Central and Ducted Air Conditioning Vs. Ductless/Mini-Split Air Conditioning

Choosing the right air conditioning system for your home is a crucial decision that affects your comfort, energy efficiency, and budget. 

Two popular options are ducted air conditioners (commonly known as central air conditioning systems) and ductless mini-split systems. 

Understanding the differences between these systems can help you make an informed choice. In this article, we will go through the differences between ducted central A/C systems and ductless mini-split systems.

What are Ductless and Ducted A/C’s? What is The Difference?

Ducted air conditioners, commonly known as central air conditioning systems, use a network of ducts to distribute cool air throughout a home, with a central indoor unit connected to an outdoor compressor. 

These systems typically involve significant installation efforts, especially in homes without existing ductwork. 

Ductless air conditioners, or mini-split systems, do not require ducts; instead, they use individual indoor units connected to an outdoor compressor. 

Efficiency

Mini-split systems are known for their high energy efficiency. One key reason for this is that they do not require ductwork. 

Poorly sealed ductwork in central air conditioning systems can lead to energy losses of up to 30%, which translates to higher energy bills and wasted energy that escapes into your walls, attic, or crawlspace. 

By eliminating ducts, mini-split systems ensure that all the energy consumed is used for cooling, making them a more efficient option.

Built-in Zoning

Ductless mini-split systems have built-in zoning capability. A single outdoor compressor unit can connect to one or multiple indoor units, each with its own thermostat. 

This allows you to control the temperature of individual rooms independently. Zone control is particularly beneficial if different areas of your home have varying temperature needs or if different household members prefer different temperatures. 

Additionally, you can save on energy costs by only cooling the rooms that are in use. While some central air systems offer zoning options, they are not as flexible as mini-split systems. Central air conditioning typically cools the entire house at once, which can lead to energy waste if certain rooms are not in use.

Utility Bills

The cost of running central air conditioning and ductless mini-split air conditioning systems can vary based on the climate, the BTU output of the unit, and usage patterns. 

On average, it can cost between $96 (€87.94) and $168 (€153.89) per month, which translates to approximately $1000 (€916.00) to $1200 (€1,099.20) per year. This is about 30% higher than the yearly cost of operating a ductless A/C system. 

Duct Maintenance

Central air conditioning systems require regular maintenance of the ductwork. Moisture inside the ducts can lead to mold and mildew growth, which can result in unpleasant odors and potential health risks. 

Annual maintenance is recommended, adding an additional expense to your yearly budget. Mini-split’s do not use ducts so homeowners do not need to worry about duct maintenance. 

Retrofit Costs

When it comes to retrofit costs, installing a ductless mini-split system is more affordable than installing a central air conditioning system. The average cost is $3,300 (€3,022.80) for a ductless single zone mini-split system. A 3-zone ductless A/C system costs an average of $7,800 (€7,144.80).

Ductless A/C systems are also quicker and less invasive to install than ducted A/C systems, especially in homes without existing ductwork.

Installing a new HVAC system with ductwork is significantly more expensive, with an average cost of $11,500 (€10,534.00). The higher cost is due to the need for extensive ductwork installation, which is both labor-intensive and material-intensive.
