Ductless Mini-Split Installation for Wilmette homes
Many Wilmette homes have grown or been finished in ways their original HVAC wasn't sized for, leaving certain rooms stubbornly hot or cold. Extending strained ductwork into those spaces rarely works well; a ductless mini-split conditions them directly instead, with a compact head in each zone fed from a single outdoor unit and controlled independently. You cool the sunroom on a July afternoon without overworking the whole-house system.
Because the system is a heat pump, it heats as well as cools, and a cold-climate mini-split that clears the ENERGY STAR floor qualifies for ComEd's heat-pump rebate. We size the heads to the actual rooms, route line sets cleanly, and place the outdoor unit where it won't intrude on the yard. Licensed, insured installers register the warranty, and hand off the incentive documentation.

Why Wilmette homes need replacement planning
Wilmette mixes century-old lakefront homes with solid mid-century construction, so replacement projects range from boiler and radiator systems in the older east side to furnace-and-AC changeouts in postwar homes further west. Many homes added central air decades ago and are now on their second or third system.
