Mini Split HVAC Systems for ADUs & Small Properties

Custom Setup & Consistent Comfort

Mini splits need the right placement and setup to perform well, especially in smaller spaces or additions. We make sure everything is installed correctly — from mounting the unit to running the lines and setting up the controls. If your current system isn’t doing the job, we’ll take a closer look and make adjustments that restore full performance. With the proper setup, mini splits offer consistent comfort without the bulk of traditional systems.

Clean Setup & Quiet, Even Performance

After setup, we test the mini split to make sure it heats and cools evenly, responds to controls, and runs quietly. We also check for signs of strain or leaks so you won’t run into trouble later. When a mini split is set up correctly, it works quietly in the background and keeps the space comfortable without much effort on your part.

Quiet Operation & Reliable Comfort

A properly installed mini split should work quietly and deliver steady comfort without needing much attention. We focus on the details during installation and take time to test performance before we leave. If you’re adding one to a new space or replacing an older unit, we’ll make sure it works the way it should.
