Systems common in Kildeer
Kildeer's housing stock shapes the kind of work we do. We regularly service and replace Large-home zoned forced-air, Multi-furnace setups, Original 1990s equipment, High-efficiency systems, Whole-home humidification 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 Kildeer homes plan replacements early
Kildeer is a village of large custom houses on acre lots, most of them built between the mid-1980s and the early 2000s with two or three zones each. What we see repeatedly here is equipment that was correctly sized for the house as drawn and never revisited after the finished basement, the sunroom, or the bonus room over the garage got added - so one zone runs constantly and another barely calls. A replacement that copies the old nameplate reproduces that imbalance for another twenty years. These are also homes where the original builder-grade air handler is paired with an oversized condenser, which is why the upstairs never quite cools in August no matter how long the system runs.

How much does a new furnace or AC cost on the North Shore?
Installed furnace replacements typically run $4,500-$9,000, central AC $5,000-$10,000, and a full furnace-plus-AC system $9,000-$18,000. 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.
