What is a Ductless Mini-Split System?

Ductless mini-split HVAC systems are gaining popularity, but is it the right choice of system for your home? Find out more.

A ductless mini-split system (sometimes just called a mini-split) is typically a wall-mounted heat pump or air conditioner. As the name implies, it can heat or cool a space without any ductwork. Because of this, it is a popular choice for older homes without existing ductwork or residential or commercial buildings where it would not be feasible or affordable to install the appropriate ductwork for a central air conditioner.

In this article, we are going to discuss how a ductless mini-split system works and the advantages it offers to home and business owners over other alternatives.

How Does a Ductless Mini-Split Work?

Just like a central air conditioner, a ductless mini-split system consists of an indoor air handler and an outdoor compressor.

A central air conditioning system collects the air in one central location, usually an attic or closet. The air handler cools the air and distributes it throughout the house through the ductwork.

A ductless mini-split system is physically located in the room that it is cooling, eliminating the need for the ductwork. One or multiple air handlers can be connected to one outdoor compressor.

What are the Advantages of a Ductless System?

Residential Mini Split

Ductless systems have several advantages over central air units for some homes and businesses.

No Need to Install Ductwork

The most obvious advantage is the fact that you do not need to install ductwork. Homeowners looking for a heating and cooling system for a single room that is not supported by existing ductwork, or those living in buildings that cannot support new ductwork should consider a mini-split system.

Energy Efficiency

Ductless mini-split systems are more energy efficient than central air units. This increased efficiency is due to a significant portion of your home’s energy waste takes place within the ductwork. According to Energy.gov, approximately 30% of your home’s energy waste occurs within the ductwork.

Easy Zoning

Because each room has its own unit, mini-splits are an affordable alternative to those seeking a zoned heating and cooling system. Every room with a ductless system will have its own thermostat, allowing you to control the temperature in individual rooms.

Heating & Cooling

Most ductless systems are heat pumps, which can provide both heating and air conditioning, thereby eliminating the need for a separate heating unit.

What are the Disadvantages of a Ductless System?

Cost

If you are installing a ductless system throughout the entire house, the initial cost can be two to three times greater than a central air system. You will recoup some of the initial expenses through lower electric bills, but you might be looking at many years before breaking even. If you are concerned about the lifetime expenses involved with a mini-split system, contact your local HVAC provider.

Aesthetics

Because these units are located in the rooms which they are heating or cooling, some home or business owners might not like the look of the unit.
