Ductless Mini Split Installation in Portland, ME
Ductless mini split installation puts a wall-mounted air handler in the room you want to condition and connects it to an outdoor compressor with refrigerant lines run through a small hole in the wall. There's no ductwork involved. It's a practical solution for older Portland homes without central air, sunroom additions, or rooms that your existing system can't adequately reach. The installation itself is a half-day to full-day job depending on where lines need to run.

How It Works
Our Process for Ductless Mini Split Installation
- 1
Site Assessment
We look at the room size, wall construction, outdoor compressor placement, and electrical panel capacity before sizing the unit.
- 2
Line Set Routing
We plan the cleanest path for refrigerant lines, drain line, and electrical from the indoor head to the outdoor unit.
- 3
Equipment Installation
Indoor head gets mounted, outdoor unit gets set on a pad or bracket, and lines get connected and insulated.
- 4
Startup and Commissioning
We pressurize the system, check for leaks, release refrigerant, and verify both heating and cooling operation before we leave.
Portland Context
Why this matters in Portland
A large portion of Portland's housing stock predates forced-air systems, which makes ductless the most practical path to whole-home comfort. We've installed mini splits in Victorians on Congress Street and cape-styles in Deering where running duct simply isn't feasible.
Straight Talk
About pricing & scope
Cost scales with how far the line set needs to run and whether the electrical panel needs a dedicated circuit added. Difficult routing — through finished walls or long exterior runs — takes more labor than a straightforward installation.
