It’s completely dependent on where you live. In Nevada where the winter lows are normally in the 40s°F and summers highs are in the 110s°F I only need to warm my house up 30 degrees to stay comfortable, but I need to cool it by 40 degrees to stay comfortable. During the winter the sun is helping warm my house and during the summer it’s fighting against me. In Minnesota where the lows get down to the teens I have to warm my house up 50 degrees to keep it nice while I would only have to cool it down 20 or 30 degrees in the summer to keep it cool.
