In today’s fast-paced world, it can be tough to keep up with all the new technology aimed at protecting the environment and saving energy. That’s where SEER and SEER2 come in, making things easier for all of us. These handy ratings help us choose the best air conditioning systems, balancing comfort with cost-effectiveness and eco-friendliness. In this blog, we’ll break down what SEER and SEER2 mean, why they matter, and how they can help you create a cooler, greener, and more budget-friendly home.
What is SEER
SEER, which stands for Seasonal Energy Efficiency Ratio, is a way to measure how efficiently your air conditioner runs. It’s calculated by taking the cooling output over a typical cooling season and dividing it by the energy used in Watt-Hours. This process uses a constant indoor temperature and outdoor temperatures that range from 60 degrees to over 100 degrees, mimicking what an entire season might look like.
A higher SEER rating means your A/C uses less electricity to keep you cool. But just like how your car’s miles per gallon (MPG) might drop in city traffic compared to the highway, your A/C’s efficiency can also vary. For example, if your car gets 28 MPG on the highway but less in the city, an air conditioner with a SEER rating of 21 indicates its best performance, which could be lower depending on the conditions. Understanding SEER helps you pick an air conditioner that balances energy use and comfort, keeping your home cool without breaking the bank.
Heat pumps are unique in the HVAC realm in that they have both SEER and Heating Seasonal Performance Factor (HSPF) ratings due to their dual heating and cooling functions. Efficiency is crucial for heat pumps, as they operate year-round and rely on electricity, a pricey energy source. Opting for a higher-efficiency heat pump can lead to quicker returns on investment compared to air conditioners, making it a wise financial choice.
SEER vs SEER2
Even though the SEER system has been around since 1992, it was found that it didn’t consider how ductwork and external static pressure affect efficiency. So, in 2023, SEER got an upgrade to SEER2. This updated version uses a new M1 blower testing procedure to provide a more accurate measure of how air conditioners perform in real-world conditions.
SEER2, or Seasonal Energy Efficiency Ratio 2, takes into account the total heat removed from the conditioned space during the annual cooling season. The new M1 testing procedure increases the systems’ external static pressure by a factor of five, making the ratings more reflective of actual installed equipment performance. Starting in January 2024, all new HVAC systems were required to come with a SEER2 rating along with the standard SEER rating.
What is a Good SEER Rating
When it comes to choosing a good SEER rating for your home, there’s no one-size-fits-all answer. The best rating depends on your personal preferences and needs. Here’s a general breakdown of the different rating levels:
- 14 or higher: A good rating that can save you money compared to older models. This is the required minimum standard in some regions.
- 17 or higher: Great for those who prioritize efficiency and want to balance cost with energy savings.
- 18 or higher: Considered very good, offering optimal efficiency and savings for those looking for excellent performance.
- 20 or higher: High-efficiency rating using the latest technologies to maximize efficiency. These units have the highest initial costs but can provide the biggest savings over time.
Remember, the right SEER rating for you depends on what you value most—whether it’s upfront cost, long-term savings, or eco-friendliness. When choosing a high-efficiency air conditioner, aim for a unit with a SEER rating of 17 or higher. Traditional central air conditioners can have SEER ratings of up to 26, and extremely efficient systems such as heat pumps and ductless mini-split systems can have a rating in the 30s or 40s. But if affordability is your main concern, a SEER rating of 14 or 15 might be more suitable.
It’s crucial to consult a certified HVAC technician when installing a new AC system to ensure compliance with DOE regulations. Starting in 2024, the U.S. Department of Energy set minimum central AC SEER ratings for different regions:
- Southeast and Southwest: Minimum SEER rating of 15
- Northern states: Minimum SEER rating of 14
Benefits of a higher SEER rating
- Environmentally Friendly: AC units with high SEER ratings are more sustainable than those with lower SEER ratings.
- Higher Energy Efficiency: A higher SEER unit has high efficiency that helps you save money
- Greater indoor comfort: Higher SEER2 units often have 2 components that reduce humidity and uneven cold/hot spots.
- Rebates and Tax Incentives: Many states and manufacturers offer rebates for installing units with a higher SEER. You can also take advantage of tax incentives.
