Split Unit AC Cost Considerations

Homeowners thinking about installing a split AC system, or ductless AC system, in their homes should be aware of all the associated mini split installation cost averages. After all, it’s necessary not only to purchase the split AC unit itself, but to have it installed by a trained and qualified HVAC professional. Unlike a simple window unit, there are a few specific connections that must be made between the condenser and the evaporators to ensure the system runs properly. Furthermore, proper insulating must be done to maximize energy efficiency.

When hiring an HVAC company or contractor for mini split AC installation, there are some specific factors that must be taken into account. The split unit AC cost ranges between $1,000 and $8,500. Beyond that, however, there are of course labor costs associated with any mini split installation.

Depending on the amount of time it takes to install the unit and the number of evaporators being installed with it, labor can cost anywhere from $300 to $1,500 and usually takes around 10 hours. Finally, there is also the cost of the materials needed to properly install and insulate the AC unit, such as tubes and insulation. Homeowners should expect to spend around $40 to $50 on these materials altogether.

Researching and gathering quotes from various HVAC companies is key. Furthermore, having the installation done in the fall or winter can yield lower costs, as HVAC companies tend to be less busy. Homeowners should also be on the lookout for special promotions and discounts, such as free installation or discounted labor.

Advantages Of Mini Split System

Homeowners who do not have ductwork in their homes and are considering a mini split air conditioning system should weigh both the advantages and disadvantages of a split unit AC.

One of the largest advantages of installing a mini split AC system is the fact that there is no need to retrofit an existing home with the appropriate duct and ventilation work, which can cost thousands of dollars. Furthermore, since these ductless AC systems do not require much complex wiring or tubing, they tend to take less time to install, lowering the average cost to install a mini split AC system.

Another great aspect of a split air conditioner is the fact that they can be customized to the home. For example, one condenser may have as many as four evaporators connected to it, all of which can serve different rooms around the home. These evaporators can be independently controlled, which is great for keeping electric costs down. For example, if a homeowner wants to cool just one room in the home, all you have to do is shut off the evaporators to the rest of the home.

Finally, unlike a window AC unit, most mini splits are mounted on the ceiling and do not need to be exposed through a window to the home's exterior. This creates an increased sense of security for homeowners as break-ins through window units are sadly quite common.

Disadvantages Of Mini Split System

Of course, the costs of operating mini split AC will vary. While some are not nearly as energy efficient as a forced-air system like central AC, according to, mini split AC units can typically cost 20% to 60% less to run than a central air conditioning unit.

Furthermore, not all homes are well suited for mini split air conditioning systems. It will take a qualified HVAC contractor to come out to a home, assess the space and determine whether or not such a system can be installed. Finally, some homeowners are also unhappy about the space requirements of the split AC system, as well as the increased maintenance.

Ductless AC Vs. Central AC

If you have ductwork in place, it pays to compare the pros and cons of mini split units to central air conditioning units.

Ductless AC units

  • Mini split systems present significant savings if you do not have ducts in place.
  • Mini split systems are easier to install than central AC units.
  • Mini splits can provide both AC and heat.
  • Ductless air conditioners are more energy efficient than central AC units.
  • Some people think min split AC units are ugly and take away from the interior design.

Central AC

  • For the most accurate cooling throughout the home, central AC is the way to go.
  • If you do not have ductwork in place, your total installation cost will be very high.
  • The system can last up to 20 years with proper maintenance.
  • Central air conditioners are less expensive to run after installation.

Split unit AC costs range, but you can lower your split AC installation cost. See how.

Mini Split AC System Types

When choosing a mini split AC system, homeowners need to decide which unit is best for them. In general, there are two common types of mini splits:

  • Single Zone
  • Multiple Zone 

Single zone units are less expensive, but are generally only used to cool one area of the home. These are ideal for smaller spaces such as studio apartments. However, multiple zone units are designed to cool several spaces within a home. These also tend to be more expensive, as the capacity for these systems must be higher and more powerful.

How Mini Splits Work

Like other air conditioning systems, mini split AC systems move hot and cold air where you need it. In the summer, your mini split evaporator will remove the heat inside your house, transport it to you condenser and release it outside. In the winter, the system can reverse the process and bring cold air outside.

Furthermore, mini splits are also great for moving cold or hot air from one room to the other. Therefore, if your basement is cold (which they tend to be) and you’re sleeping in your bedroom, the mini split can take that cold air from the basement and move it upstairs.


Like other AC systems, the capacity of mini splits is based on its BTU and SEER rating. Both help determine the strength of airflow. A single unit should be rated at 24,000 BTU with a SEER of at least 17. To determine what system you need, please see our AC Unit Installation Cost Guide.

Where Can You Install Mini Splits?

The location of your mini split AC system must be considered before purchase. Luckily, you can install your mini split AC system in a few different areas.

Mini splits can be attached to your ceiling or wall. High up on the wall is more common, but as time has evolved, more homeowners are disguising them in the ceiling. If you choose to install your mini split AC unit in the ceiling, you can have it suspended, recessed or concealed. As you might imagine, recessed or concealed units are very popular for smaller units. The less noise in the room, the larger it will feel.

The cost to install ductless AC should not exceed $3,000. See how to install a mini split.
