Tune-up visit · scheduled around your day
Winter doesn't negotiate. Neither do we.
What's included in every furnace tune-up:
- Full ignition-sequence test — inducer, igniter, flame sensor, gas valve. The parts that fail first after a summer idle.
- Heat exchanger inspection — visual + CO reading. Cracks here are the one finding that stops everything.
- Carbon monoxide safety check — flue draft, ambient CO, and rollout/limit safeties tested.
- Electrical testing — capacitor, contactor, blower amperage, control-board voltage. Weak parts flagged before they die in January.
- Airflow & filter — static pressure check, filter replaced or cleaned, return vents verified open.
- Thermostat calibration — anticipator settings, heat-call verification, batteries replaced.
- Burner cleaning & combustion check — burners brushed, flame pattern verified for clean, efficient burn.
- Written condition report — what's healthy, what's aging, what's next — with honest timelines, not scare tactics.

From your call to 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.
Furnace Tune-Up & Winter Prep — straight answers
What does a furnace tune-up actually include?
The full list is above — ignition sequence, heat exchanger, CO safety, electrical, airflow, thermostat, burners, and a written condition report. If anyone's "tune-up" takes 15 minutes, you bought a filter change with a fancy name.
How much does a furnace tune-up cost in Aurora?
Our price is published in the table above — one price, no "starting at." Comfort Club members get two tune-ups a year (heating + cooling) plus priority scheduling and repair discounts. See the plan.
When should I schedule it?
October, before the first sustained cold. November works; December is late; January is when you discover why October mattered.
What if my furnace breaks down after the tune-up?
That's what the 90-day no-breakdown guarantee is for: if it fails within 90 days of our tune-up, the diagnostic visit is free. In writing.
My furnace is 20+ years old. Is a tune-up worth it?
Yes — arguably more than on a new unit. The tune-up either buys you another reliable winter or gives you an honest, documented reason to plan a replacement on your schedule instead of the furnace's. Either way you win. And if replacement is the right call, here's the math.
