Ductless systems
Mini-split installation
Mini-splits can solve room-by-room problems in a house without ducts, but head placement, condensate routing, line-set installation, controls, and low-load behavior determine whether the result is quiet and comfortable.

When a mini-split is worth planning
- A house, addition, or camelback has no ducts, or the ducts are not worth keeping.
- One room or floor never cools with the system you have.
- A proposed layout needs room loads and head placement checked.
- You have a quote and want to know what it leaves out.
The approach
Plan the rooms before the equipment
- 1
Work out each room’s load and exposure before choosing equipment sizes.
- 2
Write down room loads, equipment combinations, line routes, drains, power, controls, and service access.
- 3
Check where the outdoor unit can go under city zoning and, in a historic district, HDLC or Vieux Carré review.
- 4
Confirm every multi-zone combination against manufacturer data.
A mini-split has no ducts; each indoor head cools just its own room or zone.
What to expect
A plan someone can check
Exact equipment match
Multi-zone combinations must be supported by manufacturer data.
Drainage is designed
Condensate routing and maintenance access are part of the installation.
No square-foot shortcut
Each room and exposure affects selection and placement.
Sources and standards
The approach has a paper trail.
