The New Refrigerant Standards

The new regulations are centered around a requirement to use refrigerants with a lower Global Warming Potential. Starting January 1st, 2025, all new residential air conditioners and heat pumps must utilize refrigerants with GWPs below 700. This move is part of a broader attempt to decrease the amount of hydrofluorocarbons (HFCs), which are potent greenhouse gases.

The current industry standard, R-410A, which has been widely used for its efficiency and safety is scheduled to be eliminated. Instead, manufacturers are shifting to alternatives such as R-32 and R-454B. Both are both GWP-based, with GWP values of around 500 and 600, respectively. These new refrigerants, known as A2L refrigerants, are engineered to ensure high-performance while significantly reducing environmental impact.

Understanding Global Warming Potential

The GWP allows you to assess the capacity of heat trapping of different gases for the duration of 100 years. The lower the GWP value is, the less heat a refrigerant is able to trap in the atmosphere throughout its entire lifecycle, which comprises production, transport, use and disposal. HVAC companies are trying to decrease their contribution to greenhouse gas emissions worldwide by switching to refrigerants that have low GWP. They currently account for 7.8% of all emissions.

The Cost Implications

The price of HVAC units will be increased immediately and clearly as a result of these new regulations. According to experts in the field the price of cooling units could increase by 20-30%. This increase is attributed to various reasons:

1. New technology The switch to A2L refrigerants means that HVAC systems using new components and safety features.

2. Manufacturing Changes Factories have to retool and invest in new technology to be in compliance with the new regulations, and 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 training in handling the new refrigerants safely and efficiently, which could lead to increased labor costs.

For homeowners it could be between $6,000 to $8,000 for an HVAC system that is new and requires installation. Certain manufacturers offer rebates that could help offset the higher cost.

The Phase-Out of Current Systems

The new regulations won't just affect new HVAC units, but also existing ones. Production of R-410A and other high-GWP refrigerants will be significantly reduced, leading to less supply as well as an increase in prices for these old refrigerants.

The gradual elimination of R-410A is problems for homeowners that have older HVAC systems. Repair and maintenance of these systems will become more costly as the supply of R-410A decreases. The rising costs of servicing could make a total replacement of the system more cost-effective for homeowners with older systems.
