2005 equinox takes a lot of antifreeze, nothing on the ground.

Might be leaking when engine is running, put it in park and let it run for a while and check for leaks. Turn heater on and check heater box condensation drain isn't dripping coolant (a sign of a leaky heater core). Check radiator cap/reservoir cap, they may be allowing coolant to escape via overflow tube to ground - those caps should be replaced every couple years anyhow. Keep an eye on temp gauge, is it running above normal? Worst case scenario losing coolant out tailpipe due to bad head gasket.
