Ductless Mini Split Installation Cost in 2026

What Drives Mini Split Installation Cost Up or Down

Labor (30 to 50 percent of the total cost):

• Standard line set length: 25 feet included, each additional 10 feet adds $75 to $200
  
  

• Second story indoor unit placement: adds 1 to 2 hours of labor
  
  

• Ceiling cassette vs wall mount: adds $800 to $1,500 per zone

  
  

• Concealed / ducted mini split: adds $1,200 to $2,500 per zone
  
  

• Long concrete exterior wall drilling: adds $150 to $400 per penetration

A single zone ductless mini split costs $2,800 to $6,500 installed in 2026, with the national average around $4,200. Multi zone systems (2 to 5 indoor heads) run $6,500 to $15,000 depending on zone count, brand, and installation complexity.

Mini splits are one of the fastest growing HVAC categories across all of our service areas, driven by three things: they work great in homes without ductwork, they offer true zone by zone control, and they qualify for the federal heat pump tax credit.
