What is a ductless mini split?
A ductless mini split AC system is a type of air conditioning and heating solution that does not use traditional ductwork. Instead, it connects an outdoor compressor to one or more indoor air handler units through small refrigerant lines. Each indoor unit can control the temperature of its zone, offering custom comfort in different rooms.
Benefits include:
Precise temperature control in each room or "zone"
Flexible installation without major remodeling
Quiet operation and improved energy efficiency
Better indoor air quality since no dust-prone ducts are required
Ductless air conditioner cost by size
The total cost increases with the system’s BTU size and the number of indoor air handlers. A standard 1- to 2-ton mini split system (12,000 to 24,000 BTUs) costs $3,500 to $8,000 with materials and labor.
The table below shows average installed costs for mini-splits from small half-ton units to substantial 5-ton packages.
| Unit size (BTUs / tons) | Average installed cost |
|---|---|
| 6,000 (0.5 ton) | $2,500 – $3,500 |
| 9,000 (0.75 ton) | $3,000 – $4,200 |
| 12,000 (1 ton) | $3,500 – $5,000 |
| 18,000 (1.5 ton) | $4,500 – $6,500 |
| 24,000 (2 ton) | $6,000 – $8,000 |
| 30,000 (2.5 ton) | $7,000 – $9,500 |
| 36,000 (3 ton) | $8,000 – $11,000 |
| 42,000 (3.5 ton) | $10,000 – $13,000 |
| 48,000 (4 ton) | $12,000 – $15,000 |
| 60,000 (5 ton) | $15,000 – $18,000 |
Most installation quotes include:
Outdoor compressor/condenser
One or more indoor air handlers
Labor, basic electrical connections, and brackets/pads
Refrigerant line and basic system testing
Standard line set length (about 15 feet) with higher costs for longer runs
Mini split AC cost by style
The indoor unit style affects both the installation cost and how your ductless mini split fits into your home. Wall-mounted units are the most common because they are cost-effective, simple to install, and suit most spaces. Other options may have higher costs for added labor, materials, or special mounting.
The table below shows pricing for each style, including professional installation.
| Unit style | Average installed cost (single-zone system) |
|---|---|
| Wall-mounted | $2,500 – $5,000 |
| Ceiling cassette | $3,500 – $6,000 |
| Floor-mounted | $3,000 – $5,000 |
| Concealed ducted | $4,000 – $7,500 |
Wall-mounted
Wall-mounted units are installed high on the wall and cost $2,500 to $5,000 per zone. This is the most popular and cost-effective choice for mini split systems. Their elevated placement helps distribute cool air evenly and efficiently throughout the room, making them a strong option for both small and large spaces.
Floor-mounted
Floor-mounted units are installed low on the wall, just above the floor, and cost $3,000 to $5,000 per zone. These units work well in rooms with limited upper wall space, large windows, or sloped ceilings. Their low position delivers comfort right where you need it and makes them easy to access for cleaning.
Ceiling cassette
Ceiling cassette units are mounted inside the ceiling and cost $3,500 to $6,000 per zone. This style suits larger or open rooms and offers 360-degree air distribution for even cooling. Installation is more complex, but the discrete look and better coverage make them appealing for open floor plans and shared living areas.
Concealed duct mini split
Concealed duct units are installed in ceilings or attics and cost $4,000 to $7,500 per zone. These units stay hidden from view and use short ducts to cool multiple nearby rooms. They are a practical solution for homeowners who want a nearly invisible system and flexible climate control across several spaces.
Ductless mini split cost factors
Several factors influence your total installation cost:
System size and BTU capacity: Larger units with higher BTU ratings cost more but are needed for larger or open spaces.
Number of zones: Multi-zone systems cost more than single-zone setups. Each additional indoor unit increases both equipment and labor costs.
Indoor unit style: Wall-mounted units have the lowest cost. Ceiling cassette, floor-mounted, and concealed ducted units require added labor or materials and have higher prices per zone.
SEER rating and brand: High-efficiency systems and premium brands cost more up front but can lower energy bills and may qualify for rebates.
Installation complexity and labor: Long line runs, hard-to-reach locations, and extra wall or electrical work increase the overall labor cost to install a ductless mini split system.
Permits, upgrades, and added features: Electrical upgrades, permits, and features like smart controls or better filtration add to the cost.
Mini split air conditioner cost by brand
Ductless mini-split AC costs can vary significantly depending on the brand you choose. Higher-end brands often cost more but may deliver improved performance, longer warranties, or better rebate opportunities.

|---|---|
| Mitsubishi / Trane | $1,400 – $4,800 |
| Fujitsu / Rheem | $1,300 – $4,700 |
