Heat or humidity?

The high end A/C systems have a dehumidify setting. Most people set it around 40-50%. It runs the compressor and blower on low speed to draw out more humidity. Mine is set on 50% and it's 74 inside and it feels cold when you walk in. People would be shocked when I would take a reading with my hand held temp/RH meter and show them. Their T-stat was showing 72 and it's clammy as hell because someone sold them a 5 ton unit on a 1500 sq.ft. house, and they have 80% RH. Bigger is not always better. Older systems can be retrofitted with a thermidistat that would give a setting for RH control.
