Air conditioners perform two basic functions: Heat removal and moisture removal. Although it might seem that heat removal is the only important function of the two, moisture removal is also paramount to comfort during the hot months.

Refrigeration air conditioning equipment normally reduces the humidity of the air processed by the system.

How?

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 relative humidity.

Dry air is more comfortable in the summer. In fact, the lower the humidity level of your home in 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.

Oversized air-conditioning systems are a problem in Dallas-Fort Worth because they do not remove enough humidity from your home in the summer.

There is a second problem, though. An oversized unit repeatedly cycles off and on. When your unit is cycling, you are not running your system at its peak efficiency and you are actually using more energy to operate the system.
