Some rooms were never part of the plan. A converted garage, a casita, a room addition, or a home with no existing ductwork all have the same problem: running new ducts is expensive, invasive, or sometimes impossible. A ductless mini-split solves it with its own dedicated indoor and outdoor units, cooling that space without touching your main system.

Good fits for a mini-split

  • Room additions and converted garages
  • Casitas and guest quarters
  • Homes without existing ductwork
  • Sunrooms, workshops, and home offices that run hot
  • Zoned comfort — cool one room without running the whole system

Our process

How we size and install a mini-split

01

Load calculation

We calculate the cooling load for the specific space, not a rule-of-thumb estimate based on square footage alone.

02

Pre-measurement

We check wall access, electrical capacity, and where the line set will run before we quote the job.

03

Installation

We mount the indoor and outdoor units and run the line set cleanly, with attention to how it looks as well as how it performs.

04

Third-party verification

The completed installation is independently checked against the original quote and manufacturer specifications.

05

Written guarantee

Qualified mini-split installations are backed by our 1-year money-back guarantee, the same as any qualified full-system replacement.
