Frequently asked questions
Can a mini-split heat in a NH winter?
Yes — modern cold-climate heat-pump mini-splits heat efficiently well below freezing.
Do I need ductwork?
No — that's the advantage. Mini-splits mount on the wall and run a small line set to the outdoor unit.
Can you do multiple rooms?
Yes — one outdoor unit can run multiple indoor heads for zoned comfort.
