Description

The Rheem RH2TY3621STANNJ is a 3 Ton, multi-position air handler from the advanced RH2TY Endeavor™ Line Series. Designed for use with eco-friendly R-454B refrigerant, this model features a factory-installed TXV for precise refrigerant flow control and reliable system performance. Built for vertical upflow, downflow, or horizontal configurations, it delivers flexible installation options. The unit integrates an all-aluminum evaporator coil and a high-efficiency ECM blower motor, engineered for quiet, consistent air delivery. With compatibility across multiple outdoor unit types, it offers outstanding performance for both residential and light commercial systems.

Performance: Equipped with an energy-efficient ECM motor, the RH2TY3621STANNJ supports variable-speed airflow, improving comfort and energy control while helping reduce operational costs. The all-aluminum coil is corrosion-resistant and enhances heat transfer performance. Its factory-installed TXV ensures optimal refrigerant metering, which increases system reliability and consistency across a range of operating conditions. This unit delivers dependable airflow across static pressure ranges, helping optimize SEER2 performance when matched with compatible Rheem outdoor units.

Smart Features: The RH2TY3621STANNJ is compatible with smart HVAC systems and control platforms, enabling integration with advanced thermostats and zoning controls. Its ECM motor can support advanced dehumidification functions, improving comfort and energy efficiency. While the unit doesn’t include native Wi-Fi, it pairs seamlessly with smart-enabled Rheem outdoor condensers or heat pumps and smart thermostats like EcoNet for system-wide remote control and diagnostics.

Comfort & Noise: This model emphasizes low-noise performance, thanks to its ECM blower and insulated cabinet design. It delivers smooth, quiet airflow at consistent temperatures to eliminate hot and cold spots. With airflow capabilities around 1,200 CFM (varies based on configuration), it supports whole-home conditioning with even temperature distribution and improved humidity control. The multiple blower speed taps provide fine-tuned comfort tailored to the space.

Use Case Fit: The RH2TY3621STANNJ is ideal for residential homes, apartments, and multi-family dwellings where R-454B refrigerant compliance and long-term system compatibility are key. Its multi-position design makes it flexible for attic, basement, or closet installation across varying climates, from humid coastal regions to dry inland areas. It's also well-suited for light commercial use in offices and small retail spaces requiring efficient year-round air delivery.

Value & Reliability: Built with Rheem’s industry-leading durability and high-performance components, this air handler offers reliable comfort with minimal maintenance. The all-aluminum coil resists leaks and corrosion, while the powder-coated steel cabinet adds protection in demanding environments. Service access panels and built-in diagnostic features make it easier for contractors to troubleshoot and maintain the unit. Its compatibility with new low-GWP refrigerants ensures regulatory readiness for years to come.

Summary Wrap-Up + Key Features: For D2C buyers seeking high efficiency, and contractors needing proven performance, the RH2TY3621STANNJ delivers value on every front.
