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 or heat pumps as well as other appliances must make use of refrigerants with Global Warming Potential (GWP) lower than 700 before January 1st, 2025. This is part of a larger attempt to decrease the amount of hydrofluorocarbons (HFCs) which are powerful greenhouse gases.

The industry standard currently in use, R-410A, which has been widely used for its safety and efficiency, will be phased out. Manufacturers are turning to alternatives such as R-32 and R-454B. Both are both GWP-based, with GWP values of around 500 and 700, respectively. These new refrigerants, known as A2L refrigerants, have been designed to provide high performance while significantly reducing environmental impacts.

Understanding Global Warming Potential

The GWP is used to evaluate the heat-trapping capacity of various gases over a period of 100 years. The lower the number of GWP, the lower heat is absorbed by the atmosphere by refrigerants during its entire life cycle which includes production, transportation usage, and then removal. HVAC companies are seeking to reduce their contribution to greenhouse gas emissions worldwide by switching to refrigerants that have low GWP. These gases currently account for 7.8 percent of the total emissions.

The Cost Implications

One of the immediate and obvious effects of these new regulations is an increase in the cost of HVAC units. According to experts in the field that the price of cooling units could increase by between 20 and 30 percent. The increase could be due to various factors:

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

2. Manufacturing changes: To comply with the regulations, factories have to retool their manufacturing processes and invest in the latest technology. This will increase the cost of production.

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

4. Training and certification: HVAC technicians will need additional training to handle the new refrigerants safely which could result in higher cost of labor.

For homeowners, this could mean paying between $6,000 and $8,000 for the new HVAC system and installation. Some HVAC manufacturers offer rebates which will help offset the increase in cost.

The phase-out of current systems

Although the new regulations will are mainly affecting new HVAC systems, they may also affect existing units. R-410A production as well as that of other gases with high-GWP will be significantly reduced. This will result in an increase in the supply and a rise in the prices for these refrigerants that are older.

The phase-out poses a problem for homeowners with older HVAC systems. Repair and maintenance of these systems will become more expensive as the availability of R-410A decreases. The increased cost of servicing may make a complete replacement of the system more cost-effective for homeowners who have older systems.

Technological Advancements
