Boiler Replacement in Wilmette, Illinois
Boiler Replacement in Wilmette typically costs $7,000-$15,000 installed in 2026, depending on home size and efficiency tier.
Wilmette's older east side, near the lake, is full of century-old homes on hot-water and steam boilers - some with radiators original to the house. Boiler replacement is steady work in these neighborhoods, where the equipment is frequently a generation or more past its efficient life and the piping tells the story of decades of fixes.
| Smaller homes (under 1,500 sq ft) | $6,000-$13,200 |
| Typical homes (1,500-2,500 sq ft) | $7,000-$15,000 |
| Larger homes (2,500-4,000+ sq ft) | $7,800-$19,800 |

Boiler Replacement for Wilmette homes
The boilers we replace in Wilmette's older homes are often oversized for the radiation they serve and burdened by near-boiler piping that's been altered over the years. We assess the radiators, mains, and returns first, size the replacement to what the home actually needs, and correct the piping so the new system runs quiet and even. On steam systems in particular, sizing and piping are everything - get them wrong and the home bangs, hisses, and heats unevenly.
Where the home's chimney or venting supports it, a high-efficiency condensing boiler cuts gas use noticeably; where it doesn't, a reliable modern conventional boiler is the right call, and we'll be straight about which suits your home. Licensed, insured installers complete the changeout, rebuild the near-boiler piping to spec, and register the warranty, then walk you through any Nicor rebate the new equipment qualifies for.

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.
