Heating and Cooling in Callaway County, MO
Fulton is about 50 miles and 49 minutes from our Hermann office, so heating and cooling in Callaway County is work we book ahead, not a quick run down the road. Fulton is the county seat of a place that held 44,283 people at the 2020 census, and homes here run on a wider fuel mix than the town alone suggests.

Two things decide most jobs in this county: which side of it you live on, and what kind of house you own.
Heating and cooling in Callaway County, north to south
Callaway County covers 835 square miles of land north of the Missouri River, which forms its southern border. The north end is fairly flat with few large forests, and wind crosses it with little to stop it. The south is heavily wooded, with hills and valleys that give homes more shelter and much longer lanes. I-70, U.S. 40, U.S. 54 and U.S. 63 all cross it.
Heat loss follows the land. An exposed farmhouse in the north end works its furnace harder in January than the same house in a southern hollow, so a Manual J load calculation should reflect the site. Copying the old unit's size skips that step.

Propane, electric and manufactured homes
Callaway County's 16,485 occupied homes split this way in the 2020 to 2024 American Community Survey:
| Fuel | Share |
|---|---|
| Electricity | 53.5% |
| Bottled, tank or LP gas | 21.3% |
| Utility gas | 19.9% |
| Wood | 4.2% |
Propane outnumbers utility gas here, which surprises people who only know Fulton. Rural homes keep our propane furnace service relevant well past the city limits.
Manufactured homes are the other local feature. The survey counts 2,596 of them, or 13.9% of housing units, the highest share on our list. They come with their own rules of thumb: tight closets, ducts in the belly under the floor and equipment that has to be listed for that kind of home. Tell us up front, because a site-built furnace is usually the wrong replacement.
Fulton and the rest of the county
Fulton is the one Callaway County town with its own page. Westminster College and William Woods University give it a college-town feel, with historic homes where a ductless mini-split can beat cutting new ductwork through old walls. See that page for the city detail.
Past Fulton, the county has its own needs. Holts Summit is close to Jefferson City, and part of the capital spills over the river into Callaway County. Auxvasse, Kingdom City, Mokane and New Bloomfield are all farther from a parts counter than people think. The median home in the county dates to 1987, and 30.3% of housing has gone up since 2000, so furnace replacement decisions on systems from the 1990s and 2000s are arriving now.
Choosing the right service for a Callaway County home
| Service | Why it fits here |
|---|---|
| Propane furnace service | LP gas heats 21.3% of homes, more than utility gas, so a rural call past Auxvasse or Mokane usually starts at the tank and regulator. |
| Furnace replacement | With 30.3% of housing built since 2000, systems from those first years are reaching the point where a repair quote needs a replacement price beside it. |
| Heat pump repair | Electricity heats 53.5% of homes, and the open north end gives a heat pump a long, windy winter to work through. |
| Duct repair | The county's 2,596 manufactured homes have ducts in the belly under the floor, where a torn wrap or separated joint can go unseen for years. |
| Ductless mini splits | Fulton's historic homes and wooded southern places often have no room for new runs, so a wall unit can solve one hot room. |
| Furnace maintenance | A trip of nearly an hour makes fall tune-ups a natural booking, and long southern lanes are easier to reach before the first ice. |
Booking from Hermann: what the distance means
We are upfront about this. A trip of nearly an hour each way means we book Callaway County work ahead, and a call first keeps everyone's plans honest. Replacements and fall tune-ups fit that pattern. On a no-heat night a closer company may reach you sooner, and that is fine to ask about.
Phone (209) 563-1270 with the town, the fuel and the model number. The office keeps weekday hours, 8 to 4, and the quote comes before any work begins.
Utilities and permits in Callaway County
We could not source a reliable list of electric cooperatives or gas suppliers for this county, so we will not name any. The Callaway nuclear plant near Fulton is a generating station, and it tells you nothing about who bills your address. Your bill does.
The county courthouse is at 10 East 5th Street in Fulton, open Monday to Friday, 8 AM to 4:30 PM. Its contact page lists no planning or building office, so begin with the County Commission on the third floor and ask.

What customers say on Google
4.7 on Google(15 reviews)“During one of the coldest days in decades, and with fresh snow falling, Brian came out to our house this evening to repair our faulty furnace so we would have heat. He didn't hesitate to make the trip out. Cannot express how much we appreciate his efforts and care. I highly recommend his company for your HVAC needs. Thank you!”
“Hot water heater went out and Brian worked with us to help us find the correct replacement parts, and the repair process. He is knowledgeable, reliable and very responsive. He came out saw that we needed one more possible part and said he wouldn’t charge us labor until the water heater was up and running. We got the right parts he came out to install and had us up and running! We will definitely rely on him again for any future issues with HVAC, water heater, and or plumbing issues! It’s so nice to have hot water again!”
Good to know
Callaway County heating and cooling questions
Can a regular furnace go in a manufactured home in Callaway County?
No, not as a rule. Ask for equipment listed for manufactured housing, because air supply, venting and clearances differ from a site-built house. With about 14% of Callaway County housing in this category, mention it when you call. Have the unit's data plate and the home's year ready, so we can plan the right replacement.
Do I need to reach you before a storm if I live in Holts Summit or Auxvasse?
Yes, book before the weather turns. Neither town has its own page on this site and the drive from Hermann is a long one, so a fall tune-up beats a January call. Phone the office, tell us the town and the equipment, and we will confirm what the schedule allows.
Who regulates HVAC replacements in rural Callaway County?
We found no published county rule on mechanical permits, and the county's contact page lists no planning or building office. Start with the County Commission on the third floor of the courthouse in Fulton, and ask who handles it. Inside Fulton, ask the city. Statewide, Missouri does not license HVAC contractors as of late 2026.
