The New Refrigerant Standards

The new regulations are centered around a requirement to use refrigerants that have a less global warming Potential. Starting January 1st, 2025 all new residential air conditioners 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.

R-410A will soon be phased out as it is no longer an industry-wide standard. Manufacturers are now shifting to alternative refrigerants such as R-32 or R-454B, with GWP values between 500 and 600. These brand new A2L refrigerants are designed to deliver high-performance with less environmental impact.

Understanding Global Warming Potential

The GWP is used to evaluate the heat-trapping capacity of different gases for a period of 100 years. The lower the GWP number, the less heat a refrigerant traps in the atmosphere throughout its lifecycle which includes production, transportation, use as well as removal. In switching to low-GWP refrigerants in the HVAC industry is seeking to reduce its contribution to greenhouse gas emissions, which is currently around 7.8% of global emissions.

The Cost Implications

One of the most immediate and evident outcomes of these new regulations is an increase in the price of HVAC units. According to experts in the field that the price of air conditioning units may increase by between 20 and 30%. The increase could be due to several factors:

1. New Technology: The shift to A2L refrigerants requires redesigning HVAC systems, with new components and security features.

2. Manufacturing adjustments: To comply with regulations, factories must retool their manufacturing processes and invest in modern technologies. This will increase the cost of production.

3. Supply Chain disruptions This change could lead to temporary shortages in materials and components as well as higher costs.

4. Training and certification: HVAC technicians will require additional education to manage the new refrigerants with care and efficiently, which could lead to increased cost of labor.

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 will help offset the increase in costs.

Transition out of the current systems

The new regulations will not just affect the construction of new HVAC units but also existing ones. R-410A production, as well as other gases with high GWP will be significantly reduced. This will result in an increase in the supply and an increase in prices for the older refrigerants.

This phase-out creates a challenge for homeowners with old HVAC units. Maintenance and repair of these systems will become more expensive as the availability of R-410A reduces. The increasing costs for servicing could make a total system replacement more cost-effective for homeowners who have older systems.

Technological Advancements
