Understanding the 2025 HVAC Refrigerant Changes for Homeowners
Starting in 2025, the HVAC industry is transitioning to using A2L refrigerants in heating and cooling systems. This refrigerant change is part of a larger regulation to reduce the impact on the environment. At Mike Watson Heating & Cooling we understand that this sounds like a big shift in the industry to homeowners. However, homeowners can rest easy as this change won’t require immediate changes to most existing HVAC systems.
In this article, we answer top questions from homeowners and provide the information you need to stay ahead of this change.
What is HVAC Refrigerant?
Refrigerant is the chemical compound and substance HVAC systems use to move heat and keep indoor air comfortable. It circulates through coils and copper lines, changing from liquid to vapor and back again as it absorbs heat from inside your home and releases it outside.
Why is Refrigerant Important for My Air Conditioner?
Refrigerant is essential to any air conditioning or refrigeration system because it’s the substance that actually performs the cooling. Without refrigerant, your HVAC system wouldn’t be able to move heat or control indoor temperatures.
The Old R-410A Refrigerant Explained for Homeowners
R-410A is a type of refrigerant widely used in residential and commercial air conditioning systems manufactured from 2000 to the early 2020s. When rolled out, R-410A initially replaced older refrigerants like R-22 (also known as Freon) due to its environmental impact. Now, R-410A is also being phased down because of its environmental impact.
The Transition to A2L
To meet the EPA’s new standards, the industry will shift to lower-impact refrigerants. Most of these lower-impact compounds are classified as A2L refrigerants and are already used in millions of units around the world.
2025 Refrigerant Change: What is A2L?
A2L refrigerants are a family of refrigerants that are low in toxicity and have a lower environmental impact compared to older compounds. These new refrigerants are also considered “mildly flammable” and require updated safety codes, yet pose very little threat to homeowners.
Overall, the move toward A2Ls is part of a broader effort to reduce the environmental impact of HVAC systems and improve energy efficiency for homeowners.
The New Refrigerants Used in 2025
The two main types of A2L refrigerants used for residential cooling systems are R-454B refrigerant and R-32 refrigerant. Approximately 160 million units already use R-32 throughout the United States.
Common Questions About the Refrigerant Change
With the shift to new refrigerants on the horizon, homeowners have many questions. Here are some of the most common concerns about the change.
Will I need to replace my HVAC system because of A2L refrigerants?
Not necessarily. Starting in 2025 new HVAC systems will use A2L refrigerants. Existing systems that use R-410A or other refrigerants will still work as normal for the foreseeable future.
However, if you have an older system, it may be a good idea to start planning for an upgrade to a system that uses the newer refrigerants, as they will be the new standard.
Will the new A2L refrigerant affect my energy bills?
A2L refrigerants like R-32 and R-454B are known for being energy-efficient while providing effective cooling. If you’re installing a new system that uses A2L refrigerants, you could potentially see lower energy bills as a result.
Are A2L refrigerants safe for my home?
A2L refrigerants have been extensively tested and are safe for residential use. The new A2L refrigerants are low in toxicity and extremely difficult to ignite. In fact A2L refrigerants are often much safer than A3 refrigerants like propane or butane. Proper installation is still a must, as trained experts ensure the refrigerant safely circulates through your system.
Do I need to do anything to meet the new refrigerant regulations?
As a homeowner, you don’t need to worry about the regulations directly. However, starting in 2025, when you replace your HVAC system, you will be required to choose a unit that complies with the new laws. The licensed HVAC experts at Mike Watson Heating & Cooling can explain the A2L changes and help you get a new, properly installed unit.
