outdoor temperatures can vary from 60 degrees Fahrenheit to 100 degrees Fahrenheit.
The EER of an AC is calculated at a fixed outdoor and indoor temp. Furthermore, the EER gives a quick snapshot of the AC’s efficiency versus a complete picture of energy savings over a long period of time. EER can be calculated using a 95 degree Fahrenheit outside temperature while the indoor temp is at 80 degrees Fahrenheit.
Importance of EER and SEER Ratings
When looking to purchase a new AC unit, design, aesthetics, the form factor, smart features, and the BTU capacity are just some of the things you will first look at when deciding. It is typical for a customer to forget completely about the EER and SEER ratings. However, they are extremely important in providing energy savings and comfort.
Since it is the last thing that salespeople often talk about, the efficiency of the AC will determine the amount of energy you will save at the end of each month. The SEER and EER will provide you with a way of comparing the differences between air conditioners of different companies. It will also inform you where you could get the most bang for your buck.
While AC units with a higher EER or SEER may cost you more initially, the energy savings will pay off in the long run for the initial price you paid.
A list of benefits and advantages of an AC unit with a high rated SEER/EER includes:
- Better cooling
- Noticeable energy savings
- Decreased carbon footprint
- Lower lifecycle cost
It is important for all homeowners to have an understanding of the efficiency ratings of the system you choose. A high SEER or EER rating would supply you with the same cooling power while keeping your electricity expenses low. A lower SEER/EER rating would deliver just the opposite in terms of costs and other issues.
