With the new year well underway, many homeowners may not realize that significant changes have taken place in the HVAC industry that may impact their air conditioning services moving forward. The Environmental Protection Agency has implemented new regulations that phase out older refrigerants in favor of more environmentally friendly options. These changes are designed to minimize greenhouse gas emissions and improve energy efficiency. But what exactly does this mean for your AC service needs in 2025?
In this blog post, the HVAC specialists at Unique Indoor Comfort explain why these changes are happening, what new refrigerants are being introduced, and how they will impact your home.
Why Did HVAC Refrigerants Change in 2025?
The refrigerant changes in 2025 stem from the EPA’s ongoing efforts to reduce the environmental impact of HVAC systems. Older refrigerants, such as R-410A, have been found to contribute to global warming due to their high Global Warming Potential (GWP).
To combat this, the EPA has mandated a transition to lower-GWP refrigerants as part of the American Innovation and Manufacturing (AIM) Act. This shift aims to help the U.S. meet its climate objectives while also improving energy efficiency in residential and commercial cooling systems.
New Refrigerants: R-454B & R-32
To replace older refrigerants like R-410A, two new alternatives have emerged as leading options: R-454B and R-32. Here’s why they are considered to be an improvement over older refrigerants:
- Lower GWP: R-454B has a GWP of about 466, which is significantly lower than R-410A’s GWP of 2,088. R-32 also has a reduced GWP, making both options more environmentally responsible.
- Increased efficiency: These new refrigerants allow HVAC systems to operate more efficiently, potentially lowering energy bills for homeowners.
- Improved performance: Systems designed for R-454B and R-32 can deliver better cooling and heating capabilities compared to older refrigerants.
- EPA compliance: As R-410A is phased out, HVAC manufacturers are designing new systems that are compatible with these lower-GWP refrigerants to ensure compliance with EPA regulations.
How Will the Change Impact Me?
Naturally, homeowners may wonder how these refrigerant changes will ultimately impact their current HVAC systems and future service requests. Here’s what you need to know:
- Existing systems can still be used: If your air conditioner relies on R-410A, you don’t need to replace it immediately. However, as R-410A is phased out, it may become more expensive and harder to find for future servicing.
- New HVAC systems will use R-454B or R-32: If you’re planning to install a new AC system in 2025 or beyond, it will likely use one of the new refrigerants. This means better efficiency and lower environmental impact.
- Check your system’s refrigerant type: If you’re unsure what type of refrigerant your HVAC system uses, check your unit’s label or consult with an HVAC professional.
- Consider upgrading for long-term savings: If your system is aging or requires frequent repairs, upgrading to a new unit with R-454B or R-32 may save you money in the long run by offering better efficiency and lower maintenance costs.
