Does anyone know what the temp difference should be between input and
output (register closest to evaporator) air for a properly sized and
properly functioning residential central a/c?

Does 20F - 25F sound reasonable 10 minutes after turning the unit on
in the morning after being off all night? Note: condenser is in the
shade.

The above temp diff looks good to me, but I wanted to get some other
opinions.

Properly sized or not the Delta T for an A/C doesn't mean all that
much. There are several other readings needed to properly diagnose a
system. The delta T could look good for a system but that doesn't
mean it is properly sized.

It's a good differential, but it is not a conclusive performance test
without confirming the proper air flow.

Without complete operating data, everything would be a WAG.

Kjpro is right, W/O more info it is a WAG!
The normal range depending on airflow CFM through the E-Coil per ton of
coiling, & the percent of Relative Humidity in your home it could range
from say 14-F to 28-F, and yet be within that particular application
condition's tolerances. - udarrell
