Pre-cooling would probably be
Pre-cooling would probably be a good idea. Many years ago I installed a timer thermostat in my home. I set it to warm the house (on cold days!) about 1/2 hour before I got home from work. I learned that I could set the temperature a few degrees lower than when walking into a cold house. Part of the effect was that the pre-warming heated the walls, which then radiated heat into the room. Actually saved me a fair amount of heating cost even though I started heating the house while nobody was home.
