Most Geneva homeowners replace a furnace exactly once or twice in a lifetime — which is why we walk you through it like it is the first time, every time.
From homes near the Fabyan Windmill to the neighborhoods around Third Street, we have set furnaces in Geneva closets, basements, and utility rooms of every vintage.
Sizing comes from the house — envelope, ductwork, and real heating performance — because an oversized furnace short cycles its way to an early death and an undersized one loses the fight in January.

Here is when a new furnace beats another repair:
From estimate to first heating cycle:
Before any recommendation, we size up the actual building — envelope, ductwork, venting path, and how the outgoing furnace really performed through past winters — so capacity and efficiency get chosen by evidence.
Multiple tiers with real model numbers and real prices — plus the current $175 single-unit or $350 full-system discount applied where it fits. That is non-negotiable on our Geneva jobs.
Out with the old unit, in with sheet-metal transitions cut to fit, venting and condensate run to code, gas connections leak-tested, and drop cloths under every step of it. The mechanical room ends the day cleaner than we found it. Kane County homes deserve nothing less.
Instruments close out the job: temperature rise, gas pressure, static pressure, and every safety control verified against spec. Warranty registered, thermostat and filter explained, and then we get out of your way.
Furnace sizing is a local craft: a Geneva home needs equipment that handles design temperatures near zero with reserve for the polar-vortex outliers, without being so oversized it short cycles through the shoulder seasons. well-kept historic homes near downtown, many with additions and extended ductwork, plus 1990s subdivisions west of Randall — so we size the house in front of us.
What to avoid when replacing a furnace:
Replacement money, without the fog:
Watch the quote spread trap: identical furnace models get quoted thousands apart across companies, with install quality hiding in the gap — venting done right, gas pressure set with instruments, combustion tested, airflow verified. Our quotes itemize the work, and the current $350 full-system special and $175 single-unit special come off honest numbers. That is how we price work in the 60134 area — no exceptions.

Good to know
It depends on capacity, efficiency tier, and what the venting, gas, and ductwork need — so we quote in person, in writing, at multiple price points. Current specials take $175 off a single unit or $350 off a full system, and financing is available from a 550 credit score.
If the air conditioner is also mid-teens or older, pairing is usually the play: shared labor, matched components, and the $350 full-system discount. If the AC has years left, we will be the first to say leave it alone.
Yes — removal and disposal of the old equipment is part of every install.
A standard replacement is typically completed in a day. Venting changes, duct modifications, or full-system installs can add time — you will know before we start. We would rather you ask than guess.
Yes. A cracked exchanger can allow combustion gases including carbon monoxide into the air stream, and on most aging furnaces the repair cost approaches replacement anyway. This is the one diagnosis where we will not recommend limping along. Call 630-486-0401 and we will take it from there.
Our Enhancify financing partner approves scores as low as 550, with 0% promotional options for qualified customers. You can apply online in minutes before committing to anything.
With heating seasons this long, 95%+ condensing furnaces usually earn their premium back in fuel savings — but the right answer depends on your venting situation, how long you plan to stay, and your budget. We lay out the math for your actual house.
