Why Winnetka homes plan replacements early
Winnetka's housing stock is among the oldest and most valuable on the North Shore, and much of it still runs on boilers and heating systems converted from their original coal or oil setups.

How much does a new furnace or AC cost on the North Shore?

Boilers (common in older North Shore homes) run $7,000-$15,000, and heat pumps $10,000-$22,000 before rebates. Final pricing depends on system size, efficiency, and how your home is configured. Every quote is written and itemized after an in-home estimate.
Should I repair or replace my system?
As a rule of thumb, if a system is 15+ years old, needs a repair that costs more than about a third of a new unit, or has failed more than once in a season, replacement usually saves money over time. We give an honest recommendation - if a repair makes more sense, we'll say so, and we'll do the repair.
Do you do repairs, or only replacements?
Both. We repair furnaces, air conditioners, and boilers, with a $99-$169 diagnostic that is credited toward the repair and a flat repair price you approve in writing before any work starts. Most repairs run $180-$950 depending on the equipment and the fault. Replacement is what we specialize in, but that does not mean we push it - a good system with a failed part gets the part.
Do you offer a maintenance plan or service agreement?
Yes. Plans run $199-$399 per year depending on tier and how many systems the home has, and cover two seasonal visits - heating in the fall, cooling in the spring - plus priority dispatch and a discounted repair rate for members. A one-off tune-up without a plan is $129-$199. Most manufacturer warranties require documented annual maintenance, so a plan also keeps that coverage intact.
