Furnace Tune-Up in Aurora, CO

"I have a furnace… I would like to be checked for the winter." That's this visit. Full winter-prep tune-up [TBD] · backed by our 90-day no-breakdown guarantee.

What's included

A real tune-up, not a filter swap

Some companies sell a "tune-up" that's 15 minutes and a new filter. Ours is 60–90 minutes of actual preventive work:

  • 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.

WINTER-PREP TUNE-UP · 80011 · OCT 2026

Furnaces that get an October tune-up fail far less often in the deep-winter months — because the weak parts get found on a Tuesday afternoon, not a Saturday night.

The October argument

Your furnace sat idle for five months. October is the test it can't afford to fail.

Here's the pattern we see every single year: a furnace runs fine all last winter, sits quiet through summer, and dies on the first real cold snap in October or November. Not because it was "about to go" — because igniters, sensors, and capacitors degrade while sitting, and the first hard cold exposes every weak point at once. A tune-up now catches those parts while the fix is cheap and scheduled. Skip it, and you meet the same parts at emergency rates in January.

Transparent pricing

One price. No "starting at" games.

What to handle before the cold settles in

The tune-up covers the furnace. Here's the rest of your October list:

  • Replace the furnace filter — monthly during heating season if you have pets or allergies.
  • Test CO detectors — every bedroom hallway, and replace any detector older than 7 years.
  • Clear the flue/exhaust — snow and ice can block high-efficiency furnace vents mid-winter; know where yours exit.
  • Reverse ceiling fans — clockwise on low pushes warm air down.
  • Check weatherstripping — older 80011 homes leak heat at doors and single-pane windows.
  • Know your shutoffs — gas valve and furnace disconnect location, before you need them at midnight.

Tune-up FAQs

Asked every October

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.
