Choosing between ductless AC and central air can significantly impact your home's comfort and energy expenses. While both systems offer cooling efficiency, their upfront costs, installation, and long-term savings vary.

In this article, we will break down the main differences and pros and cons of each option to help you make the right decision for your home. So, let’s dive into it. 

What is Ductless AC 

A ductless AC, also known as a mini-split system, is a cooling solution that doesn’t require ductwork to distribute air. It consists of an outdoor compressor and one or more indoor air-handling units, which are mounted on walls or ceilings and connected by a small conduit.

What is Central Air Conditioning System 

A central air conditioning system is a cooling system that uses a network of ducts to distribute cooled air throughout an entire home or building. It consists of a central unit, which includes an outdoor compressor and an indoor evaporator coil, that cools the air before pushing it through ducts to various rooms via vents.

Main Differences Between Ductless AC Vs. Central Air Conditioning System 

It is crucial to know the main differences between these two types of conditioning systems to understand which one will work best for your home. These include differences in installation complexity, energy efficiency, cooling coverage, and overall maintenance costs. 

Installation Complexity 

Ductless AC systems are easier to install since they only require mounting indoor units and connecting them to an outdoor compressor. Central air, however, requires extensive ductwork, which can be costly and time-consuming, especially in older homes. 

Energy Efficiency 

Ductless systems are generally more energy-efficient because they eliminate duct losses, which can account for up to 30% of energy waste in central air systems. Many mini-splits also come with inverter technology, allowing them to adjust output and reduce energy consumption.

Cooling Coverage 

Central air is designed to cool an entire home evenly, making it ideal for larger spaces. Ductless AC provides zoned cooling, allowing you to adjust temperatures in different rooms individually, which can lead to energy savings and personalized comfort. 

Upfront and Maintenance Costs 

Ductless AC typically has a lower upfront cost for homes without ducts but may require multiple indoor units for whole-home cooling. Central air has a higher installation cost but can be more cost-effective for large homes already equipped with ductwork. 

Maintenance for ductless systems includes cleaning filters, while central air requires duct cleaning and servicing of the entire system.

Noise Levels and Aesthetic 

Ductless AC units are visible on walls or ceilings, which may not suit all interior designs, while central air remains hidden with only vents visible. 

Noise levels can also differ. Ductless systems tend to be quieter since the compressor is outside, whereas central air can produce noise from ducts and vents.

Pros and Cons of Ductless AC 

Ductless AC systems are flexible and energy-efficient cooling solutions. However, as with any other solution, it has both pros and cons. Understanding both limitations and benefits will help you make a decision that truly meets your needs. 

Pros 

Ductless AC systems provide several advantages, especially for homes without existing ductwork or for those looking for zoned cooling options.

• Higher energy efficiency due to the elimination of duct losses

• Easier and quicker installation compared to central air systems

• Zoned cooling allows for customized temperature control in different rooms

• Quieter operation since the compressor is located outside

• Improved indoor air quality with multi-stage filtration and no ductwork to collect dust. 

Cons

Despite its benefits, ductless AC may not be ideal for every home, particularly when considering aesthetics and cost.

• Higher upfront cost per unit compared to central air systems

• Indoor units are visible and may not blend well with all interior designs

• Requires regular maintenance, such as cleaning filters, to maintain efficiency. 

Pros and Cons of Central Air Conditioning System 

Like ductless AC systems, central air conditioning systems have advantages and drawbacks. Weighing the pros and cons can help determine if this system is the best choice for your space.

Pros 

Central AC is a reliable cooling solution that ensures even temperature distribution throughout the entire home.

• Provides consistent and uniform cooling across all rooms

• Hidden ductwork keeps the system out of sight for a clean aesthetic

• Works well for larger homes, efficiently cooling multiple rooms at once

• It can be integrated with a home’s heating system for year-round climate control

• Increases property value by offering a sought-after home feature. 

Cons 

While central AC is effective for whole-home cooling, its downsides may impact installation and energy use.

• Requires ductwork installation, which can be costly and time-consuming

• Duct leaks and inefficiencies can lead to higher energy consumption

• Regular maintenance, including duct cleaning, is necessary to ensure optimal performance. 

Which One to Choose 

As far as we understand, cost efficiency depends on your home’s setup, usage, and long-term energy savings. So, the question is which one should you choose for your home. Let’s take a look at the main factors to consider.  

Home Size and Layout 

Your home's size and layout are key in determining the best cooling system. Central air is ideal for larger homes with existing ductwork, ensuring consistent cooling in all rooms. Ductless AC works better for smaller homes, additions, or spaces where zoned cooling is preferred. 

Energy Efficiency in Operating Costs 

Ductless AC systems are generally more energy-efficient since they avoid duct losses and allow for zoned cooling, reducing wasted energy. Central air can be efficient in well-insulated homes but may consume more power due to duct-related inefficiencies. Considering long-term energy costs is essential when making your decision. 

Installation and Maintenance 

Installing central air requires ductwork, making it a more complex and expensive project if ducts aren’t already in place. Ductless systems are easier and quicker to install but may require multiple units for whole-home cooling. Maintenance also differs; central AC requires duct cleaning, while ductless units need regular filter cleaning. 

So, central air may be more economical for larger homes with existing ducts in the long run. You can explore both options at Voomi Supply for central AC or Voomi Supply for ductless mini-split systems to find the best fit for your needs.
