Three Hypotheses for a Hot, Humid Climate:

  1. Fresh Air delivery is best controlled by a dedicated automatic indoor relative humidity controller, and not by a thermostat or a table lamp timer
  2. Base Airflow Rate is best precisely adjustable, often 15-23 cfm, which is almost imperceptible to allow for Radon to be precisely mitigated with minimal risk of mold.
  3. Fresh Air is best delivered high into a large room where it may be tempered with indoor air to make it unnoticeable, and which makes it easy for the air conditioner to dehumidify it.  Never into a small space like an air handler closet
