Couple sits on a couch looking at a laptop and papers together, appears to be reviewing finances or documents at home.

A Bryant ductless mini split installation in Pennsylvania, New Jersey, and Delaware typically costs between $5,000 and $7,000 for a single-zone system and $10,000 to $40,000 for a whole-home multi-zone system, installed. Costs vary by zone count, line-set distance, and electrical work. The federal tax credit expired on December 31, 2025, but New Jersey homeowners can still claim up to $7,500 through the state’s Whole Home Energy Solutions program, and Delaware offers rebates through Energize Delaware.

Is There Still a Federal Tax Credit for Heat Pumps in 2026?

Window AC vs. Mini Split

Mini Split vs. Window Air Conditioner: What Does the Upgrade Cost?

A window air conditioner and a ductless mini split solve the same problem — a room that’s uncomfortable — at very different costs over time.

Window Air ConditionerDuctless Mini Split
Upfront cost$150 – $400 per unit$5,000 – $7,000 per zone, installed
Running costHigher — lower efficiency, single-room onlyLower — inverter technology, zoned operation
Typical lifespan8 – 10 years15 – 20 years
ComfortOne room, loud operation, blocks the windowWhole-home zoning available, quiet, efficient operation

A window unit costs less to buy, but a mini split costs less to run and lasts roughly twice as long — and it can cover more than one room.

The Basics

How Ductless Mini Splits Work

A ductless mini split is a heating and cooling system that uses an outdoor compressor connected to one or more indoor air handlers, requiring no ductwork. Refrigerant lines run through a small opening in an exterior wall, and each indoor unit heats or cools the room it’s mounted in independently.

Single-Zone vs. Multi-Zone Systems

A single-zone system pairs one outdoor unit with one indoor unit — the right fit for one problem room, a garage, a sunroom, or an addition. A multi-zone system pairs one outdoor unit with multiple indoor units, each independently controlled, and is sized for a full floor or a whole home.
