Key Takeaways
- Annual maintenance prevents 80% of common gas heating failures.
- Ignition problems and thermostat issues are the top repairable faults.
- DIY troubleshooting can resolve minor issues but always prioritize safety.
- Professional repairs ensure compliance with local codes and manufacturer warranties.
Common Gas Heating System Problems
Gas heating systems face wear and tear over time. The most frequent repairable issues include:
1. Ignition Failures
Modern systems use hot surface ignitors or intermittent pilots instead of standing pilot lights. A faulty ignitor (often due to carbon buildup) is a common culprit. Symptoms include:
- Furnace not starting
- Short cycling (turning on/off rapidly)
- Error codes like “ignition lockout”
2. Thermostat Malfunctions
Nearly 30% of “no heat” calls stem from thermostat issues. Check:
| Issue | Solution |
|---|---|
| Dead batteries | Replace AA/AAA batteries |
| Incorrect settings | Switch to “heat” mode, set above room temp |
| Location problems | Move away from drafts or heat sources |
When to DIY vs. Call a Pro
DIY repairs are suitable for:
- Resetting circuit breakers
- Replacing air filters (monthly during peak use)
- Clearing vent obstructions
Always call a licensed technician for:
- Gas leaks (smell rotten eggs? Evacuate and call 911)
- Carbon monoxide concerns (install detectors!)
- Heat exchanger cracks (visible rust or holes)
Choosing a Repair Service
Select HVAC contractors with:
- NATE certification (North American Technician Excellence)
- Positive reviews on Google My Business and BBB
- Transparent pricing (avoid “too good to be true” quotes)
