Mini Splits for Mother-in-Law Suites and Multigenerational Living
Updated September 2026
Mother-in-law suites and multigenerational living spaces require efficient and reliable heating and cooling solutions. Ductless mini splits are a popular choice for these areas as they provide zoned cooling and heating, are energy efficient, and do not require ductwork. In Central Texas, where summers are hot and winters are mild, mini splits are a suitable option as they can handle both cooling and heating needs without the need for a furnace.Benefits of Mini Splits for Mother-in-Law Suites
