What Is a Ductless Air Conditioning System?

A ductless mini-split system consists of an outdoor unit and one or more indoor air handlers mounted on walls or ceilings. These systems do not require ductwork, making them a convenient option for homes without existing ducts or for room-specific cooling needs.

Pros of Ductless AC:

Flexible Installation: Ideal for homes without existing ductwork or room additions.
Energy Efficiency: No duct losses mean higher efficiency and lower energy bills.
Zoned Cooling: Each indoor unit operates independently, allowing customized temperature settings.
Quiet Operation: Ductless systems are generally quieter than central air systems.

Cons of Ductless AC:

Higher Upfront Cost: The initial investment is typically higher per unit compared to central air systems.
Aesthetic Concerns: The indoor air handlers are visible and may not blend with home decor.
Limited Coverage: A single unit may not be sufficient to cool larger homes efficiently.

What Is a Central Air Conditioning System?

A central air conditioning system cools an entire home using a network of ducts to distribute cooled air from a single outdoor unit connected to an indoor evaporator coil.

Pros of Central AC:

Whole-Home Cooling: Effectively cools large spaces with a single system.
Inconspicuous Design: Air is delivered through vents, maintaining a cleaner aesthetic.
Increased Home Value: Homes with central AC are often more appealing to buyers.

Cons of Central AC:

Higher Energy Costs: Ductwork losses can reduce efficiency, especially in older homes.
More Maintenance: Ductwork requires periodic cleaning and maintenance.
Installation Complexity: Requires professional installation and may not be feasible for homes without existing ductwork.

Key Factors to Consider When Choosing Between Ductless vs. Central Air Conditioning

When choosing the best air conditioner between ductless vs. central air conditioning, there are some important factors to keep in mind. These include:

1. Home Size and Layout

A ductless system is best for smaller homes, single rooms, or homes without ductwork.
Central AC is more suitable for larger homes requiring consistent cooling in all rooms.

2. Energy Efficiency

Ductless mini-splits tend to be more energy-efficient since they avoid energy losses from ductwork.
Central AC systems with high SEER (Seasonal Energy Efficiency Ratio) ratings can also be efficient but require proper duct maintenance.

3. Installation Cost and Maintenance

Ductless AC has a higher per-unit cost but lower installation expenses in homes without ducts.
Central AC has higher installation costs, especially if ducts need repairs or modifications.

4. Aesthetics and Space Considerations

Ductless systems require visible indoor units, which may not blend well with all home designs.
Central AC systems use vents, keeping the system out of sight.

FAQs About Ductless vs. Central Air Conditioning

Which is more cost-effective in the long run?

When comparing ductless vs. central air conditioning, cost is an important consideration. Ductless ACs often provide better energy savings due to zoned cooling, but central ACs can be cost-effective for larger homes when well-maintained.

Is ductless AC good for humid climates like St. Louis?

Yes, ductless systems effectively remove humidity, but central ACs with dehumidification features may perform better for whole-home humidity control.

Can I switch from central AC to ductless?

Yes, many homeowners in St. Louis opt for ductless systems when replacing outdated central AC units, especially in homes without adequate ductwork.
