Friedrich TCFY3621STANMC Cased Evaporator Coil 2.5-3 Ton R454B

Product Description

The FRIEDRICH TCFY3621STANMC is a cased evaporator coil designed for residential and light commercial split-system air conditioning and heat pump applications. Rated at 36,000 BTU/h and sized for 2.5 to 3 nominal tons, it ships with a thermostatic expansion valve (TXV) already integrated, eliminating the need for a field-supplied metering device. The 21-inch cabinet width fits a range of air handler and furnace configurations. Compatible with R454B refrigerant, this coil aligns with current low-global-warming-potential refrigerant requirements. Installation is handled by licensed HVAC technicians.

This coil is suited for multi-position installation, meaning it can be configured for upflow, downflow, or horizontal airflow depending on the equipment and jobsite layout. The cased design provides a self-contained cabinet that mounts directly to a matched air handler or furnace, supporting a clean, code-ready installation. Its 36,000 BTU/h capacity covers typical residential applications such as single-family homes or small commercial spaces requiring 2.5 to 3 tons of cooling. The integrated TXV meters refrigerant flow to the coil automatically, supporting consistent performance across varying load conditions.

Installation Notes

Installation must be performed by a licensed HVAC technician holding an EPA Section 608 certification for handling refrigerants. Shut down and de-energize the entire system before connecting or disconnecting refrigerant lines. Follow local mechanical codes and manufacturer guidelines for coil orientation, drain pan connection, and condensate line routing. Do not operate the system without verifying refrigerant charge and system pressures are within the equipment manufacturer's specified range for R454B.
