New Refrigerant Standards

At the heart of these new rules is the requirement to utilize refrigerants that have a lower global warming Potential (GWP). Starting January 1, 2025, all new air conditioners for residential use and heat pumps will be using refrigerants that have a GWP lower than 700. It is part of an overall attempt to reduce hydrofluorocarbons which are potent greenhouse gases.

The current industry standard, R-410A, which has been widely utilized due to its efficiency and safety is scheduled to be eliminated. Manufacturers are presently turning to other refrigerants, such as R-32 or R-454B that have GWP values between 500 and 600. These new refrigerants are referred to as A2L refrigerants, have been designed to maintain high performance while significantly reducing environmental impact.

Understanding Global Warming Potential

The GWP metric is used to compare the heat-trapping capacity of different gases over a 100-year period. The lower the number of GWP, less heat is trapped in the atmosphere by refrigerants throughout its entire life that includes production, transport usage, and then removal. When switching to refrigerants with low-GWP in the HVAC industry is aiming to decrease its greenhouse gas emissions. This currently accounts for about 7.8 percent of the global emissions.

The Cost Implications

2. Manufacturing Improvements Factories must upgrade their equipment and invest in new technology to be in compliance with the new regulations, and increase production costs.

3. Supply Chain Disruptions to Supply Chain The disruption could result in temporary shortages and higher prices for materials and parts.

4. Training and Certification: HVAC technicians will require additional education to manage the new refrigerants with care, potentially leading to higher cost of labor.

For homeowners it could be between $6,000 and $8,000 for a new HVAC system with installation. Some manufacturers offer rebates that will help offset the increase in cost.

Transition out of the current systems

Although the new rules primarily affect new HVAC systems, they will affect existing HVAC systems. The production of R-410A and other high-GWP refrigerants will be significantly decreased, resulting in a decrease in availability and a rise in prices for these older refrigerants.

This phase-out creates a challenge for homeowners with old HVAC units. As the amount of R-410A diminishes, the maintenance and repair of the system will become more costly. The increasing costs for maintenance could make a full replacement of the system more cost-effective for homeowners with older systems.

Technological Advancements

The shift to refrigerants with low GWP isn't just about substituting one chemical with another. It's driving significant technological advancements within the HVAC industry:

Security features that are improved

A2L refrigerants, while being more sustainable, are mildly flammable. To combat this issue, the latest HVAC systems are going to incorporate advanced safety features.
