Mini-split system costs by type
A standard mini-split system costs $1,500 to $8,000 without installation, depending on the type and number of zones. Mini-split systems include an outdoor condenser, indoor air handler(s), and sometimes a wireless remote control.
| System type | Single-zone | Multi-zone |
|---|---|---|
| Indoor wall-mounted | $700 – $4,100 | $1,900 – $7,800 |
| Indoor ceiling cassette | $1,800 – $5,800 | $2,600 – $9,900 |
| Indoor ceiling-suspended | $2,400 – $6,400 | $2,400 – $8,000 |
| Indoor floor-mounted | $1,600 – $3,300 | $2,700 – $8,000 |
| Indoor concealed | $1,700 – $6,000 | $2,600 – $7,900 |
| LG Art Cool Gallery wall mount | $1,300 – $2,100 | $2,900 – $6,400 |
*Not including installation.
Outdoor split AC condensers are placed on a concrete pad or wall-mounted with brackets. Each unit supports up to five indoor air handlers.
Wall-mounted air handlers are installed at least 7' high and are the most popular and least expensive option for homeowners. LG Art Cool Gallery wall mounts hide the air handler behind a picture frame for a stylish look.
Ceiling cassettes are recessed so the grill is flush with the ceiling and distribute air in up to four directions via controllable vents.
Ceiling-suspended units protrude 14" to 16" and work best in rooms with high ceilings or limited wall space.
Floor-mounted air handlers mount at the bottom of the wall at floor-level for rooms that don't have upper wall space available.
Concealed duct air handlers, or slim ducts, mount inside the ceiling and connect multiple vents to provide even cooling in large rooms.
Vertical air handlers connect to pre-existing ductwork and are installed vertically or horizontally. They are self-contained in an insulated metal cabinet for noise reduction and offer a cost-effective alternative to central air.
Single vs. multi-zone mini-split system cost
The average cost to install a single zone mini-split is $1,800 to $6,000 for the system and labor, plus $500 to $2,000 per additional zone for a multi-zone system. One outdoor condenser supports up to five indoor air handlers, or "zones," depending on size.
A single-zone unit cools one room or area with an open floorplan. Enclosed spaces need their own indoor units.
Large open areas may require more than one air handler.
Small bathrooms and hallways do not require their own zones.
| System type | Average cost installed |
|---|---|
| Single-zone system | $2,000 – $6,000 |
| Multi-zone system | $2,500 – $13,000+ |
