Big changes are here for HVAC systems in 2025—and if you’re planning an AC upgrade in Raleigh, NC, now is the time to understand what they mean for you. Here is what you need to know about the updated SEER2 energy efficiency standards and the transition to A2L refrigerants so you can make the most informed and cost-effective decision for your home.
Understanding SEER and SEER2 Ratings
SEER, or Seasonal Energy Efficiency Ratio, measures how efficiently an air conditioner cools your home over a typical season, relative to the energy it consumes. In simple terms, the higher the SEER rating, the more energy-efficient the system. It’s similar to miles per gallon for your car—the higher the number, the less energy it takes to get the job done.
However, starting in 2023, the Department of Energy introduced SEER2, an updated standard that reflects real-world conditions more accurately. While traditional SEER testing was based on ideal lab settings, SEER2 takes into account practical factors like ductwork and external static pressure from air filters and vents. Think of it as updating the “miles per gallon” estimate to include hills, traffic, and everyday wear—giving homeowners a truer picture of what to expect.
In the Southeast, the minimum SEER2 rating for new air conditioners is 14.3. This may sound lower than previous SEER ratings, but it’s not a downgrade—it’s a more rigorous and realistic benchmark. SEER2 testing is about 4.5% more demanding than SEER, meaning a system rated at SEER2 14.3 delivers roughly the same performance as a SEER 15.0 unit under the old system. The result? Better transparency and more confidence that your AC replacement in Raleigh, NC, will perform efficiently in your actual living environment.
What Are A2L Refrigerants?
The HVAC industry is transitioning to A2L refrigerants. These refrigerants have a significantly lower Global Warming Potential (GWP) compared to legacy options like R-410A (commonly known as Freon) and are part of a broader effort to reduce greenhouse gas emissions.
Starting in 2025, all newly manufactured HVAC systems must use A2L refrigerants. These new refrigerants are designed for both improved energy efficiency and environmental responsibility.
Why This Matters for Homeowners
For homeowners, these changes mean that new HVAC systems will be more energy-efficient and environmentally friendly. While existing systems that use R-410A can still be serviced, the availability and cost of R-410A will likely change over time.
Upgrading to a system that meets SEER2 standards and uses A2L refrigerants can offer:
- Long-term energy savings
- Compliance with current and future regulations
- Reduced environmental impact
Choosing the Right System for Your Home
When planning your AC upgrade in Raleigh, NC, here are key factors to consider:
- Refrigerant Type: Choose a system that uses A2L refrigerants like R-32 or R-454B for lower environmental impact and future compliance.
- Efficiency: Look for systems with higher SEER2 ratings to maximize energy savings.
- Professional Installation: Work with A2L certified technicians who are experienced in handling these new refrigerants to ensure proper installation and safety.
Energy Efficiency Tips to Maximize Performance
- Proper Sizing: Make sure your new system is correctly sized for your home. Oversized or undersized systems can waste energy and reduce comfort.
- Regular Maintenance: Schedule seasonal maintenance to keep your unit running efficiently—this includes filter changes, coil cleaning, and refrigerant checks.
- Smart Thermostat: Upgrade to a smart thermostat to optimize cooling schedules and further reduce your energy use.
