4. Training and Certification: HVAC technicians will require additional training in handling the new refrigerants in a safe manner which could result in higher expenses for labor.

This could cost homeowners between $6,000 and $8,000 for installation for a brand new HVAC unit. However, some manufacturers may offer rebates to help reduce the cost of these upgrades.

The Phase-Out of Current Systems

The new rules will not only impact the new HVAC units, however, existing ones too. The production of R-410A and other high-GWP refrigerants will be greatly decreased, resulting in less supply as well as an increase in prices for these older refrigerants.

The gradual elimination of R-410A is a problem for homeowners who are using older HVAC systems. As the availability of R-410A diminishes, the maintenance and repair of these systems will become increasingly expensive. The increasing costs for servicing could make a total system replacement more cost-effective for homeowners who have older systems.
