Nordyne 921952 Indoor Coil

The Nordyne 921952 Indoor Coil is a professional-grade 4-ton evaporator coil designed for high-performance residential and light commercial cooling applications. This uncased A-coil features a robust O2HS tube and fin architecture, utilizing all-aluminum construction for both fins and piping to provide superior thermal conductivity and resistance to common environmental formicary corrosion. Engineered as a Replacement Coil HS02 for high-SEER systems, it comes factory-equipped with a .067 orifice to ensure precise refrigerant metering and optimal evaporator pressure regulation. Its 48,000 BTU cooling capacity makes it a critical component for restoring system efficiency in 10 to 14 SEER units. Designed for maximum field flexibility, it is fully compatible with both R-22 and R-410A refrigerants, allowing for seamless integration into legacy retrofits or modern high-efficiency setups. This Nortek Global HVAC OEM part meets rigorous AHRI indoor coil standards and is UL Listed for safety and reliability.

Key Benefits for Technicians

• Precise Refrigerant Flow: Includes a factory-installed .067 orifice for accurate expansion across 4-ton HVAC systems.
• Multi-Refrigerant Support: Verified compatibility with R-410A and R-22, reducing inventory complexity for replacement projects.
• Flexible Installation: The uncased coil design allows for easier slide-in replacement in existing plenums without the need for additional cabinet modifications.
• OEM Standards: Manufactured by Nortek Global HVAC to ensure direct fitment and performance matching with Intertherm, Miller, and Maytag air handlers.

Common Questions

Is the Nordyne 921952 compatible with 14 SEER equipment?
Yes, this replacement indoor coil is engineered for high SEER systems, including 13 and 14 SEER mobile home and residential air handlers, provided the tonnage matches.

Does this unit include a TXV?
No, this model features a .067 fixed orifice. If your specific high-efficiency application requires a thermostatic expansion valve, it must be field-installed separately.

Can I use this for a 3.5-ton system?
This is a 48,000 BTU (4-ton) rated coil. While some matchups may allow for slight tonnage deviations, always verify your system's AHRI certificate to ensure proper pressure balancing and oil return.
