Much of the North Shore - Winnetka, Wilmette, Kenilworth, Highland Park - runs on hot-water or steam boilers, many of them decades old and long since converted from their original fuel. We replace aging boilers with modern, safer, more efficient units, including high-efficiency condensing boilers where the piping and venting allow. Boiler work rewards experience with older homes: correct sizing, near-boiler piping, and honest guidance on what the existing system can support.
Green Oaks is a wooded Lake County village of large homes on acreage, most running zoned multi-system heating and cooling. Staged multi-zone replacements and propane-to-heat-pump conversions are the typical projects.

Why Green Oaks homes need replacement planning
Green Oaks is large custom homes on wooded acreage west of the Des Plaines River, and the HVAC work follows the floor plans: two and sometimes three furnaces and condensers per house, zoned, installed at different times and now aging out on staggered schedules. Replacing one zone without looking at the others is how a homeowner ends up doing this three times in five years. Parts of the village sit off the natural-gas main and run propane, which changes both the equipment and the honest efficiency math, and makes a heat pump a genuinely competitive option here rather than a hard sell.
