Your Guide to the 2025 HVAC Refrigerant Phase-Out

The Environmental Protection Agency (EPA) mandated that starting January 1st, 2025, only eco-friendly refrigerants will be used in newly manufactured HVAC systems. Here’s what this means to you as a homeowner in the Los Angeles, CA area.

The Refrigerants Being Phased Out

In 1987, the United Nations finalized a global agreement to protect the stratospheric ozone layer by phasing out the production and consumption of ozone-depleting substances. This agreement, known as the Montreal Protocol, targeted substances used in products such as air conditioners, refrigerators, aerosols, and fire extinguishers.

The Montreal Protocol’s goal was to mitigate global warming. The ozone layer filters out harmful ultraviolet radiation from the sun, which is known to reduce agricultural productivity, disrupt marine ecosystems, and increase the prevalence of skin cancer and cataracts.

The Montreal Protocol was scheduled to be implemented in different stages as technology improved. After the Kigali Amendment was adopted in 2016, the next milestone in this effort was the 2025 HVAC refrigerant phase-out. This phase-out targets hydrofluorocarbons (HFCs), which are powerful greenhouse gases that, while less damaging to the ozone layer than their predecessors, contribute significantly to global warming.

The refrigerants affected in this phase-out include R-410A and R-22. Their production, importation, and consumption will be reduced to 10% of their current baseline levels. By 2030, the phase-down should be 0.5% of their baseline levels if the phase-out is not complete by then.

The New Refrigerants to Be Used

The new refrigerants to be used in HVAC systems include R-32, R-454B, and R-1234yf. It’s important to note that R-32 is a hydrofluorocarbon refrigerant with lower global warming and ozone-depleting potential than the outgoing R-410A. R-454B and R-1234yf are hydrofluoroolefin refrigerants with extremely low global warming potential.

These new refrigerants are also quite energy efficient. They have improved thermodynamic properties, which means they can transfer heat more effectively within an HVAC system. As a result, the system won’t have to work harder or longer to condition the air inside your Los Angeles home.

How Refrigerant Changes Will Affect You

The 2025 HVAC refrigerant change will affect you in several ways, including:

System Replacement

If your system uses either R-22 or R-410A refrigerant, start planning for a replacement. In case of a refrigerant leak, it will be challenging to get these refrigerants because they are illegal to produce or import. The repair costs may increase as availability diminishes. It would be more economical to invest in a new system.

While buying a new system, consider the 2030 final HFC phase-out. Even though R-32 refrigerant is acceptable now, it is still a hydrocarbon. If you are planning to use your next HVAC system for its entire lifespan (15 to 20 years), opt for hydrofluoroolefin refrigerants instead.

Increased Costs

Developing new HVAC systems to accommodate the new refrigerants requires modern technology and updated manufacturing processes. The refrigerants themselves also cost a little more to produce than their predecessors. Therefore, expect slightly higher upfront costs when buying a new AC system. Fortunately, HVAC companies are adopting financing options to help spread out these expenses and make it easier for homeowners to transition to better HVAC systems.

Energy Efficiency

Newer HVAC systems will be more affordable to run. In fact, the EPA raised the minimum SEER2 ratings for modern systems. Homeowners in the Los Angeles area require systems with at least a 14.3 SEER2 rating.

If you buy an air conditioner with at least a 16.0 SEER2 rating, you may be eligible for a tax credit of up to $1,200 when paired with a qualifying gas furnace. For heat pumps, the required rating for tax credits is 15.2 SEER2 and 8.1 HSPF2.

Sustainability

The new refrigerants will help you reduce your carbon footprint. If they leak, they won’t have such a significant negative impact on the environment compared to their predecessors. You’ll play a vital role in preserving the planet for future generations.

Longer Lifespan

Modern HVAC systems with new refrigerants will generally last longer. As mentioned, the new refrigerants are very efficient at heat transfer, which means the HVAC system will generally have an easier time conditioning your air. A system that doesn’t struggle experiences less wear and tear on its components and, thus, a longer lifespan. You may even notice manufacturers offering longer warranties (over 10 years) because they are confident in their new and improved units.

Enhanced Home Safety

Another advantage of the newer refrigerants is that they’ll enhance home safety. They are classified as mildly flammable, and their toxicity rating is A, which is very low. You can rest assured that even if your system is overheating, the refrigerant may not catch fire because they are quite difficult to ignite.

Considerations When Making the Switch

Ensure the technician guiding you through the HVAC transition process is trained to work with the new refrigerants. These newer systems can be more complex and may require specialized knowledge and tools for installation and maintenance.

Proper HVAC installation eliminates over 50% of potential issues that arise over the lifespan of the system. On the other hand, proactive AC maintenance will not only keep your system operating efficiently and safely but also prevent breakdowns and extend its lifespan.

Additionally, stay updated on the latest HVAC news and laws in Los Angeles, CA. Don’t miss out on potential government rebates and incentives after installing an energy-efficient system.

Other Benefits of Installing an Advanced HVAC System

Besides protecting the environment and enhancing energy efficiency, modern systems come with other advanced features, such as smart thermostats with learning capabilities, improved air quality features, integration with home systems, and predictive maintenance.
