Furnace Replacement · Aurora, CO
Furnace Installation & Replacement in Aurora, CO
When repair stops making sense, we size and install the right furnace for your actual home — not a rule of thumb. Full written quote [TBD] · financing available.
Replace it once. Replace it right.
What's included in every furnace installation:
- Manual-J load calculation — your new furnace is sized to your house, not to "whatever was there before." Oversized units short-cycle and die young.
- Equipment options in writing — good/better/best with efficiency ratings (AFUE), warranties, and honest payback math for each tier.
- Permits pulled, inspections passed — Aurora requires permits on furnace replacements. We pull them and meet the inspector. Non-negotiable.
- Ductwork evaluation — a new furnace on leaky 1960s ducts is a wasted investment. We test and tell you straight.
- New thermostat setup — calibrated to the new equipment, programmed with you, not left on factory defaults.
- Combustion verification — CO readings, draft, and gas pressure documented after startup. You get the numbers.
- Old equipment hauled away — and the work area left cleaner than we found it.
- Written warranties — manufacturer + our labor warranty, on paper, with what's covered and for how long.

What your system is telling you
Describe it in your own words when you call — but if you want the honest version first, here it is:
1 · How old is it?
Under 15 years: repair almost always wins. Parts are available, the exchanger is likely sound, and the unit has productive years left.
Past 15–20 years: replacement enters the conversation — efficiency, parts availability, and exchanger risk all shift.
2 · What's the repair vs. replacement ratio?
If the repair costs more than ~1/3 of replacement on a 15+ year unit, replacement usually wins on pure math. A $900 repair on a 12-year-old furnace? Fix it. A $1,800 repair on a 22-year-old furnace? That's a down payment on reliability.
3 · How's the repair history?
One repair in five years is a fluke. Three repairs in two winters is a pattern — and the pattern always gets more expensive, never less. Add up the last two years of repair bills before you decide.
4 · Is the heat exchanger sound?
A cracked heat exchanger is not a repair decision — it's a safety decision. Carbon monoxide risk means the unit gets red-tagged. At that point the choice is replace the furnace, not repair it.
The 15-year rule, in plain English
We run the same math with you that we'd run for our own house. This is the framework — your system, your call.
| Factor | Repair usually wins | Replace usually wins |
|---|---|---|
| System age | Under ~15 years | Over ~15 years with a major failure |
| Repair cost | Under half the cost of replacement | Over half — the money is better in new equipment |
| Heat exchanger | Intact, no CO readings | Cracked — a safety red-tag, not a repair |
| Breakdown pattern | First real failure in years | Third visit in two seasons |
| Efficiency | Already 90%+ AFUE | 80% AFUE dinosaur from the 90s |
What efficiency actually buys you
AFUE = how much of your gas becomes heat instead of exhaust. Illustrative comparison.
What it actually costs in Aurora

| 96%+ modulating / communicating | [TBD] | Comfort-first, larger or multi-story homes |
| Ductwork modifications (if needed) | [TBD] | Quoted separately, never buried in the equipment price |

Book → diagnose → approve → fixed
Book
Call (303) 568-5036 or request online. Describe the symptom in your own words — "it won't turn on" is a complete work order.
Diagnose
A technician inspects the system, finds the actual failed part, and explains it in plain English. You see what we see.
Approve
Written price — part, labor, total — before any work begins. You approve, decline, or ask about options. No pressure either way.
Fixed
Most repairs finish the same visit. The system is test-run, safeties verified, and the work area left clean.
Guarantees, not slogans
No-pressure promise
If you decline a recommended repair, that's the end of it. You'll never get a follow-up sales call, a "limited-time" scare tactic, or a tech who won't leave without a signature.
Written prices first
Every price we quote is written down — part, labor, total — before we touch a wrench. If the number changes mid-job, the work stops until you re-approve.
We show our work
Failed parts go in your hand, not our truck. We'll photograph what we found and walk you through it, so you're buying a diagnosis — not a story.
Straight answers before you call
How much does furnace replacement cost in Aurora?
The ranges are in the table above — 80% single-stage at the low end, 96%+ modulating at the top, ductwork quoted separately. What moves the number most: efficiency tier, house size (load calc), and ductwork condition. The in-home assessment and itemized quote are free.
Should I repair or replace my 20-year-old furnace?
At 20+, replacement is usually the right math — especially if you've had 2+ repairs in recent winters or the heat exchanger shows any concern. But "usually" isn't "always": if it's running clean and the repair is small, we'll say so. Run the 15-year rule above first, then let us verify in person.
How long does installation take?
One day for a straightforward swap. Add time for ductwork modifications, chimney liner work, or permit inspections. You'll get the real timeline in the written quote — not a guess on install day.
Do you finance furnace replacement?
Yes — $0 down, monthly payments, approved in minutes. Every quote shows the monthly figure next to the cash price, because a $9,000 sticker and a $150/month payment are two very different decisions. See the options.
Will a new furnace actually lower my bills?
Going from an aging 80% unit to a 95–96% unit cuts the heating portion of your gas bill by roughly a sixth, sometimes more in older homes where the old unit was oversized and short-cycling. We'll show you the estimated payback on each tier in the quote.
