Question

What should air temperature be coming out of vents on my air conditioner at home?

Answer 1

Somewhere between 15 and 18 degrees below the temp of the air going into your return air vent.

Answer 2

It will vary with the load and whether or not a problem exists with your a/c.

Rule of thumb is between 16-20 degrees differential between the supply and return air temp.

If you have a 74 return air temp then a 58 supply temp would be acceptable or a 80 return and a 64 supply would be acceptable.
