Questions homeowners ask.
Is a mini-split a good fit for a room without ductwork?
Often, yes. Additions, garages, basements, attics, and older homes can be good candidates when the layout and electrical requirements work.
Can you install more than one indoor unit?
Yes. Multi-zone ductless systems can serve several rooms with separate indoor units connected to outdoor equipment.
