I use a programmable thermostat in central MD. In terms of recovery, is it easier to heat a house from a set-back temperature, or cool a house from a set-up temperature?

President Bush's new save energy campaign says to set the set-back temperature back 10-15 degrees in the winter!

In the summer, I noticed that it took forever to cool a house from a set-up temperature of even 5 degrees.
