In the past, air conditioners were only rated by their Seasonal Energy Efficiency Ratio (SEER). The higher the SEER rating, the more efficient the unit. But now, there's a new rating called the Seasonal Energy Efficiency Ratio 2 (SEER2).
SEER2 ratings - what are they?
SEER2 is the new efficiency standard as of January 2023. The SEER2 rating system is the latest iteration of the U.S. Environmental Protection Agency's (EPA) program for evaluating the energy efficiency of residential appliances. Developed in response to changing market conditions and emerging technologies, the SEER2 system is designed to replace old SEER rating system and to provide a consistent and comprehensive assessment of the energy efficiency of a wide range of products.
The SEER2 rating system is designed to provide a comprehensive picture of the energy efficiency of residential buildings. It is an update to the original SEER rating system, and it takes into account a wider range of factors that can impact the energy efficiency of a building.
Changes to HVAC Minimum Efficiency Standards from 2023
In the Southwest and Southeast regions, all air conditioners sold and installed on January 1, 2023 and onwards must meet the new SEER2 efficiency standards.
How do SEER2 ratings impact energy bills?
The higher the SEER2 rating, the more efficient the unit is at cooling or heating a given space. This means that units with high SEER2 ratings will cost less to operate over their lifetime in terms of energy costs. The ratings range from 13-25 and apply to all types of air conditioners and heat pumps, including central air systems, window units, and mini-splits.
SEER2 is a measure of energy efficiency for air conditioners and heat pumps. The higher the SEER2 rating, the more efficient the unit is. In other words, a unit with a SEER2 rating of 10 will use 10% less energy than a unit with a SEER2 rating of 9.
Department of Energy Conservation states that in total, households using A/C systems and heat pumps can save $2.5-$12.2 billion on energy bills during a 30-year period following the new standards.
Not all units have the same SEER2 rating, however. It depends on many factors such as size, type of compressor technology used, and even brand name. That’s why it’s important to research your options before making a purchase decision. You can use online resources such as ENERGY STAR® or consult an HVAC professional to get additional information on individual units and their respective SEER2 ratings.
What types of units does SEER2 apply to?
The SEER2 rating will apply to all types of air conditioners, including
- Air Conditioner Condensing Units
- Heat Pumps
- Single Packaged Units
- Evaporator Coils
- Gas Furnaces
So if you're shopping for a new air conditioner, be sure to check the SEER2 rating before you make your purchase.
Why is SEER2 important?
The SEER2 rating system will apply to both new and existing homes. For existing homes, the rating system can help identify areas for improvement that could save money and energy. For new homes, the rating system provides a benchmark for comparing the energy efficiency of different designs.
Modern systems today use 25-50% less energy compared to systems 15-20 years ago
Starting January 2023 the new SEER2 rating is now mandatory for all new furnaces and air conditioners, as well as heat pumps.
If you're in the market for a new unit, it's important to understand what this rating means. The old SEER rating system was designed to compare units that used different refrigerants. The new SEER2 system will instead focus on units that use R-410A refrigerant. This is a good thing, because it will provide a more accurate comparison of energy efficiency between different types of units.
How can I improve my home's SEER rating?
The higher the SEER rating, the more energy-efficient the system. SEER2 is a modified version of SEER that considers the dehumidification capabilities of a unit. In other words, it's a more accurate measure of a unit's true energy efficiency. So, what does this mean for you? If you're in the market for a new air conditioner or heat pump, be sure to ask about the unit's SEER2 rating. It's a good way to compare apples to apples when it comes to energy efficiency. And, as always, be sure to consult our qualified HVAC experts to find the best unit for your specific needs.
