The HVAC community has braced itself and prepared for a big shakeup as new air conditioning units will be forced to convert from traditional R410a refrigerant to R32 by the start of 2025. This is all part of global energy efficiency plans when it comes to cooling, and as a homeowner who will invest in a new AC system soon, understanding the implications means that you are better informed.
What Is R32 Refrigerant?
R32 (Difluoromethane) is a state-of-the-art refrigerant commonly used in air conditioning with some major environmental benefits and big energy savings. It's a hydrofluorocarbon (HFC) refrigerant, like its R410A predecessor, but with an even lower global warming potential than that old-school favorite. In fact, R32's GWP is about 1/3 of R410.
New HVAC units in the United States, European Union and many other areas across the world will require R32 -- rather than firm go-tos such as R410A with their much-hated greenhouse gas starting in 2025.
Why the shift to R32?
That's easy...environmental impacts are lessened.
Why is R32 becoming the preferred refrigerant for new generation HVAC systems at large?
Environmental: This one is a no brainer as it's clear that R32 has much less of an impact on the environment than R410A. The UN paper states that this makes it a better option to reduce greenhouse gas emissions.
Energy Efficiency: R32 has an extra feather of energy efficiency that fleshes out its reputation. R32 is more efficient in transferring heat compared to R410A, so air conditioning systems using this refrigerant work faster while consuming less electricity. The result - a lower cooling bill for homeowners!
Cost Efficiency: R32 is itself an economically priced refrigerant, but systems running on R410A also need more of the substance for their HVAC's. This eventually supports the decreased costs of manufacturing and maintenance over time.
Better Cooling Performance: Improved cooling efficacy: With R32 being natural refrigerant, it allows coolants to run at less pressure which means that design can be more optimal. This can allow for smaller, more efficient HVAC units that also perform better while still meeting various environmental regulations.
What should homeowners prepare for during the transition to R32?
Equipment Compatibility: Make sure your expert HVAC technician check's that your new systems are compatible with R32 refrigerant. The components of an air conditioning system, including compressors and piping, must be designed or adapted to handle R32.
Training and Certification: Handling R32 requires specialized training. While it is classified as mildly flammable (A2L), with proper safety protocols, it is safe to use. Guardian's experts have obtained the proper training for working with R32 and are prepared for all the new regulations and changes.
Maintenance and Servicing: For homeowners and business owners, it's important to be aware that older systems using R410A may not be compatible with R32. There are retrofitting options available but may void your warranty and a significant cost. It could be more cost effective to upgrade to a new R32 system.
Environmental and Regulatory Compliance: As R32 becomes the standard in the heating and air industry, staying compliant with regulations is critical. Homeowners should work only with licensed and certified professionals to make assure compliance and code standards are met.
The R32 refrigerant changes coming in 2025 are a crucial step forward for the HVAC industry from an environmental and energy efficiency perspective. The long term benefits of R32 such as lowered greenhouse gas emissions, improved energy efficiency and future cost savings will make a positive shift for the planet and homeowner. As most manufacturers have already made the necessary adjustments, discussing the new R32 systems with your System Design Expert is a great start to being part of the new innovative improvements for your home comfort.
