You have nominal 120V on each hot leg coming into your house. Use both legs and you get 240, like for dryers and ovens.
110, 220 has never been my experience. The actual voltage I see in the last couple places I've lived is 123-126V per leg. It varies, as the power company matches generating output with a fluctuating demand.
