Be aware, if you have high/vaulted ceilings I would recommend ceiling fans.
From the old principle of "hot air rises" and "cold air falls" during the summer your A/C units may perform efficiently however during the winter months when the units are producing warm air because of the above principle your units will be heating the space above your head instead of at floor level no mater if you have the internal fan/blower unit going at full speed. The ceiling fans would direct the "Hot" air to where it should be at floor level
I would also recomend that if you have an intruder alarm your A/C units may be able to be interlocked via a no-volt contact (normally available in most reputable alarm systems) so that when you "arm" the intruder alarm when leaving the premises the Power is switched off to the A/C units.Perhaps the installer could advise you if this is possible
I believe there is a unit available on the market that can be bought and installed in your premises for not a lot of money this was discussed in a previous thread and I can't remember when
I don't own a property but regularily long term rent during the Spannish winter months therefore am liable to pay the utility bills and leaving the Heating/Cooling system on when not in the premises can cost a fortune
Hope these points help
Regards
Billy
