Ducted vs. Ductless AC: Which Is Better for Texas Homes?

Choosing between a ducted (central air) and ductless (mini split) air conditioning system is one of the most common HVAC decisions facing Texas homeowners—especially with the state’s sweltering summers and varied housing styles. While both systems can keep you cool, the right choice depends on your home's structure, energy goals, and comfort preferences.

In this guide, we’ll break down the pros, cons, and ideal use cases of each system so you can make a confident decision about which cooling option is best for your Texas home.

What’s the Difference Between Ducted and Ductless AC?

Let’s start with a quick breakdown:

• Ducted AC (Central Air): Uses a single indoor unit (typically in an attic or closet) connected to ductwork that runs throughout the house, delivering air via vents.
  
  
• Ductless AC (Mini Split): Has one or more wall-mounted indoor units, each connected to an outdoor condenser. No ductwork is required; air is delivered directly into the room.
  
  

Both systems use the same cooling principles but differ in air delivery, installation, and zoning capabilities.

Pros and Cons of Ducted AC (Central Air)

✅ Pros

1. Aesthetically Discreet
Vents blend seamlessly into ceilings or floors, unlike the visible indoor heads of ductless systems.

2. Whole-Home Comfort
Ideal for evenly cooling large homes with many rooms, especially those that already have ductwork in place.

3. Better Air Filtration Options
Central systems can integrate with advanced whole-home air purification and humidity control systems, improving indoor air quality.

4. Lower Upfront Cost (If Ducts Exist)
If your home already has ductwork, central AC installation is usually less expensive than installing multiple ductless units.

❌ Cons

1. Less Efficient
Duct losses account for up to 30% of energy consumption in some homes, according to the U.S. Department of Energy.

2. Higher Utility Bills
Cooling your whole home—even unused rooms—leads to unnecessary energy usage.

3. Costly Duct Repairs or Installation
Homes without ductwork could pay $10,000–$18,000 to retrofit ducts, making this option expensive for older homes.

Pros and Cons of Ductless AC (Mini Splits)

✅ Pros

1. High Efficiency
Mini splits can reach up to 35 SEER2, far surpassing standard central systems. Less energy is lost since there are no ducts.

2. Zoned Comfort
Control the temperature of each room individually. Great for families with different preferences or underused rooms.

3. Ideal for Older or Add-On Homes
Perfect for homes without ductwork, garages, sunrooms, or recent additions.

4. Quick, Non-Invasive Installation
Only requires a small hole for refrigerant lines—no tearing into walls for ductwork.

❌ Cons

1. Higher Upfront Costs
Installing multiple indoor units for whole-home coverage can add up quickly.

2. Visible Indoor Units
Wall-mounted heads may clash with some interior aesthetics.

3. More Frequent Maintenance
Filters need cleaning every 2–4 weeks. Ignoring this can reduce performance and efficiency.

4. Limited Air Filtration
Most mini splits have basic filtration compared to ducted systems that support HEPA and whole-home purifiers.

Which Is Better for Texas Homes?

Consider Ducted AC If:

• Your home already has ductwork in good condition.
  
  
• You want hidden equipment and whole-home coverage.
  
  
• Indoor air quality is a major concern.
  
  

Explore Air Techs' central AC installation services or schedule an HVAC consultation to evaluate your existing ductwork.

Consider Ductless AC If:

• Your home lacks ductwork (common in older Texas homes).
  
  
• You want zoned cooling and lower monthly energy bills.
  
  
• You’re adding cooling to a garage, attic, or addition.

Can You Use Both Systems Together?

Absolutely. Many Texas homeowners use a hybrid approach—central air for the main living areas and ductless mini splits for problem zones like upstairs bedrooms or sunrooms. This gives you the best of both worlds: broad coverage with energy-saving precision.

If you're unsure which combination is right, the team at Air Techs Heating & Cooling can help evaluate your needs and provide a tailored solution.

Final Thoughts: Mini Split vs. Central Air

There’s no one-size-fits-all answer when it comes to choosing between ducted and ductless air conditioning. Central air is often the best fit for homes with existing ducts and larger square footage. Ductless mini splits shine in older homes, home additions, and energy-conscious households looking for zone control.
