New Refrigerant 2025

New Refrigerant 2025

Refrigerants are necessary to keep HVAC systems running smoothly, ensuring homes and businesses stay comfortable year-round. These substances make it possible for air conditioners, heat pumps, and other HVAC equipment to cool or heat the air effectively.

Starting this year, the HVAC industry will significantly change by transitioning to new refrigerants with a lower global warming potential (GWP), as required by the American Innovation and Manufacturing Act of 2020. These new refrigerants are designed to reduce greenhouse gases and have a more positive impact on the environment.

For homeowners and businesses in Carrollton, TX, these changes mean better energy efficiency, lower utility bills, and compliance with Environmental Protection Agency (EPA) regulations.

If you’re considering upgrading your current HVAC system or need guidance regarding these future regulations, call Lex Air Conditioning & Heating at (972) 217-8955 or contact us online today.

New EPA Refrigerant Regulations (2025)

The US Environmental Protection Agency (EPA) plays a major role in protecting the environment by regulating harmful chemicals, including those used in HVAC systems. Starting in 2025, new environmental regulations aim to reduce the use of potent greenhouse gases, including hydrofluorocarbons (HFCs), found in current refrigerants.

This initiative is part of a global agreement to combat climate change by gradually phasing out refrigerants with high global warming potential, like R-410, and replacing them with eco-friendly refrigerants, such as R-454B and R-32, which have significantly lower GWP.

These changes, established under the American Innovation and Manufacturing Act of 2020, help reduce greenhouse gasses, protect the ozone layer, and promote energy efficiency in HVAC equipment.

What is the New Refrigerant?

The EPA mandated that HVAC manufacturers switch to lower GWP refrigerants in 2025 as part of new regulations to minimize the environmental impact of greenhouse gases.

These newer refrigerants, including R-454B and R-32, replace older options like R-410A to create a more sustainable future. Here’s what you need to know about these eco-friendly refrigerants and how they benefit HVAC systems:

R-454B

R-454B is a new type of refrigerant that will replace the current R-410A refrigerant used in HVAC systems. It’s a blend of two components: R-32, a hydrofluorocarbon (HFC), and R-1234yf, a hydrofluoroolefin (HFO). This combination gives R-454B a much lower global warming potential (GWP), meaning it traps less heat in the atmosphere compared to older refrigerants.

Using R-454B in your HVAC system can mean better energy efficiency, lower utility bills, and a smaller carbon footprint. While it’s considered mildly flammable, the refrigerant is kept within a closed system and is not exposed to ignition sources. These safety features ensure it can be safely used in commercial and residential HVAC systems.

R-32

R-32 refrigerant, also known as difluoromethane, is a single-component hydrofluorocarbon (HFC) with significant environmental benefits. Compared to older options like R-410A, it has a zero ozone depletion potential (ODP) and a much lower global warming potential (GWP).

When used in an air conditioner or heat pump, R-32 improves system performance by operating more efficiently and requiring less refrigerant to achieve the same cooling or heating power. This can translate into noticeable energy savings on your utility bills while also reducing the release of harmful greenhouse gasses into the environment.

Why Are These Changes Happening?

This year’s changes in the HVAC industry are part of a global effort to reduce harmful greenhouse gases and protect the environment.

The American Innovation and Manufacturing Act of 2020 authorized the US Environmental Protection Agency to phase out refrigerants with high levels of hydrofluorocarbons (HFCs) by 2036. The EPA mandated a significant change to meet these environmental goals: starting in 2025, new HVAC systems must use refrigerants with a global warming potential (GWP) of 700 or less.

The switch to low GWP refrigerants helps combat climate change and paves the way for more environmentally friendly solutions in new HVAC systems.

New EPA Refrigerant Regulations (2025)

What Does This Mean for Your HVAC System?

If your current system uses R-410A refrigerant, there’s no need to replace it right away. The EPA’s plan to phase down older refrigerants will happen gradually over the next decade, allowing homeowners plenty of time to switch to a new HVAC system when it makes sense for their home or budget.

For the foreseeable future, our Carrollton HVAC professionals can maintain and service your system using existing supplies of older refrigerants. This gives you more flexibility to schedule your upgrade to a high-efficiency system, ensuring a smoother transition when the time comes.

How Will This Impact You?

As a homeowner in Carrollton, TX, you don’t need to replace your current HVAC system immediately, but there are good reasons to consider upgrading to a new system.

With Texas summers bringing intense heat, having whole-home systems that provide reliable performance and improved energy efficiency can make a big difference in your comfort and energy bills. New equipment designed for the latest refrigerants helps the environment and operates more efficiently, which can lead to significant cost savings over time.

By planning ahead and upgrading to a modern system, you’ll avoid frequent repairs and potential service issues in the future while enjoying the long-term benefits of a more sustainable and efficient HVAC system.

R-454B Price

Although the price of R-454B refrigerant is higher than older options like R-410A, it offers significant benefits for the environment and your HVAC system’s performance.

R-454B is mildly flammable and classified as an A2L refrigerant, so careful handling is important, and specific installation requirements must be followed. HVAC systems using A2L refrigerants typically require a refrigerant detection system to monitor refrigerant concentration and quickly identify any refrigerant leaks.

While the initial cost of R-454B and its associated safety measures might be higher, its high efficiency and lower environmental impact make it a smart choice for sustainable HVAC systems.

R-32 Price

R-32 refrigerant is often considered a cost-effective choice for homeowners because it requires less refrigerant to cool the same space compared to older options like R-410A.

This means your HVAC system can operate more efficiently using less refrigerant, which helps keep operating costs down. Its simpler composition and availability make it an affordable and sustainable solution for new systems.

How Much is 410a?

The cost of R-410A refrigerant ranges from $40 to $75 per pound. This price can vary based on location, demand, and the size of your HVAC system.

Remember that the EPA restricts the purchase and handling of refrigerants like R-410A to certified HVAC professionals. If your system needs a recharge, you’ll need to hire a Carrollton AC Repair technician to ensure the work is done safely and complies with building codes and EPA regulations.

Low GWP Refrigerants

Do New AC Units Come With Refrigerant?

Yes, new air conditioning units typically come pre-charged with refrigerant, and starting in 2025, each new HVAC system will be manufactured using low GWP refrigerants like R-454B or R-32. These newer refrigerants are designed to reduce greenhouse gas emissions and comply with updated environmental regulations.

Most units come pre-filled with enough refrigerant to operate efficiently under standard installation conditions, but if your system requires longer refrigerant lines or other modifications during installation, additional refrigerant might be needed.

A licensed HVAC professional will ensure your system is properly charged and set up to meet the installation requirements for safe and efficient operation.

Do I Need to Change the Refrigerant in My Existing System?

No, you don’t need to change the refrigerant in your existing system if it’s working properly. Systems that use refrigerants like R-410A can still be serviced and maintained as long as those refrigerants are available. However, since R-410A is being gradually replaced with low-GWP refrigerants, future repairs might become more expensive as these older refrigerants become harder to find.

How To Change Refrigerant in AC

If you’re considering switching to new refrigerants to meet the updated EPA regulations, it’s important to know that you can’t do it yourself. Refrigerant replacement requires a licensed HVAC professional, as handling refrigerants is regulated for safety and environmental reasons.

Additionally, current HVAC systems that use R-410A refrigerant are usually incompatible with new refrigerants like R-454B or R-32 without significant modifications. In most cases, it’s more practical to invest in a new HVAC system designed specifically for these newer refrigerants. This ensures your system operates efficiently and complies with the latest standards. A Carrollton HVAC technician on or team can help you explore your options and make the best choice for your home.
