Short answer
A fall tune-up cleans burners and flame sensors, checks the igniter, heat exchanger, venting and safety switches, and confirms gas pressure and airflow. It catches the small failures that otherwise strike on the first cold night, when technicians are busiest.
What a tune-up covers
Typical checks include:
- Clean flame sensor and burners
- Inspect igniter and heat exchanger
- Check venting and condensate drain
- Test safety and limit switches
- Measure temperature rise and airflow
Why fall
Problems found in October are routine appointments. The same problems in January are emergencies.
