Timothy’s Answer

It's not that humidity negatively affects equipment, it's that humidity removal is an important function of the equipment here in Dallas and especially in South Texas. We get equipment to remove humidity by ensuring proper load calculation so the equipment gets enough runtime, adjusting airflow to a lower setting and adding thermostats with dehumidification terminals that can slow the blower down even more. It's very common to run 450 CFM per ton in the desert and to run 350 CFM per ton airflow in the deep south due to humidity concerns. You also don't see as large of a temperature delta or change between return and supply when the humidity is higher and the delta t normalizes as the humidity percentage comes down.

Timothy recommends the following next steps:

Try running manual j load calculations for your area versus Houston or another part of the deep South to see how equipment sizing changes.
