One of the most eco-friendly decisions homeowners can make is upgrading your HVAC system to one that uses A2L refrigerant. If you’ve been thinking about replacing your home heating and cooling system, you may be able to make this environmentally-friendly switch starting in 2025. Here’s why switching to an A2L refrigerant system benefits both the environment and your wallet.
What is A2L Refrigerant?
A2L refrigerants are low global warming potential (GWP) refrigerants that offer a more environmentally friendly option than older, high-GWP alternatives like R22 and R-410A. These newer refrigerants are designed to reduce greenhouse gas emissions while still providing efficient cooling for residential and commercial properties.

5 Reasons to Switch to A2L Refrigerants ASAP
1. Avoid future HVAC supply chain issues
In 2020, Congress enacted the American Innovation and Manufacturing (AIM) Act which establishes a framework for phasing out specific high-global-warming-potential hydrofluorocarbons (HFCs), such as R410A. Starting in 2025, newly produced residential and light commercial air conditioners and heat pumps must incorporate the new, eco-friendly refrigerants. Equipment produced before this date will have a grace period allowing for installation until January 1, 2026.
As more countries and manufacturers phase out older refrigerants with high GWP, supply chain disruptions are likely to impact the availability of parts and servicing for older HVAC systems. By upgrading to an A2L refrigerant system early, you avoid the risk of delays and price hikes associated with maintaining outdated technology.
Moreover, as the industry shifts to adopt A2L systems, older systems will become more expensive to service and maintain. You’ll be future-proofing your home by upgrading sooner, ensuring that replacement parts and service expertise are readily available.
2. Positive environmental impact
Older HVAC systems typically use refrigerants with high GWP, which contribute to global warming and climate change when released into the atmosphere. A2L refrigerants have a significantly lower GWP, meaning they are much less harmful if they happen to leak.
By switching to a system that uses an eco-friendly refrigerant, you’re directly contributing to the reduction of carbon emissions and lessening your environmental footprint. As global regulations tighten, making the switch now ensures that your home’s HVAC system is compliant with future standards, reducing the likelihood of costly retrofits down the line.
3. Energy efficiency leads to lower energy bills
A2L refrigerant systems are not only better for the planet, but they’re also more energy-efficient. Many homeowners see a reduction in their energy bills after getting an HVAC system upgrade with A2L refrigerant. These systems are designed with the latest technologies to maximize energy efficiency, ensuring that you stay comfortable in your home without consuming excess energy.
4. Incentives and rebates available for early adopters

Switching to an A2L refrigerant system sooner rather than later can also make you eligible for various federal, state, and local rebates or tax credits. These incentives aim to encourage homeowners to adopt environmentally friendly technologies and reduce their carbon footprint. By acting now, you can take advantage of these programs and offset the initial cost of upgrading your HVAC system.

Check with your local HVAC contractor or government programs for the latest information on available incentives for energy-efficient systems.
5. Enhanced performance and longevity
A2L refrigerant HVAC systems are designed with modern features that enhance the overall performance of your home’s heating and cooling. These systems often come with smart technologies that allow for greater control and optimization of your home’s climate. Not only will your HVAC system run more efficiently, but it’s likely to have a longer lifespan compared to older systems.
Make the Switch to A2L
Switching to an A2L refrigerant HVAC system is a smart investment that benefits both the environment and your finances. With energy efficiency, lower emissions, potential rebates, and long-term savings, there’s no reason to delay making the switch. Act early to ensure that your home is prepared for the future while enjoying a more sustainable and cost-effective heating and cooling solution.
