Our house's outlet temperature at the floor register is about 14C/57F on a day when the outside temperature is 30C/86F. But I feel the register temperature is a bit too warm...

How many degrees should home air conditioning be at the vents?

measuring how effective your air conditioning is at the supply
air diffusers will not be an accurate gauge of it's function. The
temperature measurements should be taken just above and below the
evaporator coil. The return temperature (below the coil, if not
possible, then upstream of the blower) should be 15-20 degrees
Fahrenheit higher then the supply temperature. Keep in mind that
this temperature difference is affected by the blower speed as much
as it is by the function of the air conditioning system. Therefore
it can only indicate that something is not functioning correctly,
but will not troubleshoot which part of the system is
malfunctioning.
