Note that most US homes actually have 240 V split phase service. Power is typically distributed to a neighborhood at 13.3 kV (but there is a lot of variation), and stepped down by a 240 V center tapped transformer outside your house. The center tap of that transformer is connected to ground and neutral. Normal residential outlets are connected between that neutral and one of the two hot outputs, giving 120 V. Connecting across the two hots instead of across one hot and neutral gives 240 V. Many houses have one or two 240 V outlets. Typically there is one where the builders expected you to put your washer and dryer, to support an electric dryer. Often there is also one in the garage. It's easy for an electrician to add more 240 V circuits4 and, assuming you don't need a new electrical panel, fairly reasonably priced. Googling is claiming typically $250-800.
