"As far as setting thermostats for variable temps, the truth is that it is of very questionable energy saving value for any type of heating/cooling system. Changing the temperature of a house takes a lot of energy and when you try to raise the temp several degrees all at once in Winter or lower it all at once in Summer, the actual energy balance could go either way." - salaryguru

My good friend that went back to school and got a degree in refrigeration and air conditioning told me that when you heat and cool a house you aren't just heating and cooling the air, you are also heating and cooling the walls and the furniture and glass and TV and beds and lumber and floors and ceilings so that it takes a long time to get everything adjusted so when you mess with the thermostat all it does is keep the heat pump constantly working trying to adjust the temperature of everything in the house.... not just the air. He told me it's better to just set the temperature of the house where you want it and leave the damn thing alone and let it do it's job.

How much money do you save when you have to replace a $3,500 dollar heating and cooling system because you've worn the damn thing out making it work overtime trying to keep all the fixtures and walls and floors and ceilings and furniture in the house to what you've set the thermostat on?
