We get it. That old clunker of an air conditioner just isn’t cutting it anymore.
Texas summers are no joke—you need a reliable system to keep your home cool and comfortable. If you’re shopping for a new AC, you might be torn between central air conditioning and a ductless mini split system.
Not sure what a mini split is or which option is best? No worries. The right choice depends entirely on your home, preferences, and budget.
Below, we’ll break down both systems to help you decide.
Central Air Conditioning
A central air conditioning system cools your home from a single location, distributing air to each room through ductwork. Fans push cold air into every space, and once the air warms, it circulates back through the ducts to be cooled again.
Advantages of Central Air Conditioners
Cool Temperatures
New central AC systems efficiently cool your entire house and remove humidity for consistent comfort across every room.
Lower Installation Costs
While prices vary depending on your home, central air installation is generally less expensive than installing multiple mini split units.
Less Visible Equipment
Central systems rely only on registers inside the home and one outdoor unit. Mini splits require wall or ceiling mounted units in each room, which some homeowners find less appealing aesthetically.
Disadvantages of Central Air Conditioners
Existing Ductwork Required
Homes without ducts—especially older homes—may require costly installation to support central AC.
Maintenance Needs
Dirty ducts can reduce air quality and airflow. Over time, ducts may collect dust, mold, mildew, or even become a nesting place for pests.
Higher Operating Costs
Air can escape through cracks or holes in aging ductwork, forcing your AC to work harder and increasing energy bills.
One Temperature for the Whole House
Central AC cools every room—used or unused—leading to unnecessary energy consumption and higher costs.
Ductless Mini Split Systems
Ductless mini split systems don’t use ductwork. They consist of an outdoor compressor and indoor air handlers. Coolant travels between both units, removing heat from inside and releasing it outdoors.
Advantages of Mini Splits
No Ductwork Needed
Great for homes without ducts. You also avoid concerns like duct leaks, dust buildup, or duct cleaning.
Room-by-Room Control
Heat or cool only the rooms you use. This provides greater comfort and may lower your energy bill.
Quieter Operation
Because the compressor is outside, mini splits are quieter indoors. You’ll mainly hear a gentle fan noise.
Disadvantages of Mini Splits
Higher Upfront Cost
Mini splits can cost about 30 percent more than a central AC system. For some homeowners, this may exceed the budget.
Home Size Limitations
Mini splits work best in smaller or medium sized homes. Larger homes may require multiple zones, which increases cost and complexity.
Visible Indoor Units
Mini split air handlers are mounted on the wall or ceiling and remain in view. Some homeowners prefer the minimal look of central air registers.
