How Much Does It Cost To Install A Ductless Mini-Split Air Conditioner?

Ductless mini-splits are becoming increasingly popular, especially as more people look for ways to reduce their energy consumption. A ductless mini-split air conditioner is a great way to cool your home or office without requiring ductwork. These systems are very efficient and can save you money on your monthly energy bills. But what does it cost to install a ductless mini-split? The answer to this question depends on a few factors, such as the size of the unit, the type of unit, and the unit’s location. 

What is a Ductless Mini-Split Air Conditioner?

A ductless mini-split air conditioner is a type of air conditioning system that doesn’t require ductwork. It includes one outdoor and one indoor unit, connected by refrigerant tubing and electrical wiring. The indoor unit is often wall-mounted or ceiling-mounted and delivers heated or cooled air directly into the living space. Each unit has its own thermostat, so you can cool different areas of your home or office to different temperatures.

In most cases, a single-zone system may be enough to provide heating and cooling comfort for your home. If not, ductless multi-zone systems combine one outdoor unit with up to five indoor units, providing comfort to an entire home. Your ductless installation contractor will know what’s best for your square footage and space. 

Factors Affecting the Cost to Install a Ductless Mini-Split Air Conditioner 

There are several factors that will affect the cost of installing a ductless mini-split air conditioner in your home. The type and size of unit you choose will affect the cost, as different units have different features that may require additional installation work. The unit’s location in your home will also play a role in the final cost, as some locations may be easier to access than others. Finally, the company you choose to install your ductless mini-split air conditioner will also affect the overall cost. 

Cost to Install a Ductless Mini-Split

The installation cost for a ductless mini-split air conditioner can vary depending on a few factors. The size of the unit, the type of installation, and the project’s complexity are all factors that can affect the cost. A ductless mini-split air conditioner installation typically costs $8,000, depending on the customer’s needs and choice. This cost includes all electrical work, permits, equipment, and parts. If you have an older home with existing ductwork, the installation may be more complex and, therefore, more expensive.

Although the cost to install a ductless system is high up front, homeowners typically see a reduction of their heating and cooling costs throughout the year. The average savings reported is around 25%-50% a month. In addition to monthly savings, there are many ways to reduce the upfront cost of ductless installation including: 


Most Washington state utility companies offer significant rebates for homeowners replacing inefficient heating and cooling systems with more efficient systems, such as the ductless mini-split. These rebates can help you save significantly on your ductless heat pump installation. 

Tax Credits 

As part of the recently passed Inflation Reduction Act, starting in 2023 you can receive a tax credit of up to $2,000 for the installation of a highly efficient ductless heat pump. Be sure to consult a tax professional to determine your eligibility. 

Financing Programs

Nowadays, lenders make financing a ductless mini-split installation quite affordable. For example, a local Washington state utility company even has its own financing program. 

Lifespan and Efficiency of a Mini-Split

With proper maintenance, a mini-split air conditioner can last upwards of 20 years. This is far beyond the typical 12 to 15 years that most HVAC systems last, so it’s safe to assume that your mini-split system will last longer than most other options.

When it comes to the efficiency of a ductless mini-split AC, there are a few things that you need to consider. The size of the space or area that needs cooling will affect how efficient the split system is. The unit’s location will also play a role in its efficiency. Be sure to consult with a ductless installer in Olympia to ensure you have the right-sized system for your space. 

How Is Ductless Mini-Split Better Than Traditional HVACs?

A ductless mini-split air conditioner has numerous benefits over a traditional HVAC system:

    • They are much more efficient, meaning they cost less to operate and can help save you money on energy bills. Additionally, they take up far less space than a ducted system and can be easily installed in any room, regardless of size or layout.

    • Ductless mini-splits are also much quieter than central HVAC, making them ideal for use in bedrooms or other areas where the noise level is a concern. 

    • A ductless mini-split is different from central air in a few key ways. It does not require any ductwork, which can save you both time and money during installation. Additionally, it is more efficient than central air since it doesn’t lose cooled air through leaky ductwork.

    • These units provide targeted cooling and heating. Rather than purchasing and installing an entirely separate heating source, a mini-split can both heat and cool a room, making it the perfect option for year-round comfort.
