When it comes to our energy consumption, we all want to be more efficient. Whether it's to save on our energy bill, show kindness to our environment, or a combination of both, there are several benefits to be had.
But did you know there is more than one scale to measure your AC's efficiency?
While customers have often heard or seen the SEER rating, there is another form of measurement out there today. It's called EER, and it's important to know when to use each one.
SEER vs EER: What's the Difference?
When we talk about AC unit efficiency, we typically refer to the Seasonal Energy Efficiency Ratio, which is commonly referred to as SEER. This ratio is designed to measure the cooling power of your unit.
The formula is calculated by taking the output in British Thermal Units, or BTU's, and dividing it by the watts of energy used to do it.
Most SEER ratings are located on the rated equipment through a bright yellow tag. On this tag, you'll notice a number ranging somewhere between 8 and 30. The higher the number, the more efficient the equipment is in energy consumption.
EER, or Energy Efficiency Ratio, is an older formula used prior to SEER. Implemented in 1975, it also measures your AC unit's efficiency. However, there's a distinct difference between the two formulas.
While SEER measures seasonal efficiency ratings, EER's formula is more of a constant measurement. We see this form of measurement on smaller pieces of equipment, such as window units, but it's more of a technical calculation.
So what does this mean for you, the consumer? Simply put, SEER is great for buyers to measure the overall value of a unit's efficiency. EER is more for engineers and technicians. It can compare the efficiency of two units side-by-side, but it won't take into consideration the impact of the weather on your unit's performance.
As a consumer, SEER is going to be the easiest unit of measurement when browsing AC units. However, you'll want to keep your climate in mind when considering these numbers. If you aren't sure whether your climate is drastic enough to impact a SEER rating, ask your technician what the SEER equivalent rating is for your area.
This will help you make the best choice when shopping for new HVAC equipment.
How to Gauge Your SEER Rating
A good SEER rating for an AC unit will fall into the range of 14 and above. However, don't assume that when it comes to comparing units that a higher SEER rating is automatically better.
There are various factors to consider, including your upfront cost and your estimated energy savings. In order to make the best decision for your home and budget, allow our experts to help you compare your options.
