Mitsubishi Ductless MiniSplit HVAC Pricing

How much will a ductless installation in Frederick, MD Cost?

Last month, we wrote a blog article on the pros and cons of ductless mini split hvac systems to help you decide whether it is the right investment for your needs.

Ductless HVAC system pricing can be complex, so we wanted to share some information that will help you understand exactly what you are paying for. And that so you have a better understanding when talking to your HVAC contractor.

Afterwards, we will go over general pricing information and costs that apply to ductless hvac systems. Then we will dive further into how much a ductless hvac system might end up costing you right here in Frederick, MD.

Ductless Minisplit Cost Factors

What is the cost of installing a ductless system?

“It depends”

This can be one of the most annoying and frustrating answers for any homeowner. However, it is often the best response, at least without a detailed review of your specific home needs.

Nevertheless, let’s talk about some of the factors that contribute to the cost of a ductless HVAC system – no matter where you live. Frederick, MD or elsewhere!

Home Size

Do you live in a large, vast house with lots of rooms? Or a small, comfortable apartment? A tiny condo? It is vital to select the “right-sized” solution when installing a new ductless hvac system.


Larger (or more) multi-room systems necessitate larger (or more) air compressors, longer refrigerant lines, more air handlers, and more installation time…ultimately increasing installation costs.


Smaller, single-room solutions, such as those for condos, apartments, and individual spaces, on the other hand, are more affordable.

Home Age

There’s no disputing the appeal of older homes, or the difficulty that comes with them in maintaining the right temperature.

If you own an older home, you may need to upgrade your electrical system to bring it up to code and complete the installation.


If your contractor performs an in-home estimate, he or she will be able to inform you if this is required.

Existing Systems

Do you have a fuel-guzzling cooling or heating system? Is your old and inefficient, traditional HVAC system no longer capable of keeping your house comfortable?

The removal of an old system adds labor and associated costs. On the plus side, split-ducted and multi-position ducted systems can be outfitted with your existing ductwork and hvac system.


Ductless systems do not require the bulky, inefficient, and expensive ductwork that traditional HVAC systems do!

Instead, the refrigerant lines are routed through small holes. For example, to allow two refrigerant lines, control cables, and the necessary electrical connections, a three-inch hole is required.

Your contractor can easily install these discrete holes in closets and other small spaces if you are retrofitting your home or adding a system to a new room (e.g., an addition).

It will increase your costs, but only at a fraction of the cost and hassle of traditional ducted HVAC systems.

Ductless HVAC System Parts Costs

The cost of your ductless mini split system  can vary greatly but generally falls within the realm of $2,000 to $15,000 on a national average.

On average, you are looking to spend around $4,000 with installation, but this all depends on your ductless ac needs and the size of your home.

Let’s break it down:

Outdoor Unit / Compressor: Depending on your home, brand, and quality of your ductless mini split, your outdoor until will range from $1,000 to $6,000. Your HVAC expert will help you decide which one is best for you.

Indoor Wall Mount: These will typically range from $400 to $1,000 for each unit.

Indoor Ceiling Mount: You can expect to spend $700 to $2,000 for these units.

Installation Kit: The lines, wires, drain tubes, and other non-unit parts will run from $300 to $500.

Refrigerant Lines: $5 per foot.

Installation: This will run you anywhere from $300 to $1,500 or more, depending on how many units you need. The average installation cost sits around $500.

Maintenance: You will maintain your ductless ac system on the same schedule you would a traditional HVAC. This can add an annual cost of $200 to $400.

Cost to Run: If you are starting at a 6,000 BTU ductless mini split, you are looking to pay around $.23 per hour. This can range to $.91 per hour, depending on the size of the unit.

Keep in mind, these costs can vary based on the company you work with, your needs, and the area you live. These are just rough estimates, and your HVAC contractor will give you a better idea of the cost.
