Differences in SEER Ratings

SEER ratings come in various numbers, but what does it mean when a unit has a lower SEER rating versus a higher one? These differences can significantly impact energy efficiency and running costs.

Lower SEER Ratings: What to Expect

Units with lower SEER ratings, such as 13 or 14, are akin to an old, reliable truck for a road trip. It will get you to your destination, providing the cooling power you need, but it consumes more fuel (energy in our case) to do so.

The primary advantage of such units often lies in their initial purchase price, which can be significantly lower than higher-rated counterparts. However, keep in mind that they may cost more in the long run due to higher energy consumption, especially if you use your air conditioning frequently.

Higher SEER Ratings: What to Expect

When it comes to units with higher SEER ratings, like 18 or 20, think of them as sleek, efficient hybrid cars. They can deliver the same amount of cooling as their lower-rated counterparts but use less energy to do so. This increased efficiency translates into savings on your energy bills over time. However, the initial cost of these units is typically higher.

In addition, remember that the higher the SEER rating, the more important it is to ensure that the unit is properly sized for your space to realize potential energy savings.

How Much Difference Does a Point Make?

Every point increase in a SEER rating represents a significant step up in energy efficiency. According to the U.S. Department of Energy, each point increase in a SEER rating can reduce energy consumption by approximately 10%. It’s akin to receiving a 10% discount on your energy bills for the life of the unit.

So, for example, if you upgrade from a unit with a SEER rating of 13 to one with a rating of 16, you could see a reduction of around 30% in energy consumption related to cooling. Therefore, while the initial cost of a high SEER unit may be more, the potential energy savings could offset this over time, making it an economical choice in the long run.

SEER Rating VS Cost

Understanding the relationship between SEER ratings and cost is critical when selecting an air conditioning unit. The initial purchase price, operational costs, potential savings over time, and the break-even point are all pivotal factors to consider.

Initial Purchase Price: Lower VS Higher SEER Ratings

Air conditioning units with lower SEER ratings, like 13 or 14, tend to be less expensive upfront. Think of this like purchasing an older, less fuel-efficient truck. It might be a more affordable investment at the onset, but the operational costs can add up significantly over time due to higher energy consumption.

Operational Costs: Lower VS Higher SEER Ratings

In contrast, units with higher SEER ratings, like 20 or above, are typically more expensive upfront, similar to buying a new, fuel-efficient hybrid car. These units, however, are more energy-efficient and, therefore, have lower operational costs. The savings you accrue over time due to lower energy bills can compensate for, and eventually surpass, the higher initial investment.

Cost Savings Over Time: Lower VS Higher SEER Ratings

The U.S. Department of Energy estimates that a higher SEER-rated unit can save you up to 40% on your cooling costs over time. This percentage signifies a considerable saving, especially if you live in a region where the air conditioning unit runs for extended periods. However, keep in mind that these savings are achieved over time, not immediately.

Break-Even Point: When Higher SEER Ratings Pay Off

The break-even point is when the savings in energy costs from a higher SEER-rated unit offset the extra upfront cost paid for it. Depending on various factors like the price difference between the units compared, local electricity rates, and the extent of AC use, this break-even point can take a few years to reach.

After reaching the break-even point, you continue to save money with each subsequent year of operation, making a higher SEER-rated unit an attractive long-term investment. However, if you plan to move or don’t use your AC heavily, a lower SEER unit might be the more economical choice.
