When does a Task actually start?
public void DoSomething() { Task myTask = DoSomethingAsync(); Task.WaitAll(new[] { myTask }, 2000); } public async Task DoSomethingAsync() { await SomethingElse(); } Does it start immediately when initializing it in Task myTask = DoSomethingAsync(); or does it start when you say to wait for it in Task.WaitAll(new[] { myTask }, 2000); ?

Ideally, a properly operating air conditioner should cycle for roughly 15 to 20 minutes, two to three times per hour. If the temperature inside your home is very high, is much higher than the temperature that your thermostat is set at, or the outside temperature is very high, the run time will increase.
Hot and cold air conditioners can regulate the temperature according to your liking, both in summers and winters. The air conditioner simply reverses its function, allowing the AC to run efficiently during winters, thus throwing warm air in the room.
As a general rule of thumb, wait for the first stretch of 70 degrees + weather to hit the area. This is when you'll turn on your AC for the first time. However, you're not doing so because you necessarily need to cool down your home.
If you're setting your air conditioner in cooling mode, doing so at lower than 21C will normally be regarded as too cold to have much impact and is generally wasteful of electricity.
Calling an async method returns a hot task, a task that has already been started. So there is no actual code necessary to force it to run.
According MSDN (thanks to Stephen Cleary) the Task-based Asynchronous Pattern (TAP) pattern requires returned tasks to be hot. That means that all tasks, except those created with new Task will be hot.
From the referenced article:
Tasks that are created by the public
Taskconstructors are referred to as cold tasks... All other tasks begin their life cycle in a hot state.
