A gas fireplace that will not light or stay lit needs model-specific diagnosis. Do not bypass a safety device, adjust a gas valve, or repeatedly attempt ignition to diagnose it.
Gas heat in Fort Collins homes
Public figures for Fort Collins as a whole. They describe local housing and heating, not your home, so the visit still starts with your own chimney.
- Homes heated mainly with utility gas
- 67.8%
- 67.8% of occupied Fort Collins homes heat primarily with utility gas, so about 32.2% run on oil, electricity, propane or something else. Wood is the primary heat in 0.4% of them. Heating fuel is not a count of fireplaces, but 67.8% on utility gas shows how much of Fort Collins already has gas at the house.

- Median year built
- 1992
- Half of Fort Collins's housing units were built in 1992 or earlier, so the median Fort Collins chimney had about 31 years behind it by the 2023 end of the estimates. Denver, also in Colorado, records 1974, 18 years older. Housing of about 1992 is more often factory-built, where a repair uses the parts the manufacturer lists for that model rather than masonry materials.

- Heating degree days a year
- 5,918
- The NOAA climate-normals station nearest Fort Collins averages 5,918 heating degree days a year. Colorado Springs, also in Colorado, records 6,292, about 6% more. Degree days measure heating demand, not freeze-thaw cycles, so 5,918 says roughly how long a Fort Collins flue is in use across a year, not how much the masonry around it moves. Book before the season rather than during it.

- Owner-occupied homes
- 52.1%
- 52.1% of occupied Fort Collins homes are owner-occupied, leaving about 47.9% rented. Aurora, also in Colorado, records 63.3% owner-occupied, 11.2 percentage points higher. The 47.9% that are rented still separate noticing a fault from authorizing the repair, so say which you are when you send the request.
