What to Do When Your South City Furnace Stops Working in the Middle of the Night
When your furnace stops working during a St. Louis winter night, every minute counts.

First, check your thermostat settings. Many emergency calls start with a simple fix – someone bumped the temperature setting or the batteries died. If that doesn’t work, check your circuit breaker.

Listen for clicking sounds from your furnace. A clicking but no ignition usually means a failed ignitor or a pilot light that went out.

Common Furnace Failures in St. Louis Historic Homes
South City’s housing stock presents unique challenges. Most homes built before 1940 have gravity furnaces or early forced-air systems that weren’t designed for today’s efficiency standards. The narrow crawl spaces and tight mechanical rooms make modern furnace replacement difficult. Air Purification Systems.
Heat exchanger cracks are the most dangerous failure we see in older systems. The constant expansion and contraction from St. Louis’s freeze-thaw cycles eventually creates metal fatigue. A cracked heat exchanger can release carbon monoxide while still producing heat, making it a silent killer.
Thermocouple failures plague standing pilot systems common in homes built before the 1990s. These safety devices cut gas flow if the pilot light goes out, but they wear out after 5-7 years. When they fail, your furnace won’t light at all.
Blower motor issues often start with a humming sound that escalates to complete failure. The motors work harder in older ductwork with poor airflow, leading to overheating and bearing wear. You’ll notice weak airflow or complete silence when the motor fails.
Limit switch problems cause furnaces to cycle on and off rapidly. This safety device prevents overheating, but when it fails, your furnace can’t maintain temperature. You’ll feel warm air for a few minutes, then cold air, then warm again in a frustrating cycle.

Troubleshooting Your Furnace Before You Call
Before calling for emergency service, try these steps. They might save you time and money:
- Check your thermostat batteries and settings
- Verify your circuit breaker hasn’t tripped
- Make sure your furnace switch is on (looks like a light switch near the unit)
- Check your air filter – a clogged filter can shut down your system
- Listen for error codes – many modern furnaces flash LED lights in specific patterns
If your furnace has a digital display, write down any error codes. This helps our technicians diagnose problems faster when they arrive.
Check your air vents. If you feel weak airflow but hear the blower running, you might have a simple filter issue or a more serious duct problem. Remove your filter and see if airflow improves.
Look at your furnace’s age. Most furnaces last 15-20 years. If yours is older than that and needs frequent repairs, replacement might be more cost-effective than another emergency fix.
Safety First: Carbon Monoxide and Gas Leak Prevention
Carbon monoxide is odorless and colorless. Your first warning might be flu-like symptoms – headache, dizziness, nausea. Every home with gas appliances needs working carbon monoxide detectors on every level, especially near sleeping areas.
Test your carbon monoxide detectors monthly. Replace batteries annually and the entire unit every 5-7 years. Many detectors have expiration dates printed on the back.
If your carbon monoxide detector sounds, evacuate immediately. Call 911 and do not re-enter until emergency responders say it’s safe. Do not try to find the source yourself.
Gas leaks require immediate evacuation. The rotten egg smell is added to natural gas for safety. If you smell it, leave the building, avoid using any electrical switches, and call Spire Energy from outside.
Install a programmable thermostat if you don’t have one. It can prevent many emergency calls by maintaining consistent temperatures and alerting you to problems before they become critical.
Preventing Future Emergency Calls
Annual furnace maintenance costs $150-200 but can prevent 90% of emergency breakdowns. During maintenance, technicians clean burners, check heat exchangers, test safety controls, and identify worn parts before they fail.
Change your air filter every 1-3 months depending on your home. A dirty filter restricts airflow, causing your furnace to overheat and shut down. It also reduces efficiency and increases energy bills.
Keep your furnace area clear. Don’t store chemicals, paint, or flammable materials near your furnace. These can cause fires or release fumes that damage furnace components.
Seal your ductwork if it’s in unconditioned spaces. Leaky ducts lose 20-30% of your heated air, making your furnace work harder and wear out faster. This is especially important in South City’s older homes with poorly insulated basements.
Consider a whole-house humidifier. Winter air in St. Louis is extremely dry, and your furnace can’t add moisture. Proper humidity levels (30-50%) make your home feel warmer at lower temperatures, reducing furnace runtime.

Frequently Asked Questions
How long can I wait if my furnace stops working?
Not long in winter. A home can drop below freezing within 12-24 hours when it’s below 30 degrees outside. Pipes can freeze and burst, causing thousands in water damage. Call immediately if you have no heat when it’s near or below freezing.
Is emergency service more expensive at night?
Yes, but the difference is usually a flat emergency fee rather than hourly overtime rates. The fee covers technician availability and faster response. Compare this to the cost of burst pipes or extended hotel stays – emergency service is often the cheaper option.

Can I fix my furnace myself?
