Why furnace age matters in Highlands Ranch
Highlands Ranch was built out largely from the 1980s onward, in phases.
Gas furnaces typically run 15 to 20 years, so a good share of the equipment here is either original or on its first replacement, and both are now at the age where faults become common. What that means in practice:
- Sizing gets carried forward. A furnace sized off the nameplate without correcting for altitude, then replaced like-for-like years later, repeats the original error.
- Builder-grade 80% AFUE units are still common in the established parts of the community. Still legal, still safe if maintained, though they can cost more to operate than a newer high-efficiency system.
None of that means you need a new furnace. It means a diagnosis here is worth more than a quote.

Diagnosis
Problems we diagnose in Highlands Ranch
| What you are experiencing | What we check |
|---|---|
| Blower runs, air is cold | Flame sensor, igniter, gas valve |
| Nothing at all | Switch, breaker, thermostat, control board |
| Starts and stops repeatedly | Filter, flue, limit switch |
| Bang on startup | Ignition timing and burner condition |
| Burning or gas smell | Gas smell: leave the house first, then call |
Check the furnace switch, the breaker and the thermostat batteries before you call. Two minutes, and you may catch a simple issue before calling.

Altitude and furnace output
A gas furnace has to have its input rate set for this elevation, not for the sea-level figure on its label. We work to the manufacturer's installation manual.
This matters more here than in older suburbs because of the equipment age above. A unit installed without a high-altitude conversion, then replaced like-for-like fifteen years later, carries the same problem forward. We check for it.

Carrier, Trane, Lennox, Goodman, Rheem, Bryant, York, Amana. We are not a dealer for any of them: the recommendation is about your furnace, not a brand quota.
Permits: Douglas County, not Arapahoe
Colorado licenses HVAC work through local jurisdictions rather than at state level, so the rules here are not the same as in Littleton, Centennial or Englewood.
A furnace replacement in Highlands Ranch needs a mechanical permit from the Douglas County Building Division, classed as "basic", so no plan review. Your contractor pulls it, and must be registered with the county to do so. A straightforward repair normally needs no permit at all.
Ask who is pulling the permit before work starts. One thing worth knowing: the Highlands Ranch Metro District is a separate body and is not where a mechanical permit comes from, which is where plenty of homeowners look first. The Building Division confirms anything on this page directly: 303-660-7497.

FAQ
Frequently asked questions
My furnace is original to the house: should I replace it?
Not automatically. Age alone is not a reason. Get it diagnosed: if the heat exchanger is sound and the failure is a $250 part, repair it. If the exchanger is cracked, replacement is the only safe answer.
Do I need a permit to replace a furnace in Highlands Ranch?
Yes, a mechanical permit from the Douglas County Building Division. It is classed as a "basic" mechanical permit, so no plan review is needed. Your contractor pulls it, not you, and they must be registered with the county to do so.
Why does my furnace run constantly on cold nights?
Sometimes a fault, sometimes altitude. A unit never set up for this elevation runs at a lower input rate than its label suggests, so it runs longer to do the same work. Worth checking before anyone sells you a larger furnace.
