Let’s look at the financial aspects of installing a single-zone mini-split to ensure a clear picture of what to expect.

Basics of Single-Zone Mini-Split Systems

Before diving into the costs, let’s briefly define a single-zone mini-split heat pump and discuss why correct sizing matters.

Ductless mini-splits provide heating and cooling to a single area or room, replacing central AC systems of the past.

A single zone mini split AC system comprises two units, the outdoor unit and the indoor unit.

Outdoor Unit: The condenser or heat pump is typically installed on an exterior wall or a concrete pad near the area you want to cool or heat.

This unit is responsible for releasing or absorbing heat from the environment, depending on whether you’re using it for cooling or heating.


The compressor, condenser coil, and fan are inside the outdoor unit. The compressor plays a crucial role in pressurizing and circulating the refrigerant. The condenser coil helps dissipate heat generated during the compression process. The fan assists in transferring heat from the refrigerant to the outdoor air.

Indoor Unit: The indoor unit, also known as the air handler or evaporator unit, is positioned within the room or area you intend to condition. Its primary function is to distribute the conditioned air into the space. The indoor unit contains a fan, an evaporator coil, and often a filter.

The indoor unit also features a filter that helps purify the air by trapping dust, allergens, and particles. This filtration process not only improves indoor air quality but also maintains the efficiency and cleanliness of the system.

These two units connect via refrigerant lines that circulate refrigerant between them. This refrigerant cycle is the heart of the mini-split system, allowing it to remove heat from one area and release it in another, thus providing both cooling and heating capabilities.

Cost to Install a Single-Zone Mini-Split: Three Options

Understanding the installation costs of a ductless AC system is essential for your budget. But before you can determine an amount, you’ll have to decide what type of installation will work best for you.

“What’s best for you” may have less to do with your budget, in this case, and more with your comfort level and skill set. Let’s look at your options for different types of ductless mini-split installations.

#1: Professional Installation

Having a professional HVAC contractor install your mini-split may sound the most expensive, but that isn’t always the case.

Depending on where you live and the complexity of your building space or mini-split system, hiring a licensed HVAC professional to install your entire mini-split air conditioner may be your best route.

Hiring professionals to install your single-zone mini-split ensures a smooth and efficient setup. They can also accurately assess your space and recommend the ideal unit size, potentially saving you money in the long term.

On the other hand, a professional will cost you more in terms of labor than if you do it yourself. And, if you are skilled at such projects, you are less likely to run into any unexpected issues along the way.

#2: Do-It-Yourself Installation

A do-it-yourself installation is popular among mini-split owners, particularly those with smaller units and straightforward spaces.

When you choose to DIY your ductless mini split air conditioner system, you can find plenty of how-to guides and installation instructions to help you along the way.

And, even though you will still want to at least consult with an electrician for the wiring component and consider an HVAC tech to pull a vacuum on your lines, a well-designed ductless mini-split system should be a relatively fun and rewarding project for seasoned DIYers.

#3: Complete DIY Mini Split Systems

With most mini-split heat pumps, you’ll require a technician for certain steps of the installation process, even if the person buying the unit is an avid do-it-yourselfer.

But with a true DIY ductless mini-split system like the Blueridge BMX9DIY20, the term “DIY” takes on a new level of independence.

With a DIY mini-split air conditioner, the outdoor unit or condenser already contains the correct amount of refrigerant, so you will not need a technician to fill it. The copper lines included are already under vacuum. These DIY units also have quick-connect fittings that maintain a vacuum until you’re ready to connect.

After you’ve installed the indoor and outdoor units, you screw together the quick-connect fittings, then open the valves to release the refrigerant. It’s that easy.

But the complete DIY mini-split system isn’t for everyone. Not only will you still need an electrician to ensure your electric panel and wiring are up to code, but some people don’t feel comfortable tackling the refrigerant lines and condenser setup. But a DIY single-zone mini-split system may be ideal for someone who enjoys doing an entire project independently.

Ongoing Operational Costs

Beyond your mini-split installation, it’s important to consider the ongoing operational costs associated with your single-zone mini-split system. Make sure you factor in things like:

Energy Consumption: Although mini-splits are highly energy efficient, you’ll still have monthly energy bills. However, these bills are often lower than those of traditional HVAC systems due to the precise temperature control.

Maintenance and Cleaning: Routine maintenance and cleaning are necessary to keep your system running smoothly. This includes cleaning or replacing filters, inspecting components, and ensuring proper airflow.

Potential Repairs: You may encounter repair or replacement costs for parts over the system’s lifespan. Proper maintenance can extend its life and reduce these costs.

Regardless of what route you decide to take with your ductless mini-split system installation, your associated costs will be contingent on your decisions and the complexity of your installation.

For a more in-depth understanding of the various ways to install a mini-split system, consider contacting an HVAC expert for advice.

What Factors Will Affect the Cost to Install a Single-Zone Mini-Split?

Along with the cost of the actual labor for your installation, several other factors influence the cost of installing your single-zone mini-split:

Geographical Location:

Installation costs for mini-splits can fluctuate significantly depending on where you live.

This variation is primarily due to differences in local market rates and the availability of HVAC professionals.

In regions with a higher cost of living, such as major cities, installation labor rates tend to be higher.

Conversely, you might find more budget-friendly installation costs in more rural areas or places with a lower cost of living.

Therefore, obtaining multiple quotes from local HVAC contractors is essential to get a clear picture of the cost landscape in your specific area. This geographical consideration can be a pivotal factor in determining your overall budget for the installation.

Complexity of Installation:

The complexity of the installation process is another vital factor influencing costs.

Unlike a central AC system, a ductless mini-split air conditioning system doesn’t need any ductwork to operate, thus significantly reducing the installation cost.

That said, even with the simplicity of a mini-split single-zone system, not all installation scenarios are created equal.

Factors like the type of walls in your home, the accessibility of installation points, and the layout of your space can impact the job’s complexity.

For example, installing a mini-split on an exterior wall with easy access to the outdoor unit might be relatively straightforward.

However, the installation can become more complex and time-consuming if your space requires access to tight spaces or specialized mounting due to unique architectural features. Complex installations often require more labor and can result in higher costs.

Discussing these specifics with your HVAC installer to get a precise estimate based on your home’s unique characteristics is crucial.

Seasonal Demand:

The time of year you choose for your mini split installation can significantly affect the overall cost. Seasonal demand plays a crucial role in pricing. HVAC contractors often experience higher demand during extreme weather seasons – the hottest and coldest months.

Contractors might charge premium rates during these peak periods due to increased workloads and service demand.
