2025 HVAC Refrigerant Change: What Homeowners Need to Know

As 2025 approaches, a significant change is coming for heating, ventilation, and air conditioning (HVAC) systems. The 2025 refrigerant transition refers to new regulations that require more environmentally friendly refrigerants in these systems. Whether you currently have an HVAC system or are considering installing one, this update could impact you. Here, we’ll explore what’s changing, why it matters, and how it may affect your home.

What’s Changing with HVAC Refrigerants?

In 2020, the American Innovation and Manufacturing (AIM) Act was passed to phase down certain types of chemicals known as hydrofluorocarbons (HFCs). HFCs are widely used in various products, such as refrigerants in HVAC systems, and play a role in contributing to global warming. To reduce this impact, the AIM Act sets out a 15-year plan to gradually reduce the use of these chemicals across the United States.

In line with this, the Environmental Protection Agency (EPA) has introduced a new rule that will take effect in 2025. This rule limits the “global warming potential” (GWP) of refrigerants used in new air conditioning systems to 750 or less. Since the current popular refrigerant, R-410A has a GWP of 2,088, it will no longer be allowed in new systems starting in 2025. Instead, manufacturers will start using newer, low-GWP refrigerants.

What is Global Warming Potential (GWP)?

To understand why refrigerant changes are happening, let’s look at Global Warming Potential or GWP. GWP measures how much heat a greenhouse gas traps in the atmosphere over time compared to carbon dioxide (CO₂). The higher the GWP, the more it contributes to global warming.

Here’s an example: R-410A, the refrigerant currently used in most HVAC systems, has a GWP of 2,088. This means it traps 2,088 times more heat than CO₂. Starting in 2025, the EPA’s new rule limits the GWP of refrigerants in new HVAC systems to 750 or less, ensuring a lower impact on the environment.

What Refrigerants Will Be Used in the Future?

Several low-GWP refrigerants are likely to replace R-410A in new HVAC systems. The two most common options are R-32 and R-454B. 

Here’s a quick overview of each:

R-32:

• GWP of about 675, making it well within the new 750 limit.
• Already used in many parts of the world and becoming more common in the U.S.
• Known for being energy-efficient and effective for cooling.

R-454B:

• GWP of around 466, which is even lower than R-32.
• A newer option that meets the EPA’s requirements.
• Also performs well for cooling and is considered safe for use.

Both of these refrigerants offer effective cooling with a much smaller environmental footprint compared to R-410A. Manufacturers are expected to start using these in new equipment by 2025.

Why Are These Changes Happening?

Reducing greenhouse gas emissions is essential to fighting climate change. HFCs, while effective for cooling, are particularly potent greenhouse gases, meaning they have a strong impact on global warming. By setting limits on GWP in refrigerants, the AIM Act and EPA aim to reduce the environmental impact of cooling systems over time.

The transition away from high-GWP refrigerants is not unique to HVAC systems. Similar shifts have occurred in other industries. If you’ve bought a new refrigerator or a car since 2013, it’s likely equipped with a low-GWP refrigerant. Now, it’s HVAC’s turn to make this eco-friendly shift.

Do I Need to Replace My HVAC System?

The good news is that the 2025 refrigerant change doesn’t require you to replace your current HVAC system if it uses R-410A. This update only applies to new systems manufactured after 2025, so you can keep using your existing system until it naturally reaches the end of its lifespan. When it’s time to replace your unit, the new system will likely use an updated, eco-friendly refrigerant. 

For now, homeowners with R-410A systems can be assured that their current setup remains compliant. This change mainly affects future equipment, allowing a gradual shift to the new standards without any immediate action required.

Will the New HVAC Refrigerant Be More Expensive?

A common question about the 2025 refrigerant change is whether it will lead to added costs. New HVAC systems using eco-friendly refrigerants may have a slightly higher upfront cost due to updated technology and compliance with environmental standards. 

However, these systems are typically more energy-efficient, which can help lower your monthly energy bills and offset those initial costs over time. If you’re keeping your current system for now, just be aware that as R-410A becomes less common, maintenance and repair costs could gradually increase as parts and refrigerants become more limited. 

Overall, the shift to newer refrigerants is likely to be a worthwhile investment. Improved efficiency often brings savings, and this change supports a more sustainable future for everyone.

What Are the Benefits of Switching to Low-GWP Refrigerants?

Switching to low-GWP refrigerants comes with several benefits:

Lower Environmental Impact

Low-GWP refrigerants produce fewer greenhouse gas emissions. This helps reduce pollution and slows down climate change. Using these refrigerants means we’re making a positive impact on the environment.

Better Energy Efficiency

Many low-GWP refrigerants, like R-32, are more energy-efficient than older options like R-410A. This means that new systems not only help lower your energy bills but are also gentler on the environment.

Prepared for Future Standards

Choosing a system with low-GWP refrigerants helps prepare your home for the future, as new regulations will continue to favor eco-friendly options. This way, you’re investing in a system that’s built to last.

These benefits make switching to low-GWP refrigerants a smart and environmentally friendly choice for homeowners.

What Homeowners Can Do to Prepare

To prepare for the 2025 refrigerant changes, consult an HVAC professional to assess your system’s condition and discuss potential upgrades. Checking your system’s age and efficiency is especially important, as older units may already be due for replacement to ensure reliable performance. 

Staying on top of maintenance helps you avoid unexpected issues and ensures a smooth transition if a new system is needed soon. Homeowners can also start budgeting for an upgrade, as the shift to low-GWP refrigerants is part of a broader move toward eco-friendly home system.

Adopting an Eco-Friendly HVAC System

The 2025 HVAC refrigerant change is part of a global push to reduce greenhouse gases and make cooling systems more eco-friendly. Although R-410A will be phased out in new systems, there’s no need to replace your current unit immediately. When it’s time for an upgrade, you’ll have options that are both efficient and better for the environment.

FAQs About HVAC Refrigerant Change

What refrigerant is being phased out in 2025?

In 2025, R-410A, a common refrigerant used in many HVAC systems, will be phased out for new systems. This change is part of a shift toward more eco-friendly refrigerants with a lower impact on the environment.

What will happen to R-410A refrigerant after 2025?

R-410A will still be available for existing HVAC systems, so there’s no need to worry if your system uses it. However, production may gradually decrease as new systems switch to eco-friendly refrigerants. Over time, this could mean R-410A might become a bit more expensive or harder to find.

Are the new low-GWP refrigerants safe to use?

Yes, absolutely! The new refrigerants, like R-32 and R-454B, have been thoroughly tested and meet safety standards. They work effectively in residential HVAC systems and are safe for home use.

Will these refrigerant changes affect my HVAC system’s performance?

Not at all! The new refrigerants cool just as well as the older ones. In fact, many of them are designed to be more energy-efficient, which could even help lower your energy bills over time.

How does this change benefit the environment?

Switching to low-GWP refrigerants reduces greenhouse gas emissions, which helps slow down global warming. This change is part of a global effort to make cooling systems more environmentally friendly and sustainable.

Can I retrofit my current HVAC system to use the new refrigerants?

Most existing systems aren’t designed to work with the new refrigerants, so retrofitting isn’t typically recommended. When you’re ready for a new system, it will come with the updated, eco-friendly refrigerant.
