Cost of Parts

A ductless mini-split AC system comprises three main parts: an outdoor condensing unit, inside air units, and refrigerant coolant lines to connect everything. They can be bought as a kit, or each part can be purchased individually as needed.

The average prices below are for the parts only and don’t factor in the labor cost for professional HVAC installation, which can cost between $300 and $1,500 alone.

PartCost
Outdoor unit$1,000–$5,500
Indoor unit(s)$400–$1,800
Refrigerant lines$5 per foot
Installation kit$300–$500

Cost by Size

Ductless mini-split installation is determined mainly by the size of the system.

Unit Size (BTUs)Cost
6,000$450–$1,600
9,000$600–$2,300
12,000$700–$3,200
18,000$1,000–$4,200
24,000$1,100–$5,200
30,000$1,600–$5,700
36,000$1,800–$6,000
42,000$3,000–$8,000

The average 12,000 BTU unit will cost about $3,000. Ductless cooling systems cost about 30% more than a new ducted system and nearly twice as much as a standalone window AC, so consider your energy bill while budgeting for the long term.

The advantage of a multi-split or multi-zone system is that it allows you to have different cooling areas in your home. Every outdoor unit can have up to five indoor units attached to them. Most systems come with at least one indoor unit. Additional units can cost between $400 and $1,800. More powerful condensers are needed to run more than five units at a time and can increase costs.

Number of HVAC Zones

When deciding how many rooms you need cooled in your home, you can choose between a single-zone and a multi-zone mini-split system. An HVAC professional can assess each room's square footage to ensure the right fit. More zones lead to higher costs, with single-zone units ranging from $2,000 to $8,800 and five-zone units from $4,800 to $18,000.

Number of ZonesCost
1$2,000–$8,800
2$2,700–$11,100
3$3,400–$13,400
4$4,100–$15,700
5$4,800–$18,000

Brand

Ductless mini-split units offer a range of brand options. Some are reputable and have a higher price tag, while others are less familiar but offer more budget-friendly choices.

BrandCost
Panasonic$1,700–$2,800
Daikin$1,000–$4,000
Fujitsu$1,100–$8,300
Rheem$1,100–$8,300
Mitsubishi$1,200–$8,650

Efficiency

The efficiency of a mini-split unit significantly impacts its overall cost. A higher Seasonal Energy Efficiency Ratio (SEER) rating means lower monthly energy costs due to increased efficiency. You should factor this in when choosing a unit, especially in a region with extreme temperatures where a higher SEER-rated system may be cost-effective for you. 

Energy-efficient units save money in the long run and often even qualify for utility rebates and government tax credits. However, they may come with a higher upfront cost. Be sure to balance your budget with long-term savings when making a decision.

Location in Your House

Different mini-split units can serve different areas within your home. For example, a single-zone ductless mini-split AC might cool one bedroom, while a quad-zone system could cool your bedroom, bathroom, living room, and basement, depending on the model and square footage. 

The more rooms you cover, the more you’ll pay for the additional indoor units and the labor to install each of them. Also, remember that higher floors need extra installation accessories, so expect to pay $10 to $20 more per foot of materials and a couple of extra hours for labor.

Additional Mini-Split Installation Cost Factors

Aside from the unit type, size, efficiency, and brand of the system you choose, the mini-split installation cost is also impacted by some other factors. 

Permits

Installing a multi-zone mini-split AC system often requires you to secure a permit, and it's recommended that you consult your local municipality for guidance. Typically, permits for such installations can range from $250 to $400, so budget accordingly and ensure compliance with local regulations before beginning your project.

Hiring Contractors

Labor costs of hiring a professional HVAC contractor are typically between $300 and $2,000 for a single-zone system, depending on the mounting location. Multi-zone systems can range between $700 and $3,000

In addition, ductless mini-split AC installation may require a local electrician if you do not have a dedicated 110- or 200-volt box, costing $50 to $100 per hour. You’ll probably need a dedicated electrical circuit, which can cost an additional $250. A local carpenter may also be required to cut the three-inch hole for the refrigerant lines for each unit. They can range from $25 to $50 per hour

And you’ll need a concrete pad to put the ductless mini-split unit on, which may cost several hundred dollars if completed by a professional. If you do that part yourself, factor in the cost of materials (such as lumber and rebar for framing and the concrete mix) as you budget for the project.

Removal of Existing HVAC

When you choose to install a ductless AC unit to replace your old central air system, it's recommended that you remove the old equipment to prevent issues with the components degrading due to not being used. This process involves removing old condensers, ductwork, and thermostats. The removal cost typically ranges from $80 to $150 and ensures a smoother transition to the new mini-split AC system.

Upgrades

Certain upgrades may be necessary or simply desired when enhancing a mini-split system. For instance, if you live in a snowy region, you may need to elevate the unit off the ground and prevent damage. You may also want to add a wireless system operation for convenient temperature adjustments. Below are various common mini-split add-ons and accessories and their average costs.

  • Wall mount bracket: Enables secure wall mounting of the outdoor unit, saving floor space

  • Wireless remote controller: Offers remote temperature control and convenience for homeowners

  • Condenser stand: Elevates the condenser unit, protecting it from ground-level hazards

  • Condensate removal pump: Efficiently drains excess condensation to maintain optimal humidity levels

  • Drain pan heater: Guards against freezing in colder climates, ensuring uninterrupted operation
