Most Oswego 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.
Apex Climate Control installs furnaces throughout Oswego — along the Route 34 corridor and the Fox River — working out of North Aurora, about 23 minutes from our North Aurora shop.
Install day means sheet metal that fits, venting and condensate done to code, gas connections tested, and a full commissioning: temperature rise, static pressure, and safety verification before we leave.

Install day, step by step:
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. It is the same standard we bring to every Oswego visit.
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 Oswego jobs.
Old unit out, new furnace set with properly fitted transitions, venting and condensate to code, gas leak-tested, drop cloths down the whole way.
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.
A large share of Oswego furnaces went in during the same building years, and they are aging out on the same clock. Replacing yours on a mild week in your own timeline beats replacing it during a January cold snap on the emergency schedule.
The replacement missteps that cost for decades:
What a new furnace costs in Oswego — the honest levers:
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 60543 area — no exceptions.
Real customers, real Google reviews
“The Apex Climate Control technicians are simply the BEST!”
“Great service and quality work, thanks!”
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. Either way, you will get a straight answer from us.
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. That has held true on every Oswego job we have run.
Always — removal and proper disposal of the outgoing equipment is built into every install we do.
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.
That one is not a judgment call. A cracked exchanger can push combustion gases — carbon monoxide included — into your home's air, and on older furnaces the repair costs so much that replacement wins anyway. It is the single diagnosis where we will not help you limp along.
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.
One call reaches our local team — no national call center, no runaround. Serving Oswego and all of Kendall County.
