921951 — 2.0 Ton Coil (24,000 BTU)

921952 — 2.5 Ton Coil (30,000 BTU) (This Product)

921953 — 3.0 Ton Coil (36,000 BTU)

921954 - 5.0 Ton Coil (48,000 BTU)

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
