Mini-Split Installation in Roseville, CA
Roseville's rapid growth in neighborhoods like Fiddyment Ranch has produced thousands of new homes — many with finished garages, bonus rooms, or backyard casitas that the central HVAC system simply doesn't reach. A ductless mini-split solves that problem without tearing into walls or adding ductwork. With summer temperatures regularly topping 100°F, adding targeted cooling to an unconditioned space in Roseville isn't a luxury — it's a necessity.
Our Mini-Split Install Process in Roseville
Site Assessment
Andrew visits your home to evaluate the room or rooms you want to condition, assess your electrical panel capacity, and identify the best placement for both the indoor air handler and the outdoor compressor unit.
Unit Selection
We calculate the correct BTU size for your space based on square footage, insulation, sun exposure, and ceiling height. We also determine whether a single-zone or multi-zone system best fits your needs and budget.
Professional Installation
Our technicians mount the indoor air handler at the optimal wall or ceiling position, install the outdoor compressor on a stable pad, and run properly insulated refrigerant lines through the wall with a clean, finished appearance.
Electrical Connection
We install a dedicated circuit breaker and run appropriately sized wiring to meet code requirements for your new system, ensuring safe, reliable power delivery to both the indoor and outdoor units.
System Startup & Training
We pressure-test and leak-check the refrigerant lines, power up the system, and verify correct operation in cooling, heating, fan, and dehumidification modes. We walk you through the remote control and app features so you get full value from day one.
