Columbia HVAC Co. handles furnace repair, furnace replacement and air conditioning service throughout Centralia, MO (ZIP 65240) — the most gas-heated community in the county, where 70.2% of occupied homes run on natural gas. That is higher than any town we studied, higher even than Columbia's 53.9%. And because 62.2% of Centralia's housing predates 1980, it is a furnace town where venting, chimney and ductwork deserve as much attention as the appliance. We answer 24 hours a day with no extra fee for nights or weekends, residential and commercial, all brands.
Centralia's Housing Stock and Heating Fuel Mix
Centralia has a population of 4,541, homeownership of 71.8% and a median home value of $174,300. It sits mostly in Boone County with a small part in Audrain County, about 21 miles from Columbia, served by Centralia R-VI. The median home was built in 1971, but the town is older than that suggests: 62.2% predates 1980 and 530 units — 24.8% of the housing stock — were built before 1940.
| Heating fuel | Centralia | Columbia |
|---|---|---|
| Natural gas | 70.2% | 53.9% |
| Electricity | 27.1% | 43.4% |
| Wood | 1.7% | 0.3% |
| LP / bottled propane | 1.0% | 1.6% |
What 70% Natural Gas Means for Equipment in Centralia
When seven homes in ten burn gas, the Centralia replacement conversation is about which gas furnace, matched to which air conditioner, vented how — not about switching fuels. Three things we work through on nearly every quote here:
- Venting on a pre-1980 house. A 90%-plus condensing furnace produces cool, wet flue gas that vents through PVC out a sidewall, not up the masonry chimney. In Centralia's older housing that frequently orphans a gas water heater on a chimney sized for two appliances, which has to be corrected in the same job. We plan it before ordering.
- Return air and static pressure. The pre-1940 quarter of town typically has retrofitted ductwork and one undersized central return. A more powerful blower fighting it is noisy, inefficient and hard on the motor you just paid for.
- Right-sizing, not matching the old tag. Replacing a 1980s furnace BTU-for-BTU usually installs something substantially oversized, because the house has since gained insulation and windows. Oversized equipment short-cycles — the most common cause of "my new furnace doesn't feel as good as the old one."
Both seasons count here: about 5,024 heating degree days and 1,248 cooling degree days a year, a January low near 21°F, a July high near 88°F, 16.5 inches of snow and 41.43 inches of precipitation — a genuine dual-load climate with two emergency seasons.

Which Utility Serves Centralia — and Which Rebates Apply
Centralia is served by an electric utility other than Boone Electric Cooperative, and it is not inside Columbia city limits — so neither regional rebate program reaches it on its own:
- Columbia Water & Light rebates do not apply. They require you to "be a City of Columbia Utilities electric customer." A Centralia address does not qualify — full Columbia rebate guide.
- Boone Electric rebates do not apply either, because Centralia is not co-op territory. Those are the $750-per-ton geothermal and $300 dual-fuel rebates, both expiring 12/31/2026; that page explains how to work out which utility you are on.
- No 2026 federal tax credit exists. 25C and 25D both ended for property placed in service after December 31, 2025 under Public Law 119-21 — what changed. A quote still showing a federal credit line for a 2026 install is wrong.
Always confirm by reading the utility name on your own electric bill. Service territory here does not follow municipal lines tidily, and we will not assert a boundary rule we cannot verify. In unincorporated Boone County a building permit is required for HVAC installation or upgrade — and while the county requires that permit, state statute does not allow it to license contractors. Resource Management, (573) 886-4330. We pull the permit and handle the paperwork.
Around Centralia
Centralia was established in 1857, and its industrial anchor arrived fifty years later: the A.B. Chance Company, founded in 1907 and now Hubbell Power Systems, employs roughly 860 people in town and earned Centralia its nickname, the "Anchor Capital of the World." The town's best-known historical event is the Centralia Massacre of September 27, 1864. A steady manufacturing employer is also why Centralia has real commercial HVAC demand alongside its houses.
We also serve Hallsville, which is 63.9% natural gas, and Sturgeon, where the median home dates to 1958. If your Centralia furnace is getting expensive to keep running, start with our guide to repair versus replace.
Centralia HVAC FAQs
Why is Centralia such a gas furnace town?
Natural gas heats 70.2% of Centralia's occupied homes, the highest rate of any community we studied in the Columbia area and well above Columbia's own 53.9%. Electricity heats 27.1%, wood 1.7% and LP or propane just 1.0%.
How old is Centralia's housing?
The median Centralia home was built in 1971, 62.2% of the town's housing predates 1980, and 530 units — 24.8% of all housing in Centralia — were built before 1940.
Do I need to replace my chimney flue when I put in a high-efficiency furnace in Centralia?
You need a new vent, not necessarily a new chimney. A condensing furnace at 90% efficiency or above vents through PVC out a sidewall rather than up the masonry flue. In Centralia's older homes that often leaves a gas water heater alone on an oversized chimney, which has to be addressed as part of the same job.
Do Columbia Water and Light rebates apply in Centralia?
No. Those rebates require you to be a City of Columbia Utilities electric customer, and a Centralia address is not. Centralia is also served by an electric utility other than Boone Electric Cooperative, so the co-op's $750-per-ton geothermal and $300 dual-fuel rebates do not apply either. Check the utility name printed on your electric bill to confirm, and call us at (573) 204-6161 before you let any rebate figure into your budget.
Do you handle commercial HVAC in Centralia?
Yes. We are residential and commercial, we service all brands whether or not we installed the equipment, and we answer emergency calls 24 hours a day with no extra fee for nights or weekends. Centralia has a real employer base — Hubbell Power Systems, formerly the A.B. Chance Company, employs roughly 860 people in town — and commercial rooftop units, make-up air and split systems are part of our regular work.
