Introduction to Ductless Minisplit AC Systems

What are Ductless Minisplit AC Systems?

A ductless minisplit AC system, sometimes referred to as a mini-split, is a type of air conditioning system that doesn’t require ducts to cool your home. These systems are primarily composed of an outdoor compressor and an indoor air-handling unit.

How Do Ductless Minisplit AC Systems Work?

Ductless minisplit AC systems work by having the outdoor unit compress the refrigerant, which is then circulated to the indoor units to cool the air. Each indoor unit can be controlled independently, allowing for zoning or the cooling of individual rooms.

The Pros of Ductless Minisplit AC Systems

Energy Efficiency

One of the main advantages of ductless minisplit AC systems is their energy efficiency. Unlike traditional HVAC systems, which can lose a significant amount of energy through ductwork, ductless systems deliver air directly into different zones, reducing energy losses.

Flexibility and Convenience

Ductless minisplit AC systems provide flexibility because they allow for zoning. This means you can cool individual rooms or areas of your home to your desired temperature. They’re also easy to install, especially in homes without existing ductwork.

Improved Air Quality

Ductless minisplit AC systems often have multi-stage filtration that can significantly reduce dust, bacteria, pollen, allergens, and other particulates in the air.

The Cons of Ductless Minisplit AC Systems

Installation Cost

The initial cost of installing a ductless minisplit AC system can be higher than other cooling systems. However, the energy savings over time can offset this initial investment.

Aesthetic Considerations

While ductless minisplit AC systems are compact, some people find the indoor units less aesthetically pleasing than traditional HVAC grilles or vents.


While all AC systems require maintenance, ductless minisplit AC systems require more frequent maintenance, such as cleaning or replacing the filters.

Choosing the Right AC System for Your Home

When choosing an AC system for your home, it’s important to weigh the pros and cons of each type. Ductless minisplit AC systems offer many advantages, but they may not be the right fit for everyone.
