At what point is it damaging the AC? below 100V or is that 106 - 109 an issue?
Motor is rated 115v +- 10% so 103.5 is the lowest but that is right at the motor. I would consider shutting one down if you are dipping to 105.
Consider a powermaster booster if you will be doing this frequently.
Of course, in reality it's not a hard and fast number.
Run if for a weekend at 105V and you will probably never "see" an issue to it. Do it regualarly and instead of a 15-20yr life, you may only get 5-8yrs out of the AC units.
Of course, I'm talking in gereraltites. Predicting the exact life based on your usage is near impossilbe. The point being, unless the voltage goes way low, it isn't likely that the AC will run for an hour and then the compressor dies suddenly. It's more of an accumulation of damage.
I don't like when the voltage gets much below 107-108V.
A suggestion: If you don't use the sleeping areas during the day, do you really need them cooled? We only have a single AC but when it gets into the 90's and above, we often close off the sleeping area and just cool the main living area during the day. At night, with the sun down, you need far less cooling, so we open the ducts to cool the sleeping area.
