Refrigeration air conditioning
equipment normally reduces the humidity of the air processed by the
As air cools, it loses its ability to
hold moisture. Your air-conditioning system works like the dew you see on
the grass on a summer morning or the way an ice-cold drink condenses water
on the outside of a glass.
The evaporator coil is below the dew
point. It removes water vapor from the processed air and sends that water
to a drain. By removing water vapor from the cooled space, it lowers the

summer, the more comfortable you will feel at a given temperature. A properly
operating and sized air conditioning unit should also lower the
humidity in your home.
air-conditioning systems are a problem in Dallas-Fort Worth because they
do not remove enough humidity from your home in the summer.
