Ductless mini-split installation in San Diego County
Garage gym, ADU, converted office, that add-on the ducts never reached, or a whole house that never had ducts at all — mini-splits put quiet, efficient, zoned comfort exactly where you need it without opening up walls.
Where mini-splits shine
- ADUs and granny flats — the county is full of them, and they need their own comfort
- Garage conversions, home offices, and bonus rooms the central system ignores
- Older and rural homes without ductwork (common in Lakeside, Alpine, Jamul)
- Rooms that need their own thermostat — a hot west-facing bedroom, a nursery
- Homeowners who want heating AND cooling from one wall unit
What we do
We help you pick zones honestly — not every room needs a head, and oversizing a mini-split makes it short-cycle and underperform. Clean line-set routing, proper condensate, a real condenser pad, and a permit when the job requires one. Single-zone installs are usually done in a day.
What things actually cost
| Job | San Diego market range |
|---|---|
| Single zone, installed (San Diego market) | $3,000 – $6,500 |
| Dual zone | $7,000 – $10,500 |
| Whole-home multi-zone | $13,000 – $18,000+ |
These are the ranges San Diego homeowners actually pay across the market — not a quote. We price your exact job before any work starts, and the number doesn't move after.
Do I need one in every room?
Usually not. Open living areas share a head; bedrooms that matter get their own; hallways never do. A good zone plan costs thousands less than a head-in-every-room quote — which is exactly why some companies love the latter.
