The New Refrigerant Standards

The new rules are centered around the requirement of using refrigerants with a lower global warming Potential. All new residential air conditioners as well as heat pumps and other appliances should make use of refrigerants with Global Warming Potential (GWP) less than 700 by January 1, 2025. This is part of an overall attempt to decrease the amount of hydrofluorocarbons (HFCs), which are greenhouse gases that have a high GWP.

R-410A is scheduled to be phased out, as it is not a common industry standard. Instead, manufacturers are shifting to alternatives such as R-32 and R-454B, which are both GWP-based, with GWP values of 500 and 650, respectively. These refrigerants, referred to as A2L refrigerants, have been designed to provide high performance while significantly reducing environmental impacts.

Understanding Global Warming Potential

The GWP value is a measure used to measure the capacity to trap heat of various gases over a time period of 100 years. The lower the GWP value, the less heat a refrigerant traps in the atmosphere during its entire lifecycle, which comprises production, transportation, use as well as removal. In switching to low-GWP refrigerants and reducing their use, the HVAC industry is aiming to decrease its contribution to greenhouse gas emissions. It is currently about 7.8 percent of the global emissions.

The Cost Implications

The cost of HVAC systems will rise immediately and significantly because of the new rules. According to experts in the field the price of cooling units could increase by between 20 and 30 percent. The reason for this is various factors, including:

1. New technology The transition to A2L refrigerants means that HVAC systems, with new components and safety features.

2. Manufacturing adjustments: To comply with rules, factories need to modify their production processes and invest in new technologies. This will increase the cost of production.

3. Supply Chain disruptions The change could cause temporary shortages and increased costs for materials and components.

4. Training and certification: HVAC technicians will require additional education to manage the new refrigerants in a safe manner, potentially leading to higher labor costs.

For homeowners, this could mean paying between $6,000 to $8,000 for a new HVAC system with installation. However, some manufacturers may offer rebates to help reduce the cost of these upgrades.

The Phase-Out of Current Systems

Although the new regulations will primarily affect new HVAC systems, they will also impact existing systems. R-410A production as well as that of other gases with high-GWP will be drastically reduced. This will lead to an increase in supply and an increase in prices for the older refrigerants.

The gradual elimination of R-410A is a problem for homeowners who are using older HVAC systems. Repair and maintenance of these systems will be more expensive as the supply of R-410A decreases. The rising costs of servicing could make a total system replacement more cost-effective for homeowners who have older systems.
