If you want to ensure that your home's furnace is operating reliably and safely when you need it most, then there are a few things that you need to know to keep an eye out for. There are certain things that your furnace will do that you should never ignore. Keep reading to learn what three of these are, and if you ever notice them, you should get in touch with a heating professional as soon as you can.

Your Furnace Is Making More Noise Than Normal

When a furnace comes on and shuts off, it will make some level of noise. The same is true as the ductwork expands and contracts. However, as your furnace is operating, you should keep your ears open for any sounds that are unusual and out of the ordinary for its operation. If you notice any vibrating or rattling during the system's operation, then it could indicate something simple like a loose panel or something more serious like a cracked heat exchanger. When the heat exchanger has suffered damage, it can leak harmful toxins into the air.

You should also listen for scraping sounds, as these could be a sign of worn-out ball bearings within the blower. When you hear these sounds, make sure to switch your furnace off to prevent further damage. High-pitched squealing noises could be a sign that lubrication of the bearings is needed or that the blower belt is loose or is frayed.

Your Furnace's Pilot Light Is Yellow in Color

As a general rule, the pilot light on your furnace should be blue. If you notice that it is a different color like yellow, then the gas is not completely combusting. This is likely a result of insufficient airflow. There is a significant risk of carbon monoxide leaking into your home. In addition, you should look for any streaks of soot near the heating system, excess moisture around the home, and excessive amounts of rust on ducts and pipes around the heating system.

Your Furnace Is Having Thermostat Issues

When you adjust the thermostat dial and the furnace does not come on or the furnace is running irregularly regardless of where you set the thermostat dial, then there is a good chance that the thermostat is defective. You may notice that some of the rooms in the home are too cold or too hot. Some other possible causes of this could be a pilot light problem or leaks in the ducting.
