Ductless mini split cost guide
Ductless mini split installation cost depends heavily on the number of zones, line-set length, wall access, electrical work, condensate routing, and whether the system is replacing or supplementing central HVAC.
Direct answer
$2,150 - $6,350

Start with design, not head count
A single-zone mini split serves one defined area with one indoor unit and one outdoor unit. A multi-zone system connects several indoor units to shared outdoor equipment. The second design can reduce outdoor-unit count, but it adds distribution, controls, routing, and room-by-room capacity decisions. That is why cost should be compared by a documented zone plan, not a flat price per head.
Closed bedrooms, separate floors, additions, and homes without ducts often create different zone layouts. Ask each contractor to price the same rooms, design temperatures, electrical assumptions, and finish-restoration scope.
Confirm the room load, dedicated circuit, outdoor-unit location, short line route, and gravity-drain path before accepting a one-zone price.
Compare one multi-zone system with more than one smaller system. Ask how minimum output and simultaneous loads affect comfort.
Require design-temperature capacity, backup-heat strategy, defrost assumptions, electrical capacity, and an explicit plan for rooms without a head.
| System | Range | Quote note |
|---|---|---|
| Ductless Mini Split | $2,150 - $6,350 | Useful for additions, older homes without ducts, or zoned comfort. |
| Heat Pump | $2,700 - $5,750 | Often costs more upfront, but can replace heating and cooling in one system. |
| Central Air | $2,500 - $5,300 | Best for homes with usable ductwork and separate heating. |
| Home size | Tonnage | Range |
|---|---|---|
| 1,200 sq ft | 2 tons | $1,950 - $5,900 |
| 1,600 sq ft | 3 tons | $2,150 - $6,350 |
| 2,000 sq ft | 4 tons | $2,250 - $6,800 |
| 2,400 sq ft | 5 tons | $2,400 - $7,250 |
| 3,000 sq ft | 5 tons | $2,400 - $7,250 |
Estimate a planning range with the calculator.
Collect at least three itemized local bids.
Compare scope before comparing final price.
Use the planning range above as a benchmark, then compare at least three itemized bids with equivalent equipment, sizing, ductwork, permit, startup, and warranty scope.

A single-zone ductless system can be cheaper than adding ducts, but multi-zone projects can approach or exceed central system pricing depending on layout and electrical work.
Zone count depends on room layout, open areas, insulation, sun exposure, and comfort goals. Ask contractors to explain room-by-room sizing rather than quoting only by square footage.
It should include indoor head count, outdoor unit model, line-set routing, electrical scope, condensate plan, wall penetrations, startup, warranty, and permit handling.
A one-zone project often plans around $3,500-$8,000 installed before major electrical service work, long concealed line routes, difficult access, premium cold-climate equipment, or wall repair. Compare itemized local bids for the exact room load and route.
No. One outdoor unit reduces equipment count, while two systems can improve redundancy and sometimes fit low-load operation or routing better. Ask for both designs when the project has several closed rooms or separate floors.
Permit requirements vary by jurisdiction and scope. Mechanical and electrical work commonly require permits or inspections. Ask the contractor to list each required permit and who is responsible for closing it.
