Mini-Split vs Central Air: Which is Best for You?

Published April 18, 2025

Choosing between a ductless mini-split system and a central air conditioning system can be challenging. Each has its strengths and weaknesses depending on your home’s layout, budget, and cooling needs. This guide will help you compare the two so you can make the right decision.

1. Installation

Mini-split: Easier to install, especially in homes without existing ductwork. Units mount on walls and only require a small hole for tubing.

Central air: Requires ductwork, which can be expensive and invasive to install if your home doesn’t already have it.

2. Efficiency

Mini-splits are generally more energy-efficient since there’s no energy loss through ducts. They also allow zone cooling, which means you can control the temperature in each room independently.

Central air systems may cool the entire home uniformly, but they often waste energy pushing air through ductwork.

3. Cost

Mini-splits typically have a higher upfront cost per unit but lower installation costs without ducts. Great for individual rooms or additions.

Central air systems may be cheaper per square foot if you’re cooling an entire home and already have ducts in place.

4. Appearance

Mini-split units are visible inside the room, usually mounted high on a wall. Central air vents are less noticeable and integrated into ceilings or floors.

5. Maintenance

Both systems need regular maintenance, but ductless systems are easier to clean and maintain because there's no ductwork to inspect and seal.
