Mini splits: you’ve seen them in hotels, schools, garages, server rooms and sunrooms. These self-contained units make zoned heating and cooling a breeze, and are a popular choice for home renovations/retrofits, in spaces without existing ductwork, or in spaces that are separated from the main area of your home.
