Ductless mini splits in Stockton
A ductless mini split cools and heats one room or zone without ducts. It is the usual answer for a garage conversion, a backyard ADU, an addition, or a bedroom the central system never reaches. Fixr puts a typical installation at $4,577 to $8,328.
When a mini split is the right call
- A converted garage or a new accessory dwelling unit with no ductwork.
- An upstairs bedroom that runs several degrees hotter than the rest of the house on July afternoons.
- An older Lincoln Village or central Stockton house where running new ducts would mean opening walls.
- A room you want to keep cool without running the whole house system during PG&E's peak hours.
When it is not the right call: if the whole house is hot and the central system is simply failing, a single mini split won't fix that. Get the central system looked at first. AC repair.
What it costs
Fixr lists a ductless installation at $4,577 to $8,328, with a $6,357 average. A multi-zone system with several indoor heads costs more. Electrical work to add a circuit is a common extra. Mini splits are heat pumps, so they heat in winter too.
What to ask
- Is it sized for the room from a load calculation, or by square footage alone?
- Where will the line set and condensate drain run, and what will it look like outside?
- Is a permit included? California treats a new system as permitted work.
- Which refrigerant does the quoted unit use?
- What is the warranty on the compressor, the parts and the labor?
