What’s the Difference Between Central Air and Mini-Splits?
Central Air Conditioning
Central air systems use a large outdoor condenser unit connected to ducts that deliver cooled air through vents across the entire home. One central thermostat typically controls the temperature.
Ductless Mini-Split Systems
Mini-splits use one or more wall-mounted indoor units connected to an outdoor compressor. They don’t require ducts and allow you to cool individual rooms or “zones” with separate temperature controls.
Pros and Cons of Central Air vs Mini-Split Systems
| Feature | Central Air | Ductless Mini-Split |
|---|---|---|
| Installation Cost | Moderate to high (especially with ductwork) | Lower if no ducts are needed |
| Energy Efficiency | Good (with sealed ducts) | Excellent (no duct loss) |
| Zoned Cooling | Requires dampers or separate systems | Yes – each unit is independent |
| Aesthetic/Visibility | Fully hidden | Visible indoor wall units |
| Best For | Large homes with existing ductwork | Older homes, additions, individual rooms |
| Maintenance | Duct cleaning + filter replacement | Cleaning filters on each unit |
Factors to Consider When Choosing a Cooling System
Home Size and Layout
Central air works well for large, open-plan homes with existing ductwork. Ductless systems are ideal for homes without ducts, remodels, basements, or room additions.
Installation Cost
Installing central air may be more expensive if you need new or upgraded ductwork. Ductless systems avoid this, but each indoor unit adds to the total cost.
Energy Efficiency
Mini-splits are often more efficient due to the absence of duct losses and their variable-speed compressors.

Comfort Control
Mini-splits offer full control of temperatures in each zone. Central air can cool the whole house evenly, but unless zoned, it lacks room-by-room precision.
Aesthetic Preferences
If visual design is a concern, central air systems are virtually invisible. Mini-split units are visible, though modern units are sleek and unobtrusive.
Which System Is Better for Durham, NC Homes?
Durham’s hot, humid summers make energy efficiency and reliability a must. Older homes in the area often lack ductwork — making ductless systems a smart retrofit solution. Newer or already-ducted homes may benefit from central air if whole-house cooling is the goal.
If you’re looking for:
- Whole-home comfort – Central air may be better
- Room-by-room control and lower energy use – Ductless might win
