The New Refrigerant Standards

The new regulations revolve around a requirement to use refrigerants with a lower global warming Potential. All new residential air conditioners or heat pumps as well as other appliances should make use of refrigerants with a Global Warming Potential (GWP) lower than 700 by January 1 2025. This move is part of a broader plan to reduce the use of hydrofluorocarbons (HFCs) that are greenhouse gases that have a high GWP.

The current industry standard, R-410A, which has been widely utilized due to its effectiveness and safety is scheduled to be eliminated. Manufacturers are now shifting to alternatives like R-32 or R-454B that have GWP values between 500 and 700. The new A2L refrigerants have been designed to provide high performance with less environmental impact.

Understanding Global Warming Potential

The GWP can be used to evaluate the heat-trapping capacity of different gases for the duration of 100 years. The lower the value of GWP, less heat is trapped in the atmosphere by a refrigerant throughout its entire life which includes production, transportation usage, and then removal. In switching to low-GWP refrigerants in the HVAC industry is aiming to decrease its greenhouse gas emissions, which is currently about 7.8 percent of global emissions.

The Cost Implications

The cost of HVAC systems will rise immediately and significantly due to these new regulations. According to experts in the field, the cost of cooling units could increase by between 20 and 30%. This is due to various reasons, such as:

1. New technology The transition to A2L refrigeration requires redesigning HVAC system, with new components and security measures.

2. Manufacturing Improvements Factories must revamp their processes and invest in the latest technology to be in compliance with the regulations, increasing production costs.

3. Supply Chain disruptions The disruption could result in temporary shortages and higher costs for materials and components.

4. Training and certification: HVAC technicians will require additional training in handling the new refrigerants in a safe manner and efficiently, which could lead to increased cost of labor.

This could cost homeowners between $6,000-$8,000 when they install for a new HVAC system. Some manufacturers might offer rebates to pay for these higher costs.

The Phase-Out of Current Systems

While the new regulations mostly affect new HVAC systems, they may also affect existing systems. Production of R-410A and other high-GWP refrigerants will be drastically reduced, leading to an increase in supply and an increase in prices for these older refrigerants.

The gradual elimination of R-410A is an issue for homeowners who are using older HVAC systems. As the amount of R-410A dwindles, maintaining and repairing the system will become more expensive. Homeowners who have systems more than 10 years old may discover that the increasing costs of maintenance makes replacing the entire system affordable in the long run.
