2. Manufacturing adjustments In order to comply with the regulations, factories have to retool their production processes and invest in modern technologies. This increases the cost of production.

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

4. Training and Certification: HVAC Technicians will require additional training to handle the new refrigerants, which could mean more expensive labor costs.

For homeowners, this could mean paying between $6,000 and $8,000 for the new HVAC system and installation. Some HVAC manufacturers offer rebates which could help offset the higher costs.

The Phase-Out of Current Systems

While the new regulations mostly affect the new HVAC units, they may affect existing HVAC systems. R-410A production as well as that of other high-GWP gases will be drastically reduced. This will lead to a reduction in supply, and also a higher prices for the older refrigerants.

This phase-out presents a dilemma for homeowners with old HVAC units. As the supply of R-410A diminishes, the maintenance and repair of the systems will become more costly. The increased cost of servicing may make a complete system replacement more cost-effective for homeowners who have older systems.
