Furnace Repair on the North Shore
A furnace that will not light, short-cycles, blows cold, or trips its limit switch is usually a specific, findable fault - a failed igniter or flame sensor, a bad inducer or blower motor, a clogged condensate trap, a pressure switch, or a control board. We diagnose the actual failure instead of guessing, quote the repair flat and in writing, and fix it in a single visit wherever the part is on the truck. No-heat calls get priority dispatch, day or night, through a Chicago winter. Where the honest answer is that a 20-year-old furnace with a cracked heat exchanger is not worth another repair, we will say so and show you what replacement costs - but a good furnace with a bad igniter gets an igniter, not a sales pitch.
Plus a $99-$169 diagnostic, credited toward the repair. Heat exchanger and control-board failures on older units can run higher, and we will tell you before we start.
Call us when you're seeing this
- No heat, or the furnace lights then shuts off
- Short-cycling - turning on and off every few minutes
- Blower runs but the air is cold
- Burning, metallic, or gas smell when it fires
- Loud bang on ignition, or a screech from the blower
- A carbon monoxide detector has gone off (leave the house, then call)
Our process
- 1Call and book a diagnostic
Tell us what the system is doing. We schedule a diagnostic visit to your home - same day where we can, and priority dispatch for no-heat and no-cool calls.
- 2We find the actual fault
A technician tests the system rather than guessing at it, and tells you what failed and why. The diagnostic fee is credited toward the repair if you go ahead.
- 3You get the price before we touch it
You approve a flat, written repair price up front. No parts get ordered and no work starts until you say yes.
- 4Repair - and the honest number if it isn't worth it
Most repairs are done in a single visit. If the repair is a poor buy against the age of the system, we show you that math and what replacement would cost, then leave the decision with you.

When a repair stops being the right buy
The rough test we use: multiply the repair price by the age of the system. If that number clears the cost of a new one, replacement is usually the better spend - and on equipment past 15 years, out of warranty, or running phased-out R-22, it often is. We will run that math with you before you approve anything, and we are happy to do the repair if that is what you want.

Frequently asked questions
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.
Do you help with ComEd, Nicor, and federal rebates?
Yes. High-efficiency furnaces, AC, heat pumps, and boilers often qualify for Nicor Gas and ComEd rebates - heat pumps can earn tiered ComEd rebates of roughly $1,400-$2,000 depending on equipment. We size and select equipment to hit rebate thresholds and hand off the documentation you need to claim them.
My furnace died in the middle of winter - can you help fast?
Yes. We run a 24/7 emergency line for no-heat and no-cool situations. When a system can't be safely or economically revived, we can often provide temporary heat and get a replacement installed quickly.
