Today’s Homeowner Tips
Mount your mini-split on the inside of exterior walls near your outdoor spaces but away from gathering areas. You’ll keep the noise away from your patio and save money on installation.
Mini-Splits Installation Cost by Home Size
The size of your mini-split cooling system is expressed in British Thermal Units (BTUs). The larger the room or rooms you want to cool, the more BTUs you’ll need and the more you’ll spend on your mini-split unit. So, if you have a large room that isn’t well insulated, you will need a larger, more expensive mini-split.
The smallest mini-split AC units can easily cool a 450-square-foot room and start around $2,000 for the unit and installation. But if you want to cool a much larger 1000-square-foot space, you’ll pay between $2,400 and $3,500 for air conditioner installation.
| Home Size | Average Cost |
| Small Room (450 to 600 sq. ft.) | $2,000–$2,500 |
| Medium Room (900 to 1,200 sq. ft.) | $2,500–$3,500 |
| Large Room (1,200 to 2,000 sq. ft.) | $3,500–$6,500 |
| Whole Floor (2,000+ sq. ft.) | $6,500+ |
Which Factors Impact Mini-Splits Installation Cost Estimates?
Although the size of your ductless AC system is among the biggest cost factors, the cost of your ductless mini-split air conditioner depends on several factors. When choosing your new air conditioning system, keep the following factors in mind:
- Brand
- Efficiency rating
- Number of zones
Brand
The air conditioner brand you choose also impacts the total cost of your mini-splits installation project. The most expensive brands, like Mitsubishi and Fujitsu mini-splits, have air conditioning systems that cost $8,700 to $12,000 but also offer smaller units for as low as $1,200. Less expensive brands, such as Rheem or Pioneer, offer larger units as low as $4,800 to $8,100.
| Brand | Low Cost | High Cost |
| Daikin | $1,400 | $8,400 |
| Fujitsu | $2,300 | $12,500 |
| Mitsubishi | $1,400 | $9,000 |
| Panasonic | $1,400 | $5,000 |
| Rheem | $1,400 | $8,500 |
Efficiency Rating
Efficiency, as measured by seasonal energy efficiency ratio (SEER) ratings, is one of the most important considerations before choosing a mini-split system for your home. Most mini-split systems have SEER values between 16 and 25, with the most efficient air conditioning systems having a higher value.
Today’s Homeowner Tips
Generally, a higher SEER rating means your system is more expensive. On average, expect to pay $3,200 for a mini-split system with good energy efficiency and up to $2,000 to $5,500 more for the most efficient systems of the same size. However, this higher cost is worth it, as efficiency upgrades will save you money on your monthly energy bills.
Number of Zones
If you only want to cool a single room, install a single-zone system; for larger or multiple rooms, you may need multiple zones or air handlers. Most single-zone mini-split systems cost between $500 and $5,000 to install. But if you need a multi-zone mini-split, you can expect to pay between $650 and $2,750 for each additional zone.
| Number of Zones | Average Cost |
| Single-zone system | $500–$5,000 |
| Dual-zone system | $2,650–$10,250 |
| Three-zone system | $3,300–$13,000 |
| Four-zone system | $3,950–$15,750 |
| Five Zone System | $4,600 – $18,500+ |
A typical outdoor unit can sustain four to eight zones, so talk to your HVAC technician to determine the best placement for your mini-split system. For instance, you may forgo bathroom or hallway installation as these areas are less heavily used than other, more trafficked rooms.
Professional vs. DIY Mini-Splits Installation
Though we recommend hiring a professional HVAC technician to install your mini-split air conditioner, you can also install part of the system yourself to save money on some labor costs. However, always have a professional HVAC contractor come to your home to inspect and complete your work before you turn on the system.
Doing Mini-Splits Installation Yourself
You can do a mini-split installation yourself, but we recommend having one of the best professional HVAC technicians double-check your installation. Hire a professional if installing a mini-split heat pump, as this project is more complicated.
If you plan to install your mini-split by yourself to lower labor costs, follow these steps:
- Choose a wall that leads outside for your indoor unit.
- Locate studs and drill holes to hang your mini-split.
- Drill a small hole through the wall to the outside.
- Unfold your refrigerant lines.
- Hang your mini-split and connect the control wire.
- Choose the location of your outdoor condenser, either on the ground, mounted, or roof.
- Mount the outdoor unit, connect the pipes, and attach the wires.
Once your mini-split is in place, hire a licensed electrician to wire it. Mini-split air conditioners often need a 220-volt line from your breaker, which can be hazardous if done incorrectly. In case you run into any issues post-installation, familiarize yourself with split AC system troubleshooting.

FAQs About Mini-Splits Installation
What does the installation cost of a mini-split include?
A basic package covers your indoor air handler ($400-$1,800), outdoor unit ($1,000-$5,500), and mounting hardware. Labor adds $700-$3,000 depending on your location— expect higher costs in areas with strict HVAC requirements. Your quote should include refrigerant lines, electrical hookups, brackets, and testing. Set aside extra for permits ($250–$400), electrical work, or special mounting needs. Ask your HVAC contractor for an itemized quote to avoid surprises.
What are the benefits of a mini-split system?
Mini-splits excel at room-by-room cooling control. You can set different temperatures for bedrooms (72°F), living areas (75°F), and guest rooms (78°F when empty), cutting energy costs by 20–30%. They work great in older homes or additions where adding ductwork would cost thousands more. Plus, they run quieter than window units and take up less wall space than traditional through-wall AC units.
Why do mini-split systems cost so much to install?
Each installation involves precise work: mounting units, running refrigerant lines through walls, and connecting electrical systems. Labor costs range from $700 in warmer regions to $3,000 in areas with strict HVAC codes. Most jobs need an electrician ($50–$100 per hour) to install a dedicated circuit and a carpenter ($25–$50 per hour) to cut wall openings. DIY might seem tempting, but professional installation keeps your warranty valid and ensures the system runs efficiently.
How much does it cost to install a four-zone mini-split?
A four-zone mini-split costs $2,600 to $10,700, plus installation ($700–$3,000), permits ($250-$400), and electrical work ($250+). Each room needs its own air handler ($400-$1,800), all connected to one outdoor unit. Real-world example: A recent installation in a 2,400-square-foot home cost $8,500, with zones in the living room, kitchen, and two bedrooms. The homeowner’s energy bills dropped $120 per month in summer by cooling only occupied rooms.
