1. New Technology The transition to A2L refrigerants means that HVAC systems using new components and safety features.

2. Manufacturing adjustments To meet rules, factories need to modify their production processes and invest in the latest technologies. This increases the cost of production.

3. Supply Chain disruptions The change could result in temporary shortages and higher costs for materials and components.

4. Training and certification: HVAC technicians will need additional training to handle the new refrigerants with care, potentially leading to higher cost of labor.

This could cost homeowners between $6,000 and $8,000 for installation for a new HVAC system. Certain manufacturers offer rebates that will help offset the increase in cost.

The Phase-Out of Current Systems

The new rules will not only affect the new HVAC units, however, existing ones too. R-410A production as well as that of other high-GWP gases will be significantly reduced. This will result in an increase in supply and also a higher prices for these older refrigerants.

The phase-out poses a problem for homeowners who have older HVAC systems. Repair and maintenance for the systems will become more expensive as the availability of R-410A diminishes. Homeowners who have systems more than 10 years old might find that the rising costs of maintenance makes the replacement of a complete system more affordable in the long run.

Technological Advancements

The shift to refrigerants with low GWP is not just about changing one chemical for another. The HVAC industry is growing significantly due to this.

Enhanced Safety Features

A2L refrigerants are more eco-friendly they are also flammable. To address this, new HVAC systems will be equipped with modern safety features.
