If you’re trying to cool your home without adding ductwork, you’ve probably seen both terms: “ductless AC” and “mini-split.” They sound similar — and often get used interchangeably — but they’re not the same. Here’s what you actually need to know, in plain English.

Ductless AC vs. Mini-Split: The Real Difference

Let’s cut through the confusion.

In short:

All mini-splits are ductless ACs, but not all ductless ACs are mini-splits.

Common Types of Ductless AC Systems

Here’s how they stack up:

1. Portable Ductless ACs

• Plug-in units you roll from room to room
  
• Often vent out a window
  
• Low cost, but loud and not very efficient
  
• Good short-term solution, not ideal for whole-home comfort
  

2. Window or Wall-Mounted ACs (non-split)

• Installed in windows or sleeves in the wall
  
• Fully self-contained units
  
• More permanent than portable ACs
  
• No zoning, moderate efficiency
  

3. Mini-Split Ductless Systems

• Best long-term option for cooling without ducts
  
• High-efficiency outdoor unit + indoor wall-mounted unit
  
• Quiet, clean, and customizable (room-by-room comfort)
  
• Can heat as well as cool
  
• Most popular system we install across Vail, Aspen, and Glenwood
  

Why Mini-Splits Are the Most Popular Ductless Option

Most of our customers asking for “ductless AC” actually want a mini-split — they just don’t know the name yet.

Here’s why mini-splits win:

 Energy-efficient (uses inverter technology)
 Zoned cooling: set different temps in different rooms
 Out of the way: sleek, modern wall-mounted design = less obtrusive than other units
 Quiet — seriously, whisper-level
 Versatile: great for additions, retrofits, or homes without ductwork

When Would You Choose Something Else?

Choose a different ductless AC system (not a mini-split) if:

• You’re renting and can’t install a permanent system
  
• You need a short-term solution or budget fix
  
• You’re only cooling a very small space (like a garage occasionally)
  

But if you want long-term comfort, low bills, and year-round use — a mini-split is your best move.

What About Cooling Power?

• A portable unit might cool 100–300 sq ft
  
• A through-the-wall unit could do 400–500 sq ft
  
• A ductless mini-split? Can cool one room or your entire home (multi-zone)
  

Ductless Mini-Split Costs in Colorado

For homeowners in Vail, Eagle, and surrounding areas, here’s what we typically install:

• Single-zone system (1 room):
   $3,500–$6,000
  
  
• Multi-zone system (2–4 rooms):

We also handle rebates and energy incentives, which can knock hundreds off your cost.

One More Thing: Heating Too? Yup.

Mini-splits don’t just cool — they heat too.
That means one system, year-round comfort, no ductwork required. Perfect for mountain weather swings.

Bottom Line: Which One’s Better?

Our take?
If you’re serious about comfort and efficiency, mini-splits are hands-down the better choice.
