Your furnace is probably something that you don’t think about too often when it is working properly. You want to stay warm throughout the winter, and without it, you wouldn’t be able to. However, you need to keep an eye on your furnace, especially if it is getting older, you need to be aware of problems that can arise. You can be clued in to a problem when there are certain warning signs present. Air Supply Heating & Air Conditioning is here to talk about some furnace warning signs that you shouldn’t ignore.
Keep an Eye on Your Pilot Light
Many newer furnaces don’t have a pilot light that is constantly on. However, there are several older furnaces that come equipped with a pilot light that needs to remain lit so that your furnace can heat your home as needed. If this is the type of furnace you have, you need to keep an eye on the light. The light should be blue when the pilot light is lit. If it starts to turn yellow, you could have a problem with a natural gas leak. Another pilot light problem that is sometimes more obvious is a pilot light that won’t stay lit. Your furnace won’t work without it, so you will know when this happens. If it is happening frequently, call in the pros.
Loud Furnace Noises
While your furnace makes a certain amount of noise during operation, it shouldn’t suddenly start sounding different. When you start to notice that there are different or louder noises coming from your furnace, it is never a good thing. Any loud clanking, banging, or even hissing should be a cause for concern and not ignored.
Rust on Heat Exchanger
The heat exchanger is a major part of your furnace. It is also a part of your furnace that can become a danger if there are problems with it. You shouldn’t be able to see any rust on your heat exchanger. If you do, it is a sign that your furnace may need to be replaced. If there is a crack or hole that forms in the heat exchanger, it will leak dangerous carbon monoxide into your home that could lead to death if it isn’t detected. Check for any rusting on your furnace every now and then.
Short Cycling Furnace
If your furnace is turning on and then off again right away before heating your home, it is called short cycling. This problem can be caused by a number of different issues, but it is a sign that there is something wrong with your furnace. Anytime you have a furnace that is short cycling, you need to have it looked at.
