We are leaving tomorrow afternoon headed for the lake. However, Friday I have to work and DW DD DS are all coming into town for the day for school activities etc. Is it ok to leave the ac running in my absence? It will probably run for 8 hours give or take. Its going to be 100 degrees Friday with no shade. I am concerned about keeping it comfortable as well as helping the fridge keep up (plan on running it on propane). Is there anything wrong with leaving the ac running? If we were staying all day it would run.
