Ductless mini-split installation in Los Angeles
A ductless mini-split is priced by zone in Los Angeles: published at $4,000–$7,500 for one indoor head and $15,000–$20,000 for four, in 2026. It is the usual answer for houses, condos and additions with no ducts, and it earns LADWP's highest heat pump rebate: up to $2,500 per ton.

At a glance
What a mini-split installation includes
One outdoor unit; one indoor head per zone, on a wall or ceiling or concealed in a cassette; a refrigerant line set and condensate drain from each head, run through the wall in a covered channel; a dedicated electrical circuit; and a controller for each zone.
There are no ducts, so there is no duct leakage test. Most ductless units are heat pumps that also heat; check the model, because that is what makes the LADWP rebate available.
Mini-split cost by number of zones
| Zones | Typical use | Published range | Sources |
|---|---|---|---|
| 1 zone | One room, ADU or addition | $4,000–$7,500 | E & A Mechanical, HVACProjectCost |
| 2 zones | Bedroom plus living area | $9,000–$12,500 | E & A Mechanical; least settled |
| 3 zones | Small house or large condo | $12,000–$16,500 | E & A Mechanical; least settled |
| 4 zones | Most of a house | $15,000–$20,000 | E & A Mechanical; least settled |
A long refrigerant run adds $300–$1,500 (Reliable H&A, E & A Mechanical). A new circuit or panel upgrade, if needed, is published at $2,000–$7,500 for the panel. Full method: cost guide.
Mini-split vs central air in a house with no ducts
Ductless mini-split
- Priced per zone: $4,000–$7,500 for one, $15,000–$20,000 for four
- No attic or crawlspace duct run
- Each room set separately
- LADWP rebate up to $2,500 per ton
- Indoor heads are visible on the wall
Central air with new ducts
- 3-ton system $8,000–$16,000 plus ducts $3,500–$8,000
- Ducts need attic or crawlspace room
- One thermostat for the house
- A ducted heat pump earns up to $1,250 per ton from LADWP
- Equipment hidden; only registers show
Older houses face this choice most often. See AC for older LA homes for the retrofit steps and costs.
Where a mini-split fits best in LA housing
- Craftsman and Spanish-style houses heated by wall or floor furnaces, where new ducts would mean opening plaster ceilings.
- Condos and apartments with no shared ducts, if the HOA allows an outdoor unit.
- ADUs, garage conversions and additions too far from the main system to extend ducts (see cooling an ADU, garage conversion or addition). Note that LADWP's rebate excludes ADUs.
- One hot room, such as a west-facing bedroom or a converted attic, in a house that is otherwise comfortable.
How many zones do you need?
A zone is one indoor head. Rooms that are open to each other can share a head; closed rooms with doors usually need their own. More heads mean more line sets, more wall penetrations and a larger outdoor unit.
A quick test
Walk the house and mark every room you want cool with the door shut. That count is the ceiling. Then ask each contractor to justify any head they add or remove from it.
The full decision, including when two single-zone systems beat one multi-zone, is in single-zone vs multi-zone mini-splits.
LADWP ductless rebate tiers
LADWP pays more per ton for ductless heat pumps than for ducted ones. A 1.5-ton single-zone unit in the lowest ductless tier earns $2,250; in the top tier, $3,750.
Ductless (mini-split, multi-split)
| Rated above | Per ton |
|---|---|
| 15.2 SEER2 and 7.8 HSPF2 | $1,500 |
| 16 SEER2 and 8.1 HSPF2 | $1,650 |
| 16.9 SEER2 and 8.3 HSPF2 | $1,800 |
| 17.8 SEER2 and 8.5 HSPF2 | $1,950 |
| 18.7 SEER2 and 8.7 HSPF2 | $2,100 |
| 19.6 SEER2 and 8.9 HSPF2 | $2,250 |
| 20.5 SEER2 and 9.1 HSPF2 | $2,500 |
LADWP customers only. Read on LADWP's Consumer Rebate Program page on 2026-10-20; tiers change, so check before you sign. Central, split, packaged, mini-split and multi-split heat pumps rated at least 15.2 SEER2 and 7.7 HSPF2. Packaged terminal heat pumps (PTHP) are not eligible. New construction and accessory dwelling units (ADUs) are not eligible. Apply after the equipment is bought and installed; the application must be postmarked within 12 months of the purchase date. The final approved Building and Safety permit is required.
ADUs are excluded
LADWP's page says accessory dwelling units and new construction are not eligible. A mini-split in a new ADU can be the right system and still earn no LADWP rebate.
Outdoor unit and line-set placement
The outdoor unit needs airflow, a level pad or wall bracket, and a route for the line set to each head. In dense neighborhoods the limits are setbacks, noise next to a neighbor's window, and HOA rules on balconies and roofs.
Agree the location, and how the line-set cover will look on the outside wall, before the quote is signed. Each extra foot of line set and each wall it crosses is labor.
How a mini-split job runs
- Room-by-room survey. Load per room, head locations, outdoor unit spot, electrical capacity.
- Written quote. Zone count, model numbers, SEER2 and HSPF2, line-set route, circuit, permit.
- HOA or landlord approval where the property has one.
- Permit from LADBS, LA County or your city.
- Install. Heads mounted, wall penetrations, line sets and drains, outdoor unit, circuit.
- Start-up and inspection. Refrigerant checks, controller set-up, final inspection; keep the paperwork for the rebate.
What to ask
- How many zones, and why that number for this floor plan?
- Where exactly will each head and the outdoor unit go, and how loud is the outdoor unit?
- Is the line set in a covered channel outside, or routed through the walls?
- Is it a heat pump, and which LADWP tier do its SEER2 and HSPF2 reach?
- Which permit office, and is the electrical circuit included? See the permit guide.
Compare zone counts and placement across quotes with the quote tool. Since 1 January 2025, work totaling $1,000 or more in labor and materials needs a CSLB license. Below that, an unlicensed person may do the job only if no building permit is needed and they hire no workers. An AC installation needs a permit, so it needs a license at any price.

Questions
How much does a ductless mini-split cost in Los Angeles?
A single-zone mini-split is published at $4,000–$7,500 installed in 2026, and four zones at $15,000–$20,000. HVACProjectCost prints multi-zone systems at $10,000–$18,000.
Does a mini-split need a permit?
Yes. It is a heat pump or AC installation like any other, with a refrigerant circuit and an electrical circuit. The permit comes from LADBS in the City of Los Angeles or from your city or county office.
Can one outdoor unit serve several rooms?
Yes, a multi-zone system runs several indoor heads from one outdoor unit. Each head adds cost, and the outdoor unit must be sized for the combined load. Rooms with very different loads may be better on separate single-zone systems.
How much is the LADWP rebate for a mini-split?
On LADWP's page on 2026-10-18, ductless mini-split and multi-split heat pumps earned $1,500 to $2,500 per ton, by efficiency tier, starting above 15.2 SEER2 and 7.8 HSPF2. ADUs and new construction are not eligible.
Is a mini-split cheaper than central air?
In a house without ducts, usually. One or two zones are published below a 3-ton central AC ($8,000–$16,000), and central air in that house would also need new ducts at $3,500–$8,000. Cooling a whole house with four or more heads narrows the gap.
Do mini-splits work for heating in Los Angeles?
Most ductless units sold now are heat pumps, which heat as well as cool, and LA winters are mild. Confirm the model is a heat pump and check its HSPF2 rating, which also decides the LADWP rebate tier.
How long does a mini-split installation take?
The on-site work for a single zone is usually short; each extra head adds line-set routing and wall work. Ask for the schedule in writing, including the permit and the final inspection, which add calendar days.
Can I install a mini-split myself?
Not legally for most homeowners. The job involves a refrigerant circuit and a dedicated electrical circuit and needs a permit. In California any job that needs a permit needs a CSLB-licensed contractor, whatever the price.
