Highway 19 carries us north over the river and into a county that behaves more like Hermann's back yard than a separate territory. Montgomery County covers 536 square miles between Columbia and St. Louis, and it is part of the Missouri Rhineland along its southern edge. Farther north, the land opens toward I-70 and U.S. 40.
Heating and cooling in Montgomery County, river to I-70
Think of the county in three bands. Each one calls for different work.
The river bottoms. Rhineland sits across from Hermann, about 9 minutes and 6 miles out, with flood-aware rebuilt homes. Moisture is the main opponent: damp crawl spaces, summer humidity and outdoor units that have to sit above the water line. An AC that is too large for the home will cool the air without pulling the moisture out.
The middle farm country. Between the river and the interstate, farmhouses on long drives commonly run on propane or electric. Propane furnace service and a fall furnace tune-up matter more here, since these homes are a long way from a parts counter.
The north end. Montgomery City is the county seat and largest city, about 28 minutes and 22 miles north, with older housing and in-town shops. Jonesburg, High Hill, New Florence, Wellsville and Middletown are up in this part of the county too, and small businesses there can call us for rooftop unit service.

What heats Montgomery County homes
The 2020 to 2024 American Community Survey covers 4,640 occupied homes here, and the mix is more balanced than most rural counties we list.
| Fuel | Share of homes |
|---|---|
| Electricity | 50.5% |
| Utility gas | 25.9% |
| Bottled, tank or LP gas | 13.1% |
| Wood | 8.5% |
A quarter of homes on utility gas means town furnace repair calls look different from farm calls. In town we check gas pressure, flame sensors and venting. On a farm we also ask about the tank, the regulator and how far the line runs from the house.
We could not source a list of the electric cooperatives or gas suppliers working in this county, so we will not name them here. Your bill has the answer, and it decides which utility programs you can use.
Older houses and rentals in a small county
Montgomery County's housing leans old. The median home dates to 1978, and 945 of its 5,832 units, or 16.2%, were built before 1940. Renters occupy 26.6% of homes, a higher share than in Gasconade County next door, so landlords should read this page too.
Old houses tend to carry ducts added in stages, and that is where comfort problems start. Rooms at the end of a long run stay hot in July and cold in January, and duct repair often helps more than a bigger furnace would.
Which service fits which Montgomery County address?
| Service | Why it fits here |
|---|---|
| AC repair | In the humid bottoms near Rhineland, a system that cycles off quickly leaves the house clammy, so airflow and sizing come up before refrigerant does. If it quits in a heat wave, start with emergency AC repair. |
| Heat pump repair | Electricity heats about half of the county's occupied homes, and a farmhouse a long way from a parts counter should not wait for backup strips to show on the bill. |
| Furnace repair | Utility gas reaches 25.9% of homes, largely in the towns along the north end, where flame sensors and venting are the usual suspects. |
| Propane furnace service | LP gas heats 13.1% of homes across the farm country between the river and I-70, so the regulator and line run get checked along with the furnace. |
| Furnace maintenance | Renters occupy 26.6% of homes here, and a fall check with a dated record protects both the landlord and the tenant before freeze season. |
| Rooftop unit service | Small shops in Montgomery City, Jonesburg and New Florence often rely on one packaged unit, so a failed part can close the doors. |
Permits, and asking before you pour a pad
Inside a city, start at city hall. For a rural address, start with the county offices in Montgomery City. The county's position on mechanical permits is something we could not verify, so call before work starts. As of late 2026 the state sets no license for HVAC contractors, and the Missouri HVAC Authority says most local governments expect a permit on a like-for-like swap as well.
Call (209) 563-1270 and tell us your town, your fuel and your equipment. We have been just across the river since 1998.

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!”

Montgomery County heating and cooling questions
How quickly can you get across the river to Montgomery County?
Distance is rarely the problem here. Rhineland is about 9 minutes from our office by road, and Montgomery City is about 28. We cannot promise a time, because it depends on the day's calls, so phone the office and describe the problem. Those short drives make Montgomery County some of our easiest work to schedule.
Does natural gas reach homes in Montgomery County?
Some, yes. Census estimates put utility gas at 25.9% of occupied homes, the second-highest share on our county list, with electricity at 50.5% and propane at 13.1%. Gas availability changes from one address to the next, so look at your bill or for a tank. Farms outside town commonly run on propane or electric.
My home is near the river. Where should my new outdoor unit go?
Above your known high water, if you have it. Ask the city or county about floodplain rules before any new pad goes in, and look at past water marks on your own property. Raising a condenser costs little during installation and much more after a flood. We will talk through the placement before quoting.
