New A2L Refrigerant Systems: What You Should Know

Have you heard about the new A2L refrigerant systems in Indianapolis? Starting January 1, 2025, all new residential air conditioners, heat pumps, and furnaces must use A2L refrigerants. To create energy-efficient systems and improve sustainability, this new refrigerant will replace the R-410A refrigerant currently in use. Vital Heating & Air, your trusted local HVAC company, is here to help you learn about the options that come with this significant industry change and make the transition as smooth as possible.

New Regulations

Why is this new requirement going into effect? The Environmental Protection Agency (EPA) is working on reducing climate change, and the new A2L refrigerants are one aspect of that endeavor. R-410A refrigerants have a much higher Global Warming Potential (GWP) than the replacement refrigerant. With these changes, homeowners will enjoy smaller carbon footprints and money savings on their energy bills. It's a win-win situation!

Refrigerant Detection Systems

One of the most notable differences between A2L refrigerants such as R-32 or R-454B and the current R-410A systems is the inclusion of a refrigerant detection system (RDS) in the newer models. These replacements are considered only mildly flammable, ensuring your safety, and perform with better energy efficiency. Our highly trained and experienced technicians have all the necessary tools and equipment to upgrade your home without hassle, providing you with a secure and protected environment.

The new A2L systems require a mitigation board that senses inside the evaporator cabinet for refrigerant leaks. If a refrigerant leak is detected, the heating equipment is turned off, and the blower is turned on to mitigate the refrigerant from the contained space. The latest furnace models are A2L compliant with built-in mitigation boards. If you own an older model, our friendly team will install an external mitigation board with sensors to upgrade your existing equipment.

Safety is Essential

Compressors, expansion valves, electrical components, and refrigerant charge sizes have all been redesigned for use with the new A2L refrigerants. Older units that use R410A and R22 refrigerants are not built to function with this new refrigerant. It is crucial to remember that mixing the two can lead to system damage and safety hazards. We want to ensure you are fully informed and aware of these implications. Always contact the professionals at Vital Heating & Air for your HVAC needs.
