Mini-Split Installation
Ductless heating and cooling for the rooms your central system never could reach — sized right, installed clean, done in a day.
Ductless mini-splits solve the rooms your central system never could: the bonus room over the garage, the finished basement, the garage gym, the sunroom that bakes every July, and the older Boise homes with no ductwork at all. We install single-zone and multi-zone systems — one outdoor unit driving up to five indoor heads — including cold-climate models that heat efficiently well below zero. Every quote starts with a room-by-room load calculation so each head is sized to its space; an oversized head short-cycles and leaves the room clammy, which is the number-one complaint we see from bargain installs. Our crews route refrigerant lines in tidy, paintable line-hide, pull the electrical permit, vacuum and pressure-test the line set to manufacturer spec, and commission the system with measured readings rather than a gauge-and-guess charge. Most single-zone installations are finished in one day, multi-zone in two, and every job ends with a full walkthrough of the remote and app controls before we leave.

Common questions
Do mini-splits really heat in an Idaho winter?
Cold-climate models do — they hold their rated heating output well below 0°F, which covers nearly every night the Treasure Valley sees. For a detached shop or a bonus room, a properly sized cold-climate head is often the most efficient heat available. We'll tell you honestly if your application calls for a backup heat source, but most don't.
How much does a mini-split cost installed?
Most of our single-zone installations land between $4,200 and $6,500 depending on capacity, line-set length, and electrical work; multi-zone systems are quoted per head. Your written estimate breaks out equipment, electrical, and labor separately, and it's free — we don't charge to come measure.
Does every room need its own indoor head?
No, and over-heading is the most common mistake we're asked to fix. An open living/kitchen area usually shares one head; bedrooms that keep doors closed usually want their own. We map airflow room by room during the estimate so you buy the zones you need and not one more.
