How Much is a Ductless Mini Split?

When it comes to cooling and heating your home, finding the right system for your specific needs is key. One common type of system that many homeowners are choosing to install is a ductless air conditioning system. But how much is ductless air conditioning? This article aims to provide a comprehensive guide on everything you need to know about the cost, benefits, and considerations of ductless air conditioning systems.

How Much Does it Cost to Install Ductless Air Conditioning?

The average cost to install a ductless air conditioning system largely depends on the type of unit and the complexity of the installation process.

Generally, single-zone systems with one outdoor compressor and one indoor air handler can range from $1,500 to $3,000.

Meanwhile, multi-zone systems, perfect for larger homes, are typically pricier, costing anywhere from $2,500 to $7,500 for professional installation.

How is a Ductless Air Conditioning System Installed?

Ductless air conditioning system installation involves mounting an indoor unit on the interior wall or ceiling, and an outdoor unit (the compressor) on an exterior wall.

Refrigerant lines are then run through a small hole in the wall, connecting the two units. The indoor air handler then cools or heats the air as needed and redistributes it throughout the room.

What Size Mini Split Do I Need?

The size of the mini split you’ll need depends on the square footage of the area you want to cool or heat.

For example, a 13,000 BTU unit can typically cover a space up to 500 square feet, making it ideal for small rooms. Larger units of around 36,000 BTUs, on the other hand, can cover spaces up to 1,000 square feet and are suitable for larger homes.

Can a Ductless Mini Split Cool Many Rooms?

A ductless mini split can cool many rooms when set up as a multi-zone system. Each indoor unit in a multi-zone system can be controlled independently, allowing for different temperature settings in each room.

Can a Ductless Mini Split Heat as Well?

Yes, a ductless mini split system can provide both cooling and heating functions due to the heat pump included in the outdoor unit.

This feature makes them an energy-efficient system for maintaining comfort year-round.

What Are the Benefits of a Mini Split?

  1. Energy Efficiency: Mini-splits have high Seasonal Energy Efficiency Ratio (SEER) ratings, reducing energy bills.
  2. Flexibility: They can be installed in various areas in your home, with no need for ductwork.
  3. Zoning: Multi-split systems allow for individual temperature control in different rooms.
  4. Quiet Operation: They run more quietly compared to central air conditioning systems.

What Are the Cons of a Mini Split?

  1. High Initial Costs: Installation costs can be higher than traditional systems.
  2. Aesthetic Considerations: Some people may not find the indoor units visually appealing.
  3. Requires Professional Installation: DIY installation is generally not recommended.

Is a Ductless Mini Split More Affordable Than Central AC?

While the initial cost of a ductless mini-split system might be higher than a central air conditioning system, it can be more cost-effective in the long run.

The high efficiency rating of mini splits can result in lower energy bills, offsetting the initial costs over time.

How to Choose the Right Mini Split?

Choosing the right mini split involves considering your home’s square footage, how many rooms you want to cool or heat, the unit’s SEER rating, and your budget.

It’s best to consult with a professional to determine the right type of unit and size for your needs.

How to Maintain a Ductless Mini Split?

Maintaining a ductless mini split involves regularly cleaning or replacing the air filters, cleaning the outdoor condenser unit, and having it professionally serviced at least once a year.

Can You Install a Mini Split Yourself?

While there are installation kits available for ductless mini-split air conditioners, it’s generally recommended to have a professional install the system. This ensures it’s done correctly and safely, preserving the warranty, and optimizing the unit’s efficiency.

Are Ductless Mini Splits Noisy?

Compared to traditional central air conditioning systems, ductless units are significantly quieter. The majority of the noise-producing machinery is located in the outdoor unit, which can be placed away from living areas.

Are Mini Splits Worth It?

Given their high energy efficiency, zoning capabilities, and flexibility in installation, many homeowners find that mini splits are worth the investment, particularly for those living in hot climates or those needing to cool or heat individual rooms.


Determining the cost of a ductless air conditioning system depends on a variety of factors, including the type of unit, installation costs, and the size of your home.

Despite their higher initial cost, their high efficiency and ability to cool and heat individual rooms can make them a cost-effective solution over time.

With this guide, you should now have a clearer picture of how much a ductless air conditioning system might cost and whether it’s the right solution for your needs.
