Description

Overview

The Ruud RCFY3621MTANMC is a 3 ton cased evaporator coil — endeavor line cased coil for gas and oil with txv metering device and a2l sensor. It uses a TXV metering device and includes the A2L sensor required for R-454B systems. The coil sits above or below a gas furnace and carries refrigerant from the outdoor condensing unit.

Matching

Coil selection is not simply a matter of tonnage. The specific coil model determines the AHRI-certified efficiency of the whole system — the same condenser and furnace with a different coil produces a different SEER2 rating and a different certificate number. Always match to the AHRI listing for your combination.

Metering Device

A TXV (thermostatic expansion valve) mechanically regulates refrigerant flow and is the standard metering device for single and two-stage systems.

Shipping & Delivery

How do I know which coil matches my system?

Check the AHRI directory for your outdoor unit and furnace combination. The certified listing names the exact coil model — substituting a different coil of the same tonnage changes the rating and invalidates the certificate.

What is the difference between TXV and EXV?

A TXV regulates refrigerant flow mechanically and is standard on single and two-stage systems. An EXV modulates flow electronically for tighter control across varying conditions, and is typically paired with variable speed equipment.

Does this include the A2L sensor?

Yes. The A2L refrigerant sensor is included and is required for R-454B systems.

AHRI-certified matches for RCFY3621MTANMC

The RCFY3621MTANMC appears in 1 AHRI certificates and is certified to pair with the 1 components listed below. Efficiency ratings belong to a matched pairing, not to a single unit, so substituting an uncertified component changes the system's rated performance and voids the certificate that rebate programmes and permit offices ask for.

Buying from a licensed contractor

Kool Air & Heat LLC is a licensed, insured HVAC contractor based in Heber Springs, Arkansas, serving Little Rock, Conway, Cabot, Searcy, Batesville, Jacksonville, Benton, Bryant and communities across the state. Within our service area we can supply and install this equipment, pull the permit, register the manufacturer warranty and commission the system.

Buying equipment and arranging your own installer separately is common and perfectly workable. Be aware that a manufacturer warranty generally requires professional installation and timely registration — confirm your installer will complete both, because an unregistered warranty is discovered at the worst possible moment.

Ordering from outside Arkansas? We ship to all lower 48 states. Line up a licensed installer before the equipment arrives and have them confirm duct sizing and clearances in advance. It is the single most common cause of a delayed installation.
