Why You Should Consider a Ductless Mini-Split System

In a majority of houses, there are rooms or areas of the home that experience temperature differences. From sunrooms that are a little too warm to master bedrooms that stay cold in the winter, there may be some limitations to your HVAC system. Even though your cooling and heating systems might be functioning properly, there are situations where the equipment can’t sufficiently heat or cool all areas. Additionally, outside forces such as sunlight and shade can also play a role in the temperatures of certain areas in the house.


Whether your central air system is functioning properly or not, temperature inconsistencies are a common occurrence in many homes. If you have gone through the troubleshooting scenarios with your air filters, ductwork, and other parts of your system, it could mean that you need to investigate other solutions. To solve the issue of hot or cold spots around the house, many homeowners are turning to ductless systems for certain areas of their homes. If you are considering ductless mini-split systems, there are a few things to consider.

What is a ductless mini-split system?

A ductless mini-split is similar to traditional central air systems that deliver hot and cold air to the rooms in your home. As the name suggests, however, mini-splits don’t require ductwork to transfer air. A mini-split has an outdoor compressor and condensing unit that works with an indoor air handler. The indoor unit is usually mounted on the ceiling or wall in the area where hot and cold air is required. Like a traditional HVAC outdoor unit, the outside compressor can be placed on a pad. The separate components are connected with a power cable and copper refrigerant tube instead of ductwork.

Ductless systems are also known as zoned systems as they have the capabilities to control specific rooms or zones within the home. In many systems, the indoor unit and outdoor unit work together to control the temperature in one area. Depending on your needs, other units allow several indoor units to be connected to one outdoor unit to control multiple rooms. The benefit of these systems is that they don’t require a complex duct system and can usually be installed in a single day.

Aside from not requiring ductwork, another big benefit of a mini-split is the customization and flexibility of temperature control. If you have room additions, an unheated garage, a cold and damp basement, or a blazing sunroom, a ductless mini-split might be the solution. Additionally, you can also add a mini-split to an area already serviced by your HVAC system to provide more support. Many homeowners have also found a mini-split to be a good choice for older homes with non-functional or antiquated systems.

In homes where preferences and temperature requirements differ, a mini-split system can be a great solution. As a zoned comfort solution, these systems can allow one area to be warmer and another room to be cooler. No matter if you have a new home or an older house, it can be beneficial for regulating different parts of the home.

A mini-split system can also prove to be much more energy-efficient than a traditional system. Losses through the ductwork can account for up to 30 percent of a home’s energy consumption. Considering that your HVAC system can account for half of your monthly energy costs, ductless systems can prevent air leaks and wasted energy consumption.

A mini-split system is a heating and cooling system that allows temperature control in individual rooms and spaces. If you have built a home addition or have rooms with specific needs, a mini-split system could be the solution without requiring ductwork and other construction.
