Our thermostat is programmed to run the fan a minute of 20 minutes over the course of an hour, regardless of the unit calling for heat/AC
Helps help the air fresh during those seasons when the house self.maintains temp.
That is a good idea.
I have personally struggled trying to keep all the rooms in a 2 story house in the same comfort zone, temperature and humidity wise.
I have also “been forced to discover”
that air mover fan motors need yearly lubrication if they have sleeve bearings
and that the original USA made electrical contactor and its associated control relay for the motor can last 20+ years,
but the Chinese replacements can fail in months.
I would like to figure out an inexpensive way for the always-on fans of HEPA filter units to equalize
temperatures, freshness,
and the latest medical “buzzword” - 2.5 micrometer air pollution particles
between upstairs and downstairs rooms
to relieve some of the stop/starts on the expensive blower motor and its “gotta use a puller” squirrel cage fan.
I am leaning toward installing duct pipes between stacked upstairs/downstairs bathrooms,
or just selling this house and living on the beach in a one story house in Florida where hurricanes surpass all ventilation levels.
