Winters in St. Charles, the county seat of St. Charles County, bring freezing temperatures and the occasional run of snow and ice off the Missouri River. And when the cold settles in over the Historic Main Street district and the neighborhoods spreading out toward St. Peters and O’Fallon, a furnace that quits is not a small inconvenience. It is a long, uncomfortable night.
That is where we come in. Chesterfield Service has been a family owned and operated company since 1976, and our heating team is ready to help. Call (636) 245-3591 to reach us. We are licensed, bonded and insured under License #B00298595, and every job we do is backed by a warranty.
The reality is that the humid continental climate here is hard on heating equipment. Summers run hot and humid, then winters swing to freezing, and your furnace has to carry the whole house through the cold stretch. Homes near the river bottom and the lower-lying floodplain sections face their own moisture challenges, while higher ground away from the water tends to take the brunt of the wind. Whatever part of town you live in, from near Lindenwood University to the built-up suburbs toward the county’s western edge, we handle it.

Nothing happens without your approval. And because we are a Bryant Factory Authorized Dealer in the Circle of Champions, we install equipment built to stand up to a St. Charles winter.
Furnace Repair and Replacement
A furnace that short-cycles, blows cold air, or makes new noises is telling you something. The good news is that many problems are simple fixes when caught early. But when a system is past its life, we lay out replacement options clearly so you can decide what fits your home and budget. Financing and rebates are available to help with the cost.
Heating Maintenance
Here is the problem: most furnace failures happen on the coldest night of the year, and almost always after a season of skipped maintenance. Regular tune-ups keep your system running efficiently and catch small issues before they strand you. Our Exceptional Maintenance Club membership makes that upkeep easy, and members get priority emergency response when availability is limited.
Emergency Heating
When the heat goes out during an ice storm, waiting is not an option. Our phones are answered 24/7 for emergency calls, so you can always reach a real person. Call (636) 245-3591 and we will get you on the schedule.
A quick safety note: if you ever smell gas, leave the home and call Spire’s emergency line or 911 from outside before you call us.
More Than Just Another Service Call
We are built differently than most contractors in the greater St. Louis area. We are one company for four trades, with licensed HVAC technicians, plumbers, and electricians all in-house. So a job that crosses trades is handled with one call instead of three.
Our mission is faith-based: honor God, and serve people. And that shows up in how we treat customers. Even better, the work has been recognized with the BBB Torch Award for Ethics, a St. Louis Post-Dispatch Top Work Places 2025 honor, and a Nextdoor Neighborhood Fave award.
We serve St. Charles and the wider region, including St. Louis County, St. Charles County, and communities like St. Peters, O’Fallon, Chesterfield, Ballwin, Kirkwood, Webster Groves, and Wildwood. With Interstate 70 and the Blanchette Bridge connecting the area, we are never far from your door.
Before You Call
