A lady called us to say her 10-year-old furnace was not working properly. When we came out we found that the pilot system wasn’t working correctly. If the ignition system has problems, your furnace will only work intermittently or not at all. We changed the flame sensor and the furnace worked correctly afterward.
If your furnace’s burner flame is yellow instead of blue or it makes strange noises, call a professional to come out to your home and repair your unit. A yellow flame is a dangerous sign that carbon monoxide may be seeping into your home, so don’t hesitate to get in touch with us no matter what time of the day or night it may be.
