Ductless Mini-Split Installation for Northbrook homes
The classic Northbrook mini-split job is the room the central system can't balance: a space added over the garage on a long duct run, a finished lower level, a converted three-season room. Rather than re-engineering the whole-house ductwork to fix one zone, a ductless mini-split conditions that room directly with its own head and thermostat, fed from a compact outdoor unit. It's the efficient, targeted fix for a common comfort complaint.
Because a mini-split is a heat pump, it both heats and cools, and a qualifying cold-climate model meeting the ENERGY STAR floor can earn ComEd's heat-pump rebate. We size the head to the space, route the line set cleanly, and place the outdoor unit where it won't intrude. Licensed, insured installers register the warranty, and walk you through the incentives the unit earns.
