A professionally installed mini split in the United States costs about $2,000 to $6,000 for one zone, $5,000 to $10,000 for two or three zones and $10,000 to $18,000 or more for four or more zones, according to Filterbuy’s 2026 national cost guide. Where a Los Angeles project lands inside those ranges comes down to six things: how many rooms you condition, the style of indoor unit, how far the refrigerant lines run, what your electrical panel can carry, which city issues the permit and which utility pays the rebate.
Key takeaways
- Published national ranges run from $2,000 for a basic single zone to $18,000 or more for a whole home.
- Each added zone adds roughly $2,000 to $7,000 in the same guide.
- Dr. Ductless prices an installation after a free in-home consultation, because the number depends on the house.
- Our service prices are fixed: $189 for a diagnostic visit and $199 to clean the first indoor unit.
- Rebate eligibility depends on whether your address is served by LADWP or Southern California Edison.
How much does it cost to install a mini split?
The installed price is set mostly by the number of zones. A zone is one indoor unit with its own temperature setting. These are the ranges Filterbuy publishes for professional installation in 2026.
| System | Published installed range |
|---|---|
| 1 zone | $2,000 to $6,000 |
| 2 zones | $5,000 to $8,000 |
| 3 zones | $7,000 to $12,000 |
| 4 or more zones | $10,000 to $18,000 or more |
The same guide breaks a single zone down by capacity.
| Single-zone size | Published installed range |
|---|---|
| 6,000 to 9,000 BTU | $2,500 to $4,200 |
| 12,000 BTU | $3,500 to $5,000 |
| 18,000 BTU | $4,500 to $6,500 |
| 24,000 BTU and up | $5,500 to $9,000 |
Read these as national context. They are one publisher’s figures, not a Dr. Ductless price list. Your price is set after a technician has seen the rooms, the walls and the electrical panel.
Six things that move a Los Angeles mini split quote
Two houses on the same street can get quotes thousands of dollars apart for the same number of rooms. These are the reasons.
- Number of zones. Every added indoor unit adds equipment, a line set and labor. Filterbuy budgets $2,000 to $7,000 for each one.
- Indoor unit style. A wall-mounted unit is the least expensive to install. Ceiling cassettes and concealed ducted units cost more because they are built into the ceiling.
- Line set length and route. A back-to-back install on a single-story stucco house is the simple case. A second-floor bedroom, a plaster wall in a 1920s bungalow or a long run around the house adds time and material.
- Electrical. Every system needs a dedicated circuit and a disconnect at the outdoor unit. If the panel has no room, Filterbuy puts a panel upgrade at $500 to $2,000 or more. Our post on outdated electrical panels explains what to look for.
- Permits. In the City of Los Angeles, the Department of Building and Safety requires a mechanical permit to install or change a heating or cooling system. Other cities issue their own. Filterbuy lists permit costs at $100 to $400.
- Brand and coastal protection. Filterbuy places Mitsubishi in its premium tier. Homes near the ocean may also need corrosion protection on the coils.
What a mini split quote should include
A low number often leaves something out. Before you compare quotes, check that each one covers the same work.
- A load calculation for each room. ENERGY STAR says a contractor should verify sizing with a Manual J calculation, because an oversized or undersized system performs poorly.
- The model numbers of the indoor and outdoor units
- The line set, the wall penetration and the exterior line cover
- The dedicated circuit and the outdoor disconnect
- The condensate drain, and a pump if the water cannot drain by gravity
- The permit and the inspection
- Removal of the equipment being replaced
How rebates and financing change the price
In Los Angeles, the rebate you can claim depends on which utility serves your address, because LADWP and Southern California Edison run separate heat pump programs. The rules and amounts change during the year, so check the current terms on our LADWP Electrification Program and SCE heat pump rebate pages. For the balance, see our financing options.
What mini split repair and cleaning cost
Service work is priced differently from installation, and Dr. Ductless publishes those prices.
| Service | Dr. Ductless price |
|---|---|
| Diagnostic visit | $189, credited toward the repair you approve |
| Cleaning, first indoor unit | $199 |
| Cleaning, each additional indoor unit | $59.99 |
| Cleaning a two-unit system | $258.99 |
| Cleaning a three-unit system | $318.98 |

Is a mini split cheaper than central air?
It usually is in a house with no ducts, because there is no ductwork to build. In a house that already has good ducts, ENERGY STAR notes that a ducted heat pump may be the better fit. Our comparison of ductless and central HVAC for Los Angeles homes walks through both cases.
Frequently asked questions
How much does it cost to install a mini split in a 1,000 square foot house?
It depends on how many rooms need their own unit. In Filterbuy’s 2026 guide, a two or three-zone system runs $5,000 to $10,000 installed. An open-plan space that one larger unit can serve falls nearer the single-zone range for an 18,000 BTU system, $4,500 to $6,500.
How much does a Mitsubishi mini split cost installed?
Filterbuy’s 2026 guide places Mitsubishi in its premium tier, at up to $7,800 or more per zone installed. The exact figure depends on the model, the number of zones and the installation conditions in your home.
Is the estimate free?
Yes. Dr. Ductless provides a free in-home consultation for new installations. Repair visits are different: a diagnostic visit is $189, credited toward the repair you approve.
Do I need a permit to install a mini split in Los Angeles?
Yes. In the City of Los Angeles, the Department of Building and Safety requires a mechanical permit to install or change a heating or cooling system. Other cities in Los Angeles County issue their own permits.
