I’m wondering whether those that follow Rav Moshe ZT’L on an issue he’s a Daas Yochid when he’s mattir, such as permitting shaving, also follow Rav Moshe when he’s a Daas Yochid and he assurs, such as prohibiting having an air conditioner turn on during Shabbos with a timer.
Surely those that shave will never permit an air conditioner to be set to go on or off during Shabbos.
