The New Refrigerant Standards

At the heart of these new regulations is a requirement to use refrigerants with less of a Global Warming Potential (GWP). All new air conditioners for residential use, heat pumps and other appliances are required to make use of refrigerants with Global Warming Potential (GWP) below 700 on January 1, 2025. It is part of an overall attempt to reduce hydrofluorocarbons which are potent greenhouse gases.

The industry standard currently in use, R-410A, which has been extensively used due to its effectiveness and safety it will be phased out. Manufacturers are now turning to alternatives like R-32 or R-454B with GWP values ranging from 500 to 700. These new A2L refrigerants have been designed to deliver high-performance with less environmental impact.

Understanding Global Warming Potential

The GWP value is a measure used to measure the heat-trapping capacity of different gases over a 100-year period. The lower GWP, less heat is absorbed by the atmosphere by refrigerants throughout its entire life that includes production, transport usage, and then disposal. HVAC companies are seeking to decrease their contribution to global greenhouse gas emissions by switching to low-GWP refrigerants. These gases are currently responsible for 7.8 percent of the total emissions.

The Cost Implications

One of the immediate and evident consequences of these new rules will be an increase in price of HVAC units. According to industry experts that the price of air conditioning units may increase by 20-30%. The increase could be due to many factors:

1. New technology The transition to A2L refrigerants will require a redesign of HVAC systems using new components and safety features.

2. Manufacturing Improvements: Factories need to retool and invest in new technologies to meet the new regulations, and increase production costs.

3. Supply Chain disruptions: The transition may create temporary shortages, and increase prices for materials and parts.

4. Training and Certification: HVAC Technicians will need additional training to handle the new refrigerants. This could lead to higher labor costs.

For homeowners it could be between $6,000 to $8,000 for the new HVAC system and installation. However, some manufacturers may offer rebates to offset these increased costs.

Phase-out of Current Systems

Although the new regulations will primarily affect the new HVAC units, they could also affect existing systems. Production of R-410A and other refrigerants with high GWP will be drastically reduced, leading to less supply and an increase in the cost of these older refrigerants.

The phase-out of R-410A presents a problem for homeowners who have older HVAC systems. As the availability of R-410A diminishes, maintaining and repairing the systems will become more expensive. Homeowners who have systems more than 10 years old might discover that the increasing cost of servicing can make a full system replacement more affordable in the long run.
