The New Refrigerant Standards

The new rules are centered around a requirement to use refrigerants that have a lower Global Warming Potential. All new air conditioners for residential use as well as heat pumps and other appliances should utilize refrigerants that have Global Warming Potential (GWP) below 700 before January 1, 2025. This move is part of a broader attempt to decrease the amount of hydrofluorocarbons (HFCs) that are potent greenhouse gases.

The industry standard currently in use, R-410A, which has been widely used for its effectiveness and safety is scheduled to be eliminated. Manufacturers are switching to alternative refrigerants such as R-32 and R-454B. Both have GWP values of around 500 and 700, respectively. The new A2L refrigerants are engineered to deliver high-performance with a reduced environmental impact.

Understanding Global Warming Potential

The GWP can be used to assess the capacity of heat trapping of various gases over up to 100 years. The lower the value of GWP, the lower heat is absorbed into the atmosphere by a refrigerant during its entire life cycle which includes production, transportation usage, and then removal. By transitioning to low-GWP refrigerants in the HVAC industry is aiming to decrease its greenhouse gas emissions, which currently accounts for about 7.8 percent of the global emissions.

The Cost Implications

The price of HVAC units will increase immediately and noticeably as a result of these new regulations. Experts from the industry predict that the cost of new HVAC units could increase between 20% and 30 percent. This is due to a number of factors, including:

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

2. Manufacturing Changes Factories must revamp their processes and invest in the latest technology to be in compliance with the new regulations, and increase the cost of production.

3. Supply Chain disruptions This change could cause temporary shortages of materials and components and higher prices.

4. Training and certification: HVAC technicians will require additional training in handling the new refrigerants with care which could result in higher labor costs.

The homeowners could pay between $6,000 and $8,000 for installation for a brand new HVAC unit. Some manufacturers offer rebates that could help offset the higher cost.

The Phase-Out of Current Systems

Although the new regulations will primarily affect new HVAC systems, they could affect existing HVAC units. The production of R-410A and other refrigerants with high-GWP will be drastically reduced, leading to an increase in supply as well as an increase in prices for these old refrigerants.

The gradual elimination of R-410A is problems for homeowners that are using older HVAC systems. Maintenance and repair of the systems will become more expensive as the availability of R-410A diminishes. The increasing costs for maintenance could make a full system replacement more affordable for homeowners who have older systems.
