Demand varies with the outdoor weather. As the weather becomes more extreme, you can expect your HVAC system demand to increase. Your use of your home can also cause demand to change. For example, having extra guests visiting could increase cooling or heating demand depending on your setting. Alternatively, going on vacation could reduce demand if you set your system to Away mode or if you are using Smart Away.
