When a ductless mini-split makes sense
A ductless mini-split heats and cools a space without ductwork: an outdoor unit connects to one or more indoor units on the wall or ceiling through a small line set.
Good fits
- Additions, sunrooms and bonus rooms
- Garages and workshops
- Older homes without ductwork
- A room that's never comfortable on the main system
Why people like them
- Each room gets its own temperature control
- No energy lost through ductwork
- Quiet indoor units
- They heat and cool
Things to know
- The indoor unit is visible on the wall or ceiling.
- Each room or zone needs its own indoor unit.
- The washable filters in the indoor unit need cleaning about once a month.
