Multi-Zone Mini-Split Installation in Tucson, AZ
Every room on its own setting. No ductwork required.
Multi-zone is priced per indoor head, about $5,000 each, and it is what most of our mini-split customers choose. Each head is sized to a measured room load, not guessed from square footage.
- About $5,000 per indoor head
- Room-by-room Manual J sizing
- TEP participating contractor
A multi-zone mini-split connects several indoor heads to one outdoor unit. Each head has its own setting, so the bedroom can sit where you want it while the guest room stays off. There are no ducts to run, no attic crawl, and no chase cut through finished ceilings.
Most of the mini-split systems we install are multi-zone. Single-zone covers one space and starts at $5,500. Multi-zone is for the home that needs more than one room handled, and it is priced per indoor head, about $5,000 each.
Bigger homes use more than one outdoor unit. Our six-head job in Tucson used three. See that install.

Our process
How we design a multi-zone system
01
Manual J, room by room
We run a Manual J load calculation in ACCA Manual J software. You get a separate heating and cooling load for every room that gets a head.
02
Match heads to rooms
Each indoor head is sized to its measured room load. Then we pick the outdoor unit or units that carry those heads together.
03
Pre-measurement
We check wall access, electrical capacity and where every line set will run before install day, so there are no surprises on the wall.
04
Installation
We mount the heads and the outdoor unit, run the line sets in covers and route the condensate drains.
05
Quality-control visit
We record operating readings. A separate quality-control visit runs the full checklist, and the equipment warranties get registered.
06
Third-party verification
The completed installation is independently checked against the original quote and manufacturer specifications.
07
Backed in writing
Every mini-split install is backed by our written warranty. See the warranty details.
Proof: six heads, three outdoor units, one Tucson home
The homeowner wanted off gas and said the old central air never worked right. We removed the five-ton split system and installed three ductless heat pump systems with six wall-mounted indoor heads.
Our comfort advisor ran a room-by-room Manual J, and each head was matched to a measured room load. The page shows the room-load report, the planned line-set routes and the finished work. See the install.
