Systems common in Highwood
Highwood's housing stock shapes the kind of work we do. We regularly service and replace Steam and hot-water boilers, Small-footprint furnaces, Ductless mini-splits, Townhome and condo split systems, High-efficiency systems across this area. Each calls for a different approach - boilers and steam systems differ from forced-air furnaces, and older homes often need careful venting and duct work.
Why Highwood homes plan replacements early
Highwood is the dense exception on this stretch of the North Shore: small lots, narrow frame houses, and a housing stock that skews older and much tighter than Highland Park or Lake Forest on either side of it. Many of those homes still run steam or hot-water boilers with radiators and were never ducted, so cooling arrives as window units or mini-splits rather than central air. Where forced air does exist it is often a small furnace squeezed into a closet or a low basement, and equipment selection is driven as much by physical clearance as by load. Right-sizing matters more here than almost anywhere on the North Shore, because an oversized unit in an 1,100-square-foot house short-cycles itself to death.

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.

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.
