In Central Texas we do not need humidifiers, In most cases a dehumidifier is more appropriate (and recommended) to remove more humidity/lower the enthalpy. Moisture in the air adds to the latent heat load of the home. If we lower the humidity, it will make the air more comfortable at higher temperatures. That means you could be more comfortable at 75° with a 40% humidity, than 72° with a 50% humidity inside. The higher set points would save you more energy and equipment run time.
