All new residential air conditioners, heat pumps and other appliances must utilize refrigerants that have Global Warming Potential (GWP) below 700 on January 1st, 2025. This move is part of an overall attempt to decrease the amount of hydrofluorocarbons (HFCs) that are greenhouse gases that have a high GWP.

The current industry standard, R-410A, which has been widely utilized due to its safety and efficiency, will be phased out. Manufacturers are now turning to other refrigerants, such as R-32 or R-454B with GWP values ranging from 500 to 650. These new refrigerants are referred to as A2L refrigerants, have been designed to provide high performance and significantly reduce environmental impact.

Understanding Global Warming Potential

GWP is a metric used to compare the ability to trap heat for different gases over a time period of 100 years. The lower the value of GWP, the less heat is absorbed into the atmosphere by refrigerants during its entire life cycle, including production, transport, use and removal. HVAC companies are trying at reducing their contribution to global greenhouse gas emissions by switching to low-GWP refrigerants. These gases currently account for 7.8 percent of the total emissions.

The Cost Implications

The price of HVAC units will increase immediately and noticeably due to these new regulations. According to industry experts, the cost of air conditioning units could increase by between 20 and 30%. This increase is attributed to several reasons:

2. Manufacturing Improvements Factories must revamp their processes and invest in the latest technologies to meet the rules, which will increase production costs.

3. Supply Chain disruptions This change may result in temporary shortages of materials and components as well as higher costs.

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

The homeowners could pay between $6,000-$8,000 when they install for a brand new HVAC unit. Some manufacturers offer rebates that will help offset the increase in cost.

The Phase-Out of Current Systems

The new regulations will not just affect the new HVAC units, however, existing ones too. The production of R-410A and other refrigerants with high-GWP will be significantly decreased, resulting in less availability and a rise in prices for these older refrigerants.

The phase-out poses a problem for homeowners who have older HVAC systems. Maintenance and repair of these systems will become more expensive as the availability of R-410A decreases. homeowners with systems that are more than 10 years old might find that the rising cost of servicing makes the replacement of a complete system more economical in the long run.

Technological Advancements
