How Much Does It Cost to Install Mini-splits?

Mini-split installation costs between $1,805 and $4,435 for a single unit. However, the average cost for a mini-split is $2,995. This total cost includes the mini-split unit and labor costs. If you need electrical work, permits, or refrigerant lines, your mini-split installation may cost more. In addition, higher efficiency units and certain brands can cost $8,700 or more.

Mini-splits Installation Cost by Type

Mini-split systems cost between $1,805 to $4,435, but the total cost depends on the type of mini-split you install. There are four main types of mini-split systems: wall-mounted, recessed, ceiling-mounted, and floor mounted.

Type of Mini-split SystemLow Unit CostHigh Unit Cost

Ceiling-mounted Mini-split Cost

Installed on your ceiling, ceiling-mounted mini-splits provide the most airflow of all mini-split systems. A ceiling-mounted mini-split costs between $3,030 to $3,805.

Floor-mounted Mini-split Cost

Floor-mounted mini-split systems are installed on your wall near the floor. This mini-split type is the best option if you have tall windows or low ceilings. They cost between $1,300 to $4,435.

Recessed Mini-split Cost

Recessed mini-splits, also known as concealed mini-splits or ceiling cassettes, are the most inconspicuous mini-split system. These systems can be connected to one or more ducts and are perfect for heating and cooling large areas. Recessed mini-splits cost between $2,095 to $2,955.

Wall-mounted Mini-split Cost

Wall-mounted mini-splits are installed on your wall near the ceiling. As the most affordable type of mini-split system, these are also the most popular installation choice. On average, wall-mounted mini-splits cost between $1,805 to $4,435.

Mini-Splits Installation Cost by Unit Size (BTUs)

The size of your mini-split cooling system is expressed in British Thermal Units (BTUs). The larger the room you want to cool, the more BTUs you’ll need and the more you’ll spend on your mini-split unit.

The smallest mini-split AC units can easily cool a 450-square-foot room and start around $1,805 for the unit and installation. But if you want to cool a much larger 1000-square-foot space, you’ll pay between $2,910 and $3,330 for air conditioner installation.

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


The air conditioner brand you choose also impacts the total cost of your mini-splits installation project. The most expensive brands, such as Fujitsu and Mitsubishi, 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, offer larger units as low as $4,800 to $8,100.

BrandLow CostHigh Cost

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 $3,000 for a mini-split system with good energy efficiency and up to $2,000 to $5,000 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 $1,800 and $4,435 to install. But if you need a multi-zone mini-split, you can expect to pay between $600 and $2,500 for each additional zone.

Number of ZonesAverage Cost
Single-zone system$2,000–$7,500
Dual-zone system$2,700–$8,000
Three-zone system$3,400–$10,500
Four-zone system$4,100–$11,000
Five Zone System$4,335 – $13,500+

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:

  1. Choose a wall that leads outside for your indoor unit.
  2. Locate studs and drill holes to hang your mini-split.
  3. Drill a small hole through the wall to the outside. 
  4. Unfold your refrigerant lines.
  5. Hang your mini-split and connect the control wire.
  6. Choose the location of your outdoor condenser, either on the ground, mounted, or roof.
  7. 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.

Final Thoughts About Mini-Splits Installation Cost

Mini-split air conditioners are an excellent choice for homeowners who don’t have existing ductwork. These cooling systems can be installed on your wall, floor, or ceiling, cool your home in the summertime, and even heat your home in the winter. On average, mini-split installation costs between $1,805 and $4,435. However, depending on the brand, size, and number of zones, you can spend as much as $13,000 on a new mini-split system.

FAQs About Mini-Splits Installation

What does the installation cost of a mini-split include?

Mini-split air conditioner costs often include installation, the mini-split unit, and labor. If you need electrical work, more than one mini-split installed, or need a new thermostat, your mini-split installation costs may increase.

What are the benefits of a mini-split system?

If you have an older home that doesn’t have extensive ductwork, a mini-split system can be a great option. Instead of spending thousands to install new ductwork, you can install mini-splits in the most trafficked rooms of your home. If you install several units in your home, you’ll have airflow as good as central AC.

Why do mini-split systems cost so much to install?

More expensive brands and higher efficiency units can increase installation costs drastically to upwards of $13,000. You’ll also pay more for each additional unit if you need a multi-zone mini-split system.

How much does it cost to install a four-zone mini-split?

For a four-zone mini-split unit, expect to pay between $4,100 and $11,000. Buying a less efficient unit can save you money upfront, but you may pay more monthly on your energy bills.
