New Refrigerant Standards

The new regulations revolve around a requirement to use refrigerants with a lower Global Warming Potential. All new air conditioners for residential use as well as heat pumps and other appliances should make use of refrigerants with Global Warming Potential (GWP) lower than 700 before January 1st, 2025. This is part of an overall attempt to decrease the amount of hydrofluorocarbons (HFCs), which are greenhouse gases that have a high GWP.

The current industry standard, R-410A, which has been widely used for its efficiency and safety, will be phased out. Manufacturers are shifting to alternatives like R-32 and R-454B, which are both GWP-based, with GWP values of 500 and 650 and 650, respectively. These brand new A2L refrigerants have been designed to deliver high-performance with less environmental impact.

Understanding Global Warming Potential

The GWP value is a measure used to compare the ability to trap heat for different gases over a time period of 100 years. The lower GWP, the lower heat is absorbed by the atmosphere by refrigerants during its entire life cycle which includes production, transportation, use and disposal. When switching to refrigerants with low-GWP in the HVAC industry is aiming to decrease its greenhouse gas emissions, which currently accounts for about 7.8% of global emissions.

The Cost Implications

The cost of HVAC systems 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 between 20 and 30%. The increase could be due to various reasons:

1. New technology The switch to A2L refrigeration calls for rethinking the HVAC system with new components and security measures.

2. Manufacturing adjustments: To comply with rules, factories need to modify their production processes and invest in new technology. This will increase the cost of production.

3. Supply Chain Disruptions to Supply Chain The disruption could result in temporary shortages and higher prices for materials and parts.

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

For homeowners, this could mean paying between $6,000 and $8,000 for a new HVAC system with installation. Some manufacturers might offer rebates to help reduce the cost of these upgrades.

Transition out of the current systems

While the new regulations primarily affect the new HVAC units, they will affect existing HVAC systems. Production of R-410A and other refrigerants with high-GWP will be drastically reduced, leading to a decrease in availability and a rise in prices for these older refrigerants.

This phase-out creates a challenge for homeowners with old HVAC units. As the supply of R-410A dwindles, the maintenance and repair of the systems will become more expensive. The increasing costs for servicing may make a complete system replacement more cost-effective for homeowners with older systems.

Technological Advancements
