Keep your Lennox CR22-41-TXV-2 evaporator coil system performing at its best with genuine OEM replacement parts from Repair Clinic. The CR22-41-TXV-2 is a Lennox CR-series cased evaporator coil with a factory-installed TXV for approximately three-and-a-half-ton R-410A applications. The coil is typically installed above a furnace in an upflow application or below it in a downflow application, and the N-coil or A-coil geometry allows the assembly to be slid forward out of the cabinet for cleaning and service. Repair Clinic stocks genuine Lennox OEM parts for the CR22-41-TXV-2 including the Lennox drain pan parts, Lennox TXV valve parts, and coil insulation.

CR22-41-TXV-2: Lennox CR-Series Three-and-a-Half-Ton Cased Evaporator Coil with Factory TXV
The Lennox CR22-41-TXV-2 is specifically designated for R-410A refrigerant systems, and the factory-installed TXV is preset for R-410A operating conditions. This coil must be paired with an R-410A outdoor unit and must never be installed on an R-22 system. TXV replacement requires EPA Section 608 refrigerant handling certification because the valve is inside the refrigerant circuit.
Most Replaced Parts on the Lennox CR22-41-TXV-2
Drain Pan for the Lennox CR22-41-TXV-2
The condensate drain pan collects moisture from the coil surface during cooling operation. A drain pan that overflows continuously has a clogged condensate drain outlet rather than a cracked pan. Clear the drain line before replacing the pan to confirm the pan itself is cracked rather than simply overflowing from a downstream blockage.
TXV for the CR22-41-TXV-2
The factory-installed TXV meters refrigerant flow into the coil based on superheat at the suction service valve. A TXV stuck fully open causes a flooded coil and liquid refrigerant slugging the compressor. A TXV stuck closed causes a starved coil with no cooling capacity. TXV replacement requires EPA Section 608 refrigerant handling certification.
Coil Insulation
The coil insulation wraps refrigerant tubing connections and cabinet panels to prevent ambient moisture from condensing on cold surfaces outside the coil cabinet during cooling operation. Deteriorated or missing insulation causes moisture to accumulate on the exterior of the coil cabinet.
Distributor Assembly for the CR22-41-TXV-2
The distributor distributes refrigerant flow evenly from the TXV into the multiple parallel circuits of the coil. An uneven refrigerant distribution from a damaged distributor causes some coil circuits to operate below capacity while others operate at excess capacity.

Lennox CR22-41-TXV-2 Evaporator Coil Parts FAQ
What is the Lennox CR22-41-TXV-2 and what does the model number decode to?
The Lennox CR22-41-TXV-2 is a cased evaporator coil assembly. CR22 identifies the Lennox CR-series cased coil product line, 41 identifies the coil capacity in hundreds of BTU corresponding to approximately three-and-a-half-ton capacity, TXV indicates the coil includes a factory-installed thermostatic expansion valve, and 2 identifies the revision within the product series.
What refrigerant does the Lennox CR22-41-TXV-2 use?
The CR22-41-TXV-2 uses R-410A Puron refrigerant. Confirm the refrigerant type of the matched outdoor unit from its data plate before any refrigerant service. The TXV on this coil is preset for R-410A and must not be used with R-22 equipment.
Why is my Lennox CR22-41-TXV-2 coil icing up?
Coil icing is most commonly caused by a low refrigerant charge in the outdoor unit, restricted airflow from a clogged filter or dirty coil fins, or a blower motor not delivering adequate airflow across the coil surface. Replace the air filter before inspecting airflow and refrigerant charge.
Does the Lennox CR22-41-TXV-2 come with a factory-installed TXV?
Yes. The TXV in the model name indicates this coil includes a factory-installed thermostatic expansion valve preset for R-410A systems. The TXV is inside the refrigerant circuit and cannot be replaced without recovering the refrigerant charge first. TXV replacement requires EPA Section 608 certification.
