Ductless mini splits in Oakland
A ductless mini split heats and cools without ductwork. That makes it the natural fit for Oakland homes heated by wall heaters or floor furnaces. We size each system to the house and pull the City of Oakland permit.
Where a mini split fits
Oakland's older houses are exactly the homes ductless systems were made for.
- Craftsman bungalows and Victorians
No ducts and plaster walls. A small line set replaces a whole duct system.
- Homes heated by a wall heater or floor furnace
Replace the old unit, or add a mini split and keep the heater as backup.
- The room that never gets comfortable
A single indoor unit for a hot bedroom or a cold back room.
- Additions, converted garages and ADUs
Heat and cool new space without extending ducts.
- Hills homes with upper floors
Separate zones so the top floor stops running hotter than the rest.
How we install a mini split
We size the system with a room-by-room load calculation, not a guess from square footage.
We plan where the indoor units go, how the line set and condensate drain run, and whether the electrical panel can take the new circuit. You get a written price covering the equipment, the installation and the permit before anything is ordered.
One outdoor unit can serve one room or several. We explain the single-zone and multi-zone options for your layout in writing.
A mini split is a heat pump with no combustion, so it already meets the Bay Area 2029 zero-NOx rule.
