Villa will face FC Dallas at the Toyota Stadium on July 23 and Houston Dynamo at the BBVA Compass Stadium on July 26.
Villa boss Paul Lambert said: "It's a good place to go and play football.
"The facilities are really good, the weather will be warm as well and a lot of teams in the Barclays Premier League go to the US now for pre-season, so it will be good for us.
"The Premier League is world-renowned and everywhere you go people know what it's about. They're getting into it now in the US, too, and it's good for us to tap into that interest and to attract new fans to the club."
