Gas Furnace Tune-Up in Aurora, CO — What a $150 Fall Service Actually Covers
A furnace that ran fine in March can fail on the first 28° night in October. Blowers dry out, igniters crack, flame sensors collect oxide, and flue screens collect summer debris. None of that announces itself until the thermostat calls for heat.
Why Aurora furnaces specifically need a fall service
Three local factors make fall maintenance matter more here than the national average:
- Altitude. Combustion behaves differently at Aurora's 5,471 feet. Gas pressure and air-fuel settings that were fine at sea level need to be verified here, not assumed.
- A long idle season. An Aurora furnace typically sits unused from May through September. Dust, dry gaskets, and spiders in the burner compartment are the rule, not the exception.
- Swings into hard cold. The Front Range goes from 75° afternoons to freezing nights in a week. Systems go from zero load to full load with no ramp.
What the $150 furnace service includes
| Step | Why it matters |
|---|---|
| Filter evaluation | A restricted filter overheats the heat exchanger and shortens system life |
| Burner and flame sensor cleaning | Oxidized sensors are the #1 cause of short-cycling and no-heat calls |
| Ignition system test | Failing igniters usually give warning signs before they quit entirely |
| Heat exchanger inspection | A cracked exchanger is a carbon monoxide concern, not just a performance one |
| Blower, belt and motor check | Noisy blowers get louder and then stop; airflow affects both comfort and safety |
| Flue, vent and intake verification | Nests and debris block vents over the off-season |
| Gas pressure and airflow verification | Altitude-correct settings, verified rather than assumed |
| Thermostat cycle test | Confirms a full run-up through heat, fan, and shutoff |
| Written findings | You know what is aging out before it fails, not after |
What a no-heat call costs by comparison
An emergency no-heat visit in the middle of a cold snap is a different animal: after-hours pricing, no schedule control, and every homeowner in the metro calling the same morning. A $150 annual service is the cheap version of the same visit — scheduled on your terms, with time to deal with what it finds.
How often should a furnace actually be serviced?
Once a year, and the ideal window is early fall, before the season starts. Nationally the recommendation is annual service; in a climate that swings this hard, skipping a year is how a $150 visit becomes a $1,400 mid-January repair. If your system ran unattended through last winter, do not skip this fall.
Do you need it if the furnace still works?
That is the honest question, and the honest answer is yes — most of what a service finds is invisible while the furnace is running. Heat exchanger cracks, partially blocked flues, and ignition components on their way out all pass a "it turned on this morning" test right up until they do not.

Cooler shutdown is also $150. Book both in one visit for $200 — you save $100.

How long does the visit take?
A standard residential gas furnace service is about 60 to 90 minutes, depending on system access and condition.
Will you tell me if the furnace needs replacing?
Yes, and we will tell you when a repair is the better call. Furnaces typically last 15 to 20 years; if yours is near the end, you leave with a repair estimate and a replacement estimate so you can decide without pressure.
Do you service high-efficiency and 80% furnaces?
Yes — condensing and standard-efficiency gas furnaces, both.
Can I combine it with a swamp cooler shutdown?
That is our most-booked fall appointment. Book both in one visit for $200.
Do you offer a senior discount?
Please ask when you call, and have ID ready at the visit. Details are on our senior discount page.
