ADU and Casita Mini Split Installation
Guest houses rarely have ducts. A mini split gives them full independent comfort.
ADUs almost never share the main ductwork.
A single-zone system usually covers one ADU.
We give a fixed written quote after a free visit.
Most ADU installs finish in one day.
Why a mini split suits this space
- Full independence from the main house.
- Separate control for your guest or tenant.
- Heating and cooling from one unit.
- A strong selling point for rentals.
Why ADUs suit ductless
Extending ducts to a detached building is costly.
It often means trenching and major work.
A mini split needs only its own outdoor unit.
Sizing an ADU
Most casitas run 400 to 800 sq ft.
That usually means a 1 ton or 2 ton unit.
Open plan layouts often need just one head.
