Understanding the 2025 HVAC Refrigerant Mandate

Starting January 1, 2025, the Environmental Protection Agency (EPA) will enforce new regulations requiring all newly manufactured residential HVAC systems to use refrigerants with a Global Warming Potential (GWP) of 700 or less. This initiative aims to reduce greenhouse gas emissions and combat climate change. Consequently, the widely used R-410A refrigerant, which has a GWP of 2,088, is being phased out in favor of more environmentally friendly alternatives like R-454B and R-32.

Implications for Austin Homeowners

1. Existing Systems Remain Operational

If your current HVAC system utilizes R-410A, there’s no immediate need for concern. You can continue to operate and maintain it, and R-410A refrigerant will still be available for servicing existing units. However, as production of R-410A systems ceases, parts may become scarcer and potentially more expensive over time.

2. New Installations Must Comply

Any new HVAC systems installed after January 1, 2025, must adhere to the new refrigerant standards. These systems will use refrigerants like R-454B or R-32, classified as A2L refrigerants—meaning they are mildly flammable but have a lower environmental impact. Due to their flammability, these systems incorporate additional safety features, such as leak detectors and automatic shut-off valves, which may contribute to higher equipment costs.

3. Anticipated Cost Increases

The transition to A2L refrigerants is expected to increase the cost of new HVAC systems by approximately 10% to 25%. This is attributed to the need for redesigned equipment and enhanced safety measures.

4. Safety Considerations

While A2L refrigerants are mildly flammable, they are deemed safe for residential use when installed correctly. Proper installation and maintenance by certified professionals are crucial to ensure safety and compliance with local building codes.

5. Planning Ahead

Homeowners considering HVAC system replacements should act soon. As of January 1, 2026, all new systems must comply with the new refrigerant standards. While some R-410A systems may still be available, inventory is shrinking and prices are rising. Replacing your system now may be your last chance to secure a lower-cost option. On the other hand, investing in a system that meets the new 2026 standards ensures long-term compliance, improved efficiency, and environmental responsibility.

6. Local Regulations in Austin

In addition to federal regulations, the City of Austin mandates that all residential properties have functioning air conditioning capable of maintaining indoor temperatures at least 15°F cooler than the outside temperature, not exceeding 85°F indoors. This local ordinance underscores the importance of having an efficient and compliant HVAC system.

Recommendations for Austin Residents
