New Refrigerant Standards

In the midst of these new regulations is a requirement to use refrigerants with a lower Global Warming Potential (GWP). Beginning January 1st, 2025 all new air conditioners for residential use and heat pumps will be using refrigerants with GWPs below 700. This is part of a larger effort to reduce hydrofluorocarbons which are greenhouse gases that can be powerful.

The industry standard currently in use, R-410A, which has been widely utilized due to its effectiveness and safety is scheduled to be eliminated. Instead, manufacturers are turning to alternatives such as R-32 and R-454B, which are both GWP-based, with GWP values of around 500 and 650 and 650, respectively. These brand new A2L refrigerants are engineered to offer high-performance and less environmental impact.

Understanding Global Warming Potential

GWP is a metric used to measure the capacity to trap heat of various gases over a period of 100 years. The lower GWP value is, the less heat a refrigerant captures in the atmosphere throughout its lifecycle, which includes production, transportation, use and disposal. HVAC companies are trying at reducing 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 emissions.

The Cost Implications

The price of HVAC units will be increased immediately and clearly because of the new rules. According to industry experts the price of air conditioning units may increase by between 20 and 30%. The reason for this is various factors, including:

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

2. Manufacturing Changes Factories must upgrade their equipment and invest in new technologies to meet the new regulations, and increase production costs.

3. Supply Chain disruptions This change could cause temporary shortages in materials and components and higher costs.

4. Training and certification: HVAC technicians will need additional training to handle the new refrigerants in a safe manner and efficiently, which could lead to increased cost of labor.

The homeowners could pay between $6,000 to $8,000 with installation for a new HVAC unit. Some manufacturers might provide rebates to reduce the cost of these upgrades.

Phase-out of Current Systems

The new regulations will not only affect the new HVAC units, but also existing ones. The production of R-410A and other high-GWP refrigerants will be significantly diminished, which will result in less supply and an increase in prices for these old refrigerants.

The demise of R-410A poses problems for homeowners that have older HVAC systems. As the availability of R-410A decreases, the cost of the maintenance and repair of the system will become more costly. The rising costs of servicing could make a total system replacement more affordable for homeowners with older systems.
