At Sub Zero Temp Control here in Vancouver, WA, we get this question a lot: “Should I go with a ducted mini split or a ductless system?” The truth is, both options have their benefits. But depending on your home’s layout and your comfort goals, one might be better than the other. So let’s break down the difference.
What Is a Ducted Mini Split System?
A ducted mini split combines the efficiency of a ductless system with the look and feel of traditional ducted HVAC. Instead of bulky ductwork running throughout the home, these systems use short-run ducts, typically concealed in attics, crawlspaces, or drop ceilings.
Because the air handler is hidden, you still get that clean look on your walls or ceilings—no wall-mounted units in sight. It’s a great fit for homeowners who want a more streamlined design without sacrificing efficiency.
How Does a Ductless System Work?
While a ducted mini split uses small ducts to distribute air, ductless systems skip ducts entirely. Each zone has its own indoor unit mounted on the wall, connected to an outdoor compressor. These units allow you to heat or cool specific rooms independently.
This type of system is ideal for additions, garages, or homes without existing ductwork. Plus, installation is typically quicker and less invasive than ducted alternatives.
Ducted Mini Split vs Ductless: Which Is More Efficient?
Both systems are extremely efficient. However, ductless systems have a slight edge because there’s no energy loss through ductwork. That said, a ducted mini split still outperforms traditional HVAC systems and works beautifully in homes with tight, well-designed duct layouts.
If your home already has short ducts or you want a more concealed system, going with a ducted mini split might be the smarter choice.
Comfort and Aesthetics Matter
If you don’t love the look of wall-mounted units in every room, a ducted mini split gives you the comfort of zoned control with a more discreet appearance. This is especially appealing in bedrooms or common areas where aesthetics matter.
On the other hand, if you’re adding a sunroom or converting a garage, ductless is fast, easy, and highly flexible.
Noise Levels: A Quick Comparison
Ductless and ducted mini splits are both quieter than traditional HVAC. Still, ducted mini split systems often have their air handlers tucked away, making them virtually silent in living spaces.
That said, modern ductless systems are impressively quiet too—many homeowners barely notice them running.
Installation Considerations
Installing a ducted system usually takes a bit more planning than a ductless unit. You’ll need some attic, crawlspace, or ceiling space to run ducts. However, if your home allows for it, the extra effort pays off in comfort and appearance.
Ductless systems, on the other hand, are often installed in just a day or two. They’re especially useful in spaces where ducts would be impractical or too expensive to add.
Which One Costs More?
While prices vary, a ducted mini split system tends to cost a bit more upfront than a ductless one. This is mainly due to the added ductwork and installation time. But for homeowners who want centralized control and hidden air handlers, the investment can be well worth it.
Ductless systems offer savings on both equipment and installation. However, multiple wall units can add up in price, especially for larger homes.
Maintenance Needs
Here’s the good news—both systems are pretty low-maintenance. With a ducted mini split, you’ll need to keep ducts clean and filters changed. Ductless systems require regular filter cleaning as well, especially if you have pets.
Either way, routine maintenance ensures your system runs efficiently and lasts for years.
So, Which System Should You Choose?
It really comes down to your priorities. If you want sleek design and already have a duct path available, a ducted system is an excellent solution. If flexibility and fast installation matter more, ductless may be the way to go.
