Condo HVAC In 2025: Transitioning to R32 & R454B Refrigerants

As the Condo HVAC industry prioritizes environmentally friendly solutions, the transition from R410A to newer refrigerants, R32 and R454B, marks a significant change in 2025. These next-generation refrigerants reduce environmental impact and maintain the high efficiency and safety standards that modern condos and properties demand.

If you’re a condo owner or property manager, understanding these changes is crucial for planning HVAC upgrades such as Condo Heat pumps, ensuring regulatory compliance, and optimizing long-term efficiency. Here’s a comprehensive guide to help you navigate this shift and make informed decisions.

Last Call For R410A Heat Pumps -Key Milestones for the R410A Phase-Down

The transition from R410A is part of a global effort to reduce greenhouse gas emissions. The U.S. Environmental Protection Agency (EPA) has set a phased schedule for this change:

• 2023-2024: A 10% gradual reduction in R410A production and imports, encouraging manufacturers to adopt lower-GWP refrigerants.
• 2025: A ban on manufacturing new residential and light commercial HVAC equipment using R410A. By 2029, There would be a 40% decrease in production of R410 equipment.
• 2030-2036: A complete phase-out of R410A in all new HVAC equipment while existing systems will still be serviceable.

Attention Condo Owners & Property Managers: Why to Upgrade Now?

If your condo’s HVAC system uses R410A, there’s no immediate need to worry. Parts and refrigerants will remain available for maintenance for many years. However, if you’re planning an upgrade, consider R32 or R454B, a smart move to future-proof your property while benefiting from increased efficiency.

Ultimately If your condo HVAC system is nearing the end of its lifespan, upgrading to an R32 or R454B system can save you future headaches. Here are three (3) reasons to consider upgrading in 2025:

1. Regulatory Compliance: By 2036, the parts available to service the old R410A product will start to become obsolete or diminish since they are no longer to be manufactured. Therefore, keeping stock or building-wide retrofit will ensure the property stays ahead of regulatory changes.
2. Price Increase: With new products going on assembly lines, it is expected that the price of new heat pumps and all HVAC systems using new refrigerant will be increased to offset the cost of research and development and transition into a new phase of manufacturing. Pre-purchase systems before new prices take effect next year in 2025 would be a good idea.
3. Energy Savings: With up to 12% improved efficiency, these refrigerants reduce energy consumption, lowering utility bills—a major selling point for condo boards and tenants.

R32 & R454B Difference Versus R410A Refrigerant

Both R32 and R454B have emerged as top alternatives to R410A, offering improved efficiency and reduced environmental impact. Here’s how they compare:

1. Lower Global Warming Potential (GWP)

• R410A GWP: 2088
• R32 GWP: 675
• R454B GWP: 466

The lower the GWP, the less the refrigerant impacts climate change. R454B, for example, reduces GWP by 78% compared to R410A, aligning with global sustainability goals.

2. Higher Efficiency

R32 and R454B are approximately 12% more efficient than R410A. This means better cooling performance with lower energy consumption—a significant benefit for reducing utility costs in condos and commercial properties.

3. Mild Flammability

Both R32 and R454B are classified as A2L refrigerants, meaning they are mildly flammable. While this might sound concerning, the risk is minimal when proper safety measures are in place. They only ignite in the presence of an external flame, and the flame extinguishes when the source is removed. Modern HVAC systems are designed with built-in safety protocols to mitigate these risks.

For an example, check out this video at 12:10 to see how A2L refrigerants ignite under controlled conditions.

For Technicians: Preparing for A2L Refrigerants

The transition to R32 and R454B requires updated tools and training. Here’s what technicians need to know:

• Tool Compatibility: Ensure gauges, leak detectors, and recovery machines are rated for A2L refrigerants.
• Safety Measures: Familiarize yourself with the labelling and integrated safety features of R32 and R454B systems.
• Minimal Adjustments: Most system components, such as compressors and filter driers, are already compatible with R454B, minimizing the need for major redesigns.

Frequently Asked Questions

1. Can R454B refrigerant be used in R410A systems?
No, R454B cannot be retrofitted into existing R410A systems. Components like compressors and metering devices must be explicitly rated for R454B. Since this is a major retrofit, replacing the whole HVAC system would be best.

2. Will technicians notice significant differences when working with R454B systems?
Not significantly. While new stickers, labels and safety features are required, the overall design and operation of R454B systems are similar to R410A.

3. Should I replace my R410A system now?
If your system is nearing the end of its lifespan, it’s worth upgrading to an R32 or R454B HVAC system. However, maintenance and repairs will remain manageable for years if it’s relatively new.

Can HVAC companies sell or install air conditioner or heat pump units with R-410A after January 1, 2025?

Starting January 1, 2025, manufacturing HVAC replacements using R-410A equipment will no longer be permitted. However, no restrictions exist on selling parts needed to service existing R-410A split systems, such as compressors, condensers, indoor coils, or evaporators. Please also note there is a 3-year sell-through period before next year’s deadline. This means that products imported or manufactured before January 1, 2025, R-410A may be sold, distributed, or exported until January 1, 2028.

Conclusion: The Path to a Greener HVAC Industry

The transition to R32 and R454B is a pivotal moment for the HVAC industry. These refrigerants reduce environmental impact and deliver improved efficiency and long-term viability. Staying informed and proactive for condo owners and property managers ensures smooth upgrades and optimized building performance. Whether you’re upgrading now or planning for the future, R32 and R454B offer a sustainable and reliable path forward.
