In most cases, they do not come with a overflow valve, That is a addon that most companies install when they do the install. They can be purchased from most ac suppliers I recommend the SS-2 or SS-1 safety overflow switch, comes with two wires you can tie into your low voltage wiring to your thermostat.
Hope this helps.
