R454B & A2L HVAC OEM Solutions

1. R454B as a New HVAC Product Platform

North American residential and light-commercial HVAC products are moving toward lower-GWP refrigerant technologies.

R454B, as an A2L refrigerant, is being applied to a new generation of:

• Split Heat Pump Systems
• Central Air-Conditioning Systems
• Ducted HVAC Systems
• Multi-Position Air Handlers
• Packaged HVAC Equipment
• Rooftop HVAC Systems

For OEM customers, this means product development must consider more than refrigerant selection alone.

Equipment design, A2L safety, system matching, installation requirements, certification and destination-market compliance all become part of the final HVAC product solution.

2. R454B Heat Pump + Air Handler Systems

For North American residential and light-commercial applications, YUJU can provide R454B HVAC system configurations based on project capacity, efficiency, electrical and installation requirements.

Typical North American capacities can include:

Final system selection can also consider:

• Cooling and Heating Capacity
• SEER2 / EER2 / HSPF2
• Airflow / CFM
• External Static Pressure
• Multi-Position Installation
• 208–230V / 1Ph / 60Hz Applications
• Thermostat Compatibility
• Auxiliary Electric Heat Options
• Refrigerant Piping
• Installation Accessories

3. AHRI Certified System Combinations

For North American split HVAC systems, the relationship between the outdoor unit and the indoor air handler is an important part of certified system performance.

The matched system can affect:

• Cooling Capacity
• Heating Capacity
• SEER2
• EER2
• HSPF2
• System Certification

YUJU can provide applicable Certified Model Combination and related AHRI information according to the selected product configuration.

Where applicable, customers can independently verify the provided model combination and AHRI reference information through the official AHRI directory.

4. A2L Safety & Product Compliance

R454B is classified as an A2L refrigerant. Therefore, the HVAC system must consider the safety requirements applicable to A2L equipment.

Depending on the specific product and application, these requirements may involve:

• UL 60335-2-40
• ETL / UL Product Safety Listing
• A2L-Compatible Components
• Refrigerant Safety Design
• Leak Detection or Mitigation Where Applicable
• Electrical Safety
• Product Labeling
• Installation Requirements
• Technical Documentation

YUJU can provide applicable product safety and certification documentation according to the selected HVAC system and destination-market requirements.

5. DOE / CCMS & U.S. Market Compliance

Energy-efficiency compliance is another important part of HVAC OEM programs for the U.S. market.

Depending on the product category and project, requirements may involve:

• DOE Basic Model Information
• Applicable Energy-Efficiency Data
• CCMS Documentation
• Private-Label Product Information
• Brand and Model Registration Support

6. Private Label & PBM Support

Many North American HVAC customers want to develop and sell products under their own brands.

YUJU supports private-label HVAC programs including:

• Customer Brand
• Private Label
• PBM Project Support Where Applicable
• Customized Nameplates
• Product Labels
• Customized Packaging
• Model Naming
• Technical Documentation
• Product Manuals
• Certification Documentation Coordination

7. OEM Is More Than Adding a Logo

A professional HVAC OEM program usually involves much more than replacing a brand name.

Depending on the customer's market, YUJU can support:

• Capacity Configuration
• Voltage / Frequency
• R454B / A2L Refrigerant Platform
• Heat Pump Configuration
• Air Handler Matching
• Electric Heater Options
• Controls
• Thermostat Compatibility
• Airflow Configuration
• Cabinet Requirements
• Corrosion Protection Where Required
• Nameplates
• Packaging
• Technical Documentation
• Certification Support

8. Start a Product Line with the First Container

Customers developing a new HVAC brand do not always need to launch a large number of product models in the first order.

A practical product line can begin with core North American capacities such as:

Depending on the selected products, the commercial plan can evaluate:

• MOQ
• Complete Sets / 40'HQ
• Mixed Container Loading
• Capacity Mix
• Production Lead Time
• OEM Packaging
• Future Product Expansion

This can allow importers and distributors to test different capacities in the local market while gradually developing a broader HVAC product portfolio.

10. Beyond R454B Split HVAC

R454B is an important part of the current North American low-GWP HVAC transition, but YUJU's OEM capability is not limited to one refrigerant or one equipment format.

Depending on the application, YUJU can also support:

• Ducted Heat Pumps
• Split Heat Pump Systems
• Air Handlers
• Packaged HVAC
• Rooftop Units
• Commercial HVAC
• Customized Air Handling
• Fresh-Air Systems
• Smart HVAC Controls

Final product configuration should always be determined according to the destination market, product category and actual application requirements.

11. Building a Long-Term HVAC Product Portfolio

For importers, distributors and private brands, the first R454B OEM project can also become the starting point for a broader HVAC product strategy.

YUJU supports customers who want to move from individual HVAC products toward a broader product portfolio with engineering, controls and environmental solutions.

12. Start Your R454B HVAC OEM Project

If you are planning an R454B HVAC product line for the United States or North American market, you can provide YUJU with:

• Required Tonnage / BTU
• Heat Pump or AC Requirement
• Voltage / Phase / Frequency
• Destination Market
• Required Efficiency
• Required Certification
• Brand / Private Label Requirements
• Initial Order Quantity
