Furnace Repair · Aurora, CO
Furnace Repair in Aurora, CO
No heat, cold air, won't start — diagnosed the same day in north Aurora. Diagnostic visit [TBD] · credited toward your repair. Written price before we touch a wrench.
One visit. Full diagnosis. Your decision.
What's included in every furnace repair visit:
- Full symptom interview — when it started, what changed, what it sounds like. Half of diagnosis is listening.
- Sequence-of-operation test — thermostat call, inducer, igniter, gas valve, flame sense, blower. We find where the chain breaks.
- Electrical & gas checks — voltage, amperage, gas pressure, and safeties (limit, rollout, pressure switch).
- Heat exchanger inspection — visual and CO check on older units. A cracked exchanger is a red-tag situation, not a repair.
- Written repair price — part, labor, and total, before anything happens. The diagnostic fee comes off the repair total.
- Old parts back — want the failed igniter in your hand as proof? It's yours. We encourage it.

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:
Runs, but blows cold air
The blower works but there's no flame. Usually an igniter, flame sensor, or gas valve issue — the three most common October failures after a summer of sitting idle. Almost always a same-visit fix.
Won't turn on at all
Check the thermostat batteries and the breaker first (we won't charge you for that). After that: control board, transformer, or a tripped safety. If the house is getting cold, call — don't wait it out.
Starts, then shuts off
Short-cycling. The furnace lights and quits — classic flame-sensor or airflow problem. A dirty filter alone can cause this, which is the cheapest fix in all of HVAC.
Making a new noise
Banging on startup, rattling, squealing, or a howl from the vents. Some sounds are harmless, some mean shut it off now. Our noise diagnosis guide sorts them out.

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
What is your service fee to come out and look at my furnace?
It's published at the top of this page — no "call for pricing" games. And if you approve the repair, the diagnostic fee comes off the total. Ask any company that won't quote their fee up front why they won't.
My furnace is blowing cold air. What could it be?
Blower running with no heat usually means the ignition sequence failed: igniter, flame sensor, or gas valve are the big three. These are the most common October failures in Aurora — furnaces sit idle all summer, then the first cold night exposes the weak part. Almost always fixed in one visit.
My furnace won't turn on at all. Is it an emergency?
Check thermostat batteries and the breaker first. If the house is holding temperature, it can wait for the next window — but in an October cold snap, indoor temps fall fast in older, draftier homes. When in doubt, call (303) 568-5036; we'll tell you honestly whether it can wait.
How long does a furnace repair take?
Most take 1–2 hours, finished the same visit from truck stock. If a part has to be ordered, we tell you that before you approve anything — and we'll talk through interim heat options so you're not freezing while it ships.
Will you try to sell me a new furnace instead of fixing it?
No. We run the same math with you that we'd run for our own house: under ~15 years old, repair wins; past that with a big-ticket failure, we show you both numbers. See the repair-vs-replace guide — and notice it starts with repair.
