A new furnace is a 15-to-20-year relationship. The equipment matters, but the sizing, venting, and commissioning are what decide whether a Lombard home actually gets what it paid for.
From homes near Lilacia Park to the neighborhoods around downtown Lombard and the Metra station, we have set furnaces in Lombard 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:
We measure the house, inspect ducts and venting, and look at how the old system actually performed before recommending capacity and efficiency.
Several tiers, actual model numbers, actual totals — and the $175 single-unit or $350 full-system discount already applied where it belongs. Nothing quoted from memory, nothing added later. No shortcuts on that step — not in Lombard, not anywhere.
Old unit out, new furnace set with properly fitted transitions, venting and condensate to code, gas leak-tested, drop cloths down the whole way.
Temperature rise, gas pressure, static pressure, and safety controls verified with instruments; warranty registered; thermostat and filter walkthrough before we go. That is the difference homeowners in Lombard notice.
Replacement money, without the fog:
Furnace pricing moves with capacity, efficiency (80% versus 95%+ condensing), staging (single, two-stage, modulating), and the installation realities of your house — venting route, condensate drainage for high-efficiency units, plenum transitions. Phone quotes ignore all four, which is why ours come after a visit, in writing, at more than one price point. Ask around Lombard; our quotes have a reputation for matching the invoice.
Furnace sizing is a local craft: a Lombard 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. the Lilac Village's stock runs from 1920s bungalows near downtown through postwar expansions — original ductwork, additions, and equipment closets sized for smaller machines — so we size the house in front of us.
What to avoid when replacing a furnace:
Real customers, real Google reviews
“The Apex Climate Control technicians are simply the BEST!”
“Great service and quality work, thanks!”
Good to know
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. Either way, you will get a straight answer from us.
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.
It comes from the house — square footage, insulation, windows, and duct capacity — not from matching whatever was there before. Homes get air-sealed, remodeled, and re-windowed over the years; the old label is history, not guidance.
Capacity, efficiency tier, and what the venting, gas, and ducts need all move the number — so the honest version is a written in-person quote at several price points. The current specials cut $175 off a single unit or $350 off a full system, and financing opens at a 550 credit score. A quick call sorts it out faster than wondering.
If the AC is also in the 12–15+ year range, pairing them saves duplicate labor, gets matched components, and qualifies for the $350 full-system discount. If your AC is young, we will tell you to keep it.
One call reaches our local team — no national call center, no runaround. Serving Lombard and all of DuPage County.
