Heat Pumps & Mini-Splits

What Is Ductless Mini-Split?

Definition

A ductless mini-split is a heat pump that conditions a room or zone directly through a wall- or ceiling-mounted indoor unit connected by a small refrigerant line to an outdoor compressor — no ductwork required. It's the standard fix for additions, garage conversions, and homes heated by inefficient electric baseboard or wall heaters.

Why it matters for your home

Energy Trust of Oregon pays $800 (or $1,800 income-qualified/rental) toward a qualifying mini-split that replaces electric-resistance baseboard or wall heat in your main living space — a direct, sourced dollar figure worth checking before assuming ductless is out of budget.

What to do about it

If any room in your home relies on electric baseboard or wall heaters, ask specifically about the mini-split rebate — it applies to exactly that replacement scenario.

Money term — the details

Does a mini-split need ductwork?
No — that's the point of the design. Refrigerant lines (not air ducts) run between the compact outdoor compressor and one or more indoor heads, which is why mini-splits work well in additions, garages, and homes with no existing ducts.
What's required to qualify for the Energy Trust mini-split rebate?
An HSPF2 8.10+ system installed by an enrolled trade ally, replacing electric-resistance heat (baseboard/wall heaters) as the primary heat source in the main living space — see the rebates & incentives guide for the current figures.
