Heating Service for Every Type of St. Louis City Home
St. Louis city homes span more than a century of heating system technology, and our technicians are trained to work on all of it from the steam boilers and hot water radiator systems that warmed the city's oldest brick homes to the high-efficiency forced-air furnaces installed in more recently renovated properties.
- Boiler and radiator systems are common in the city's oldest neighborhoods Compton Heights, Lafayette Square, Central West End, and the historic brick two-flats throughout South City. These systems circulate either steam or hot water through cast iron radiators. They're exceptionally durable; many boilers installed in the mid-20th century are still in service. When they develop problems, the symptoms are typically uneven heat, banging pipes, leaking radiator valves, or pilot light failures. We service and repair older boiler systems and advise on modern replacements when the equipment has reached end of life.
- Forced-air furnaces are the predominant system in homes that have been updated or renovated, and in neighborhoods where older systems were removed and replaced. Natural gas forced-air furnaces provide fast, efficient heat but they also require regular maintenance to stay safe. A cracked heat exchanger in a gas furnace is a serious concern, as it can allow carbon monoxide to mix with the air circulated through the home. We inspect heat exchangers during every tune-up and service call.
- Missouri winters are variable but can deliver extended cold snaps below 10°F. When the heat goes out in those conditions, it's an urgent situation. We prioritize same-day heating service calls during cold weather emergencies.
Unlike many home service companies, our technicians do not work on commission. If your furnace needs a repair, we repair it honestly without pressure toward an unnecessary replacement.

Carbon Monoxide Safety for St. Louis City Homeowners
Gas furnaces with cracked heat exchangers can produce a carbon monoxide risk. CO is colorless and odorless the only reliable protection is a working CO detector on every floor of your home. If your CO detector sounds, leave the home immediately and call 911. For furnace safety inspections, call (636) 397-3200. We recommend annual tune-ups, especially for furnaces older than 10 years or in rental properties.

Frequently Asked Questions Furnace Repair in St. Louis, MO
My St. Louis city home has a boiler with radiators can you service it?
Yes. Many St. Louis city homes particularly in Compton Heights, Lafayette Square, Soulard, and the Central West End were built with steam or hot water boiler systems that heat through cast iron radiators. We service and repair older boiler systems, including radiator valve failures, uneven heat, pilot light issues, and pressure problems. Call (636) 397-3200.
How do I know if my furnace needs repair or replacement?
If your furnace is under 15 years old and needs a single repair under $500, repair almost always makes sense. If it's over 15-18 years old, repairs are becoming more frequent, or the repair cost approaches half the cost of a new system, replacement is often the smarter long-term investment. We provide honest assessments with both options priced clearly. Call (636) 397-3200.
Is it safe to run an old furnace in a St. Louis city rental property?
Older furnaces particularly those with cracked heat exchangers can produce a carbon monoxide risk. We recommend annual safety inspections for all furnaces, and especially older units in rental or multi-family properties. If we identify a cracked heat exchanger, we'll clearly explain the safety implications and your options. Call (636) 397-3200.
