4. Training and Certification: HVAC Technicians will require additional training to handle the new refrigerants, which could result in increased labor costs.

For homeowners it could be between $6,000 and $8,000 to purchase an HVAC system that is new and requires installation. Some HVAC manufacturers offer rebates which could help offset the higher cost.

Phase-out of Current Systems

While the new regulations primarily affect new HVAC systems, they may affect existing HVAC systems. R-410A production and that of other high-GWP gases will be significantly reduced. This will lead to an increase in the supply and an increase in cost for the older refrigerants.

The demise of R-410A poses a problem for homeowners who are using older HVAC systems. As the supply of R-410A diminishes, servicing and repairs to these systems will become increasingly expensive. Homeowners who have systems more than 10 years old may find that the rising costs of maintenance makes replacing the entire system affordable in the long run.
