New Refrigerant Standards

The new regulations are centered around the requirement of using refrigerants with a lower global warming Potential. All new residential air conditioners or heat pumps as well as other appliances must utilize refrigerants that have a Global Warming Potential (GWP) less than 700 by January 1 2025. It is part of an overall attempt to reduce hydrofluorocarbons which are potent greenhouse gases.

The current industry standard, R-410A, which has been widely utilized due to its effectiveness and safety it will be phased out. In its place, manufacturers are switching to alternative refrigerants such as R-32 and R-454B, which are both GWP-based, with GWP values of approximately 500 and 600 each. These brand new A2L refrigerants have been designed to provide high performance with less 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 period of 100 years. The lower the value of GWP, the lower heat is absorbed by the atmosphere by a refrigerant during its entire life cycle which includes production, transportation use, and removal. HVAC companies are aiming to reduce their contribution to global greenhouse gas emissions by switching to refrigerants with low GWP. These gases are currently responsible for 7.8 percent of the total emissions.

2. Manufacturing Improvements Factories must retool and invest in new technologies to comply with the rules, which will increase production costs.

3. Supply Chain disruptions The transition could lead to temporary shortages of components and materials and higher prices.

4. Training and Certification: HVAC Technicians will need additional training to safely handle the new refrigerants. This could lead to more expensive labor costs.

For homeowners who live in the area, this means paying between $6,000 and $8,000 to purchase an HVAC system that is new and requires installation. Some manufacturers might offer rebates to help reduce the cost of these upgrades.

The phase-out of current systems

The new regulations won't only affect the construction of new HVAC units however, existing ones too. R-410A production as well as that of other gases with high-GWP will drastically decrease. This will lead to a reduction in supply, and a rise in the cost for the older refrigerants.

The gradual elimination of R-410A is problems for homeowners that have older HVAC systems. As the amount of R-410A decreases, the cost of the maintenance and repair of the systems will become more costly. homeowners with systems that are more than 10 years old could be able to see that the costs of maintenance makes replacing the entire system affordable in the long run.
