Answer to 1 ) If you turn a hvac system off less than 8 hours. It will cost
you more money to recool the house from a very high temperature to the lower
temperature than just moving up to a higher temperature on the thermostat. If
your going to be gone more than 8 hours move the thermostat to about 85ºF or so
and turn it back down when you get back home. If your going to be gone for 24
hours or more like on vacation. move the thermostat to the highest setting of
about 95ºF and keep the house below 95ºF because refrigerator , Freezers, and
Wine Coolers are not designed to run in temperatures above 95ºF. Most or a lot
of Refrigerator & Freezers will stop working at 100ºF or above. If you read the
installation instruction when you bought the refrigerator or freezer it tells
you to not run the appliance in ambiant above 95ºF. Also do not run it in
Ambiants of below 40ºF.


I never do turn it entirely off, but that is probably a good point about
the effect on other applicances...
