921951 Nordyne Evap Coil Tube And Fin R22 / R410A 2 Ton 

Normal Stock Item 

Model: 921951 Type: Tube‑and‑Fin Evaporator Coil Tonnage: 2 Ton (24,000 BTU) Refrigerant: R22 / R410A Configuration: Uncased coil assembly Typical Applications:

• Intertherm / Miller mobile home systems

• Nordyne split systems

• R22 → R410A upgrade replacements

📐 Functional Notes

• Tube‑and‑fin coils are older‑style Nordyne designs used heavily in manufactured housing.

• Compatible with both refrigerants because the coil construction itself is refrigerant‑agnostic; the metering device (piston/TXV) determines refrigerant behavior.

• Often paired with 2‑ton outdoor units and electric furnaces in mobile homes.

Nordyne’s tube‑and‑fin replacement coils follow a predictable pattern:

• 921951 → 2 ton

• 921952 → 2.5 ton

• 921953 → 3 ton

• 921954 → 5 ton ← your part

The jump from 3‑ton to 5‑ton is normal in Nordyne’s older mobile‑home coil catalog — they did not produce a 4‑ton tube‑and‑fin in this series. So with that being said if you have a 4 ton unit use a 5 ton coil it will produce 4 tons of A/C
