When the winter chill settles into St. Louis, MO, your furnace becomes the most important appliance in your home. However, like any mechanical system, furnaces often give off subtle warnings before they break down completely. Catching these issues early can be the difference between a quick fix and an expensive HVAC emergency in the middle of a freeze.
Common Signs Your Furnace Needs Repair
If you notice any of the following symptoms, it’s time to call in a professional to inspect your heating system.
1. Unusual or Loud Noises
While no furnace is silent, you should be concerned if you hear banging, whistling, or screeching. Banging often indicates a delayed ignition issue, while whistling could mean a belt or fan problem.
2. A Sudden Spike in Utility Bills
If your gas or electric bills have jumped significantly without a corresponding drop in temperature, your furnace is likely losing efficiency. This often happens when components are worn out, forcing the system to run longer to reach your desired temperature.
3. Frequent Cycling
Does your furnace turn on and off every few minutes? This “short-cycling” is a major red flag. It could be caused by anything from a clogged filter to a malfunctioning thermostat or an overheating heat exchanger.
4. Yellow or Flickering Burner Flame
A healthy gas furnace should have a steady, blue flame. If the flame is yellow or flickering, it’s a sign that the gas is not burning completely, which could indicate a dangerous carbon monoxide leak.
5. Persistent Cold Spots or Weak Airflow
If some rooms are warm while others remain icy, or if you barely feel air coming from the vents, your blower motor or ductwork may be failing.
How Much Does Furnace Repair Cost in St. Louis, MO?
In the St. Louis metro area, the cost of furnace repair varies depending on the severity of the issue. On average, homeowners can expect to pay:
- Service Call/Diagnostic Fee: $75 – $150
- Minor Repairs (Ignitors, Sensors, Thermostats): $150 – $300
- Major Repairs (Blower Motors, Gas Valves): $400 – $800+

FAQs
Can I repair my furnace myself?
For safety reasons, we do not recommend DIY furnace repairs. Furnaces involve high-voltage electricity and natural gas. Attempting to fix internal components yourself can lead to gas leaks, electrical fires, or the voiding of your manufacturer’s warranty. The only “DIY” tasks homeowners should perform are changing the air filter and checking thermostat batteries.

You should always choose a licensed and insured HVAC contractor. Meyer Heating & Air provides comprehensive furnace services throughout the entire St. Louis metropolitan area and parts of Illinois.
