That familiar hum indicating your furnace’s operation is a testament to the heat exchanger diligently doing its job. Here’s how it works: it activates when the thermostat senses a temperature drop below your set heat level (Thermostat). This prompts burn gas flows into the heat exchanger chamber, after starting the ignition.
The heat exchanger’s exterior walls warm up as the combustible gas exits through the outdoor vent pipe. Simultaneously, the blower motor springs to life, drawing in cold air from every corner of your home through a return air duct. This cold air then passes over the heat exchanger.
Once the furnace receives this influx of cold air, the heat exchanger’s walls elevate the air temperature. This now-warmed air is distributes throughout your home via your air ducts system. When your home achieves the desired temperature as set on the thermostat, it signals the furnace to power down.

- Lack of Hot Air
If your furnace stops producing hot air or shuts off frequently, it might be signal of a cracked heat exchanger. Continuous operation in such a scenario could lead to carbon monoxide poisoning.
- Cracks and Corrosion in Components
As your furnace heat exchanger expands and contracts, please note that any thing could happen overtime. In addition, exterior corrosion often accompanies interior breakdown. So, if you spot cracks or corrosion, seek professional assistance promptly.
- Altered Flame Color
Gas furnaces ideally produce a blue flame. Any colour other than blue, primarily yellow or flame coming out into the burner box. This is an indication that you have a damaged heat exchanger, often caused by oxygen entering the chamber.
- Unusual Noises
While some furnace noises are normal, louder sounds like banging, popping, whistling, or scraping are not. If your furnace cabinet produces unusual sounds, it’s wise to call an expert for evaluation.
- Carbon Monoxide Leak
Carbon monoxide (CO) is a toxic, odourless gas that poses serious health risks. A cracked heat exchanger can allow CO to enter your home, endangering your family. If your CO detector activates, evacuate and call 911.
- Health Issues
A functional carbon monoxide detector is essential. Without one, carbon monoxide is undetected. Exposure can lead to symptoms like nausea, fatigue, and flu-like conditions.
- Soot Buildup
Black carbon build-up inside your furnace indicates inadequate combustion, often stemming from a broken burner or a cracked heat exchanger.
- Unpleasant Odor

- Water Pooling
Water around your furnace floor may signal a broken heat exchanger, particularly if your system doesn’t have condensation issues.
