New Refrigerant Standards

The underlying principle of these new rules is a mandate to utilize refrigerants that have less global warming Potential (GWP). All new air conditioners for residential use or heat pumps as well as other appliances are required to utilize refrigerants that have a Global Warming Potential (GWP) below 700 before January 1st 2025. This move is part of a broader effort to phase down 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. Manufacturers are switching to alternative refrigerants such as R-32 and R-454B, both of which have GWP values of around 500 and 700 and 650, respectively. These new refrigerants, known as A2L refrigerants, are designed to provide high performance and significantly reduce environmental impact.

Understanding Global Warming Potential

GWP is a metric that is used to evaluate the ability to trap heat for different gases over a 100-year period. The lower GWP number is, the less heat a refrigerant captures in the atmosphere during its lifecycle which includes production, transport, use as well as disposal. HVAC companies are seeking to decrease their contribution to global greenhouse gas emissions by switching to refrigerants that have low GWP. They currently account for 7.8 percent of the total emissions.

The Cost Implications

The cost of HVAC systems will increase immediately and noticeably as a result of the new rules. According to industry experts, the cost of cooling units could increase by between 20 and 30 percent. The reason for this is several reasons:

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

2. Manufacturing Changes: Factories need to revamp their processes and invest in the latest technologies to comply with the rules, which will increase production costs.

3. Supply Chain Disruptions The disruption could create temporary shortages, and increase costs for materials and components.

4. Certification and Training: HVAC Technicians will require additional training in order to safely handle the new refrigerants, which could mean increased labor costs.

For homeowners it could be between $6,000 and $8,000 to purchase the new HVAC system and installation. However, some manufacturers may offer rebates to reduce the cost of these upgrades.

Phase-out of Current Systems

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

This phase-out presents a dilemma for homeowners with old HVAC units. As the amount of R-410A decreases, the cost of servicing and repairs to the systems will become more costly. homeowners with systems that are more than 10 years old may discover that the increasing costs of maintenance makes a full system replacement more affordable in the long run.

Technological Advancements
