A vs N

[mmartinez]

I am installing a new Carrier A/C to replace a broken ComfortMaker a/c. I am down to selcting a coil: A vs N. From the discussion above, I still don't see why I should go with one vs the other ? I can go with either but I would like a technical/engineering explanation why one or the other is better.

The A-Coil is taller than the N-coil, so if you have more of a space constraint a N-Coil might be a better fit. The S-coil (Slab) is even smaller.

The A-Coil has slightly better cooling and lower static pressure loss... so if you can fit an A-Coil then great, but the performance differences are not much so it really comes down to space constraint and cost.
