As we move towards 2025 the heating, ventilating, and air conditioning (HVAC) industry is on the brink of major change. The Environmental Protection Agency is preparing to introduce new regulations that will fundamentally alter the manner in which air conditioners are designed, manufactured and installed, as well as the way they are operated. The new regulations are designed to decreasing the HVAC system's environmental impact. They will have wide-ranging impacts for both installers and manufacturers. Learn more at SmartACSolutions.com

New Refrigerant Standards

The new regulations revolve around the requirement of using refrigerants with a lower global warming Potential. From January 1st, 2025, all new air conditioners for residential use and heat pumps have to use refrigerants that have a GWP lower than 700. It is part of a larger effort to reduce hydrofluorocarbons, which are powerful greenhouse gases.

R-410A is scheduled to be phased out as it's no longer an industry-wide standard. Instead, manufacturers are switching to alternative refrigerants such as R-32 and R-454B, which are both GWP-based, with GWP values of around 500 and 700, respectively. These new refrigerants are referred to as A2L refrigerants, are engineered to maintain high performance while significantly reducing environmental impacts.

Understanding Global Warming Potential

The GWP value is a measure used to compare the ability to trap heat for different gases over a 100-year period. The lower GWP value is, the lower heat a refrigerant traps in the atmosphere during its lifecycle which includes production, transport, use and the disposal. HVAC companies are trying to decrease their contribution to global greenhouse gas emissions by switching to refrigerants with low GWP. These gases currently account for 7.8 percent of the total emissions.

The Cost Implications

The cost of HVAC systems will be increased immediately and clearly as a result of these new regulations. According to industry experts, the cost of air conditioning units could increase by between 20 and 30 percent. The reason for this is various reasons, such as:

  1. New technology: The shift to A2L refrigerants means that HVAC systems, with new components and security features.

  2. Manufacturing Changes: Factories need to revamp their processes and invest in the latest technologies to meet the rules, which will increase the cost of production.

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

  4. Training and certification: HVAC technicians will require additional training in handling the new refrigerants safely and efficiently, which could lead to increased labor costs.

It could cost homeowners anywhere from $6,000 to $8,000 with installation for a brand new HVAC unit. But, certain manufacturers could provide rebates to offset these increased costs.

The Phase-Out of Current Systems

While the new regulations primarily affect the new HVAC units, they could affect existing HVAC units. Production of R-410A and other high-GWP refrigerants will be significantly decreased, resulting in less supply as well as an increase in prices for these older refrigerants.

This phase-out creates a challenge for homeowners with old HVAC units. Maintenance and repair of these systems will become more costly as the supply of R-410A decreases. homeowners with systems that are more than 10 years old may be able to see that the cost of servicing makes replacing the entire system economical in the long run.

Technological Advancements
