As the weather gets colder and winter approaches, people begin to turn on their furnaces to help keep their home warm and comfortable. But in order to keep your system working well, you need to visit CM Heating or another trusted professional to have it maintained every now and then.

But what are some warning signs that your furnace could be due for a checkup? Well, that is exactly what this guide is going to take a look at. Keep reading to learn some of the many signs that your furnace could benefit from a service visit.

It is Blowing No Air or Cool Air

If your furnace is blowing no air, it is an obvious sign that it needs to be serviced. There are many reasons why your furnace might not be blowing any air that range from an issue with the blower, to problems with the thermostat, or even a clogged air filter. It could also be due to issues with your pilot light/ignition. You can try to replace the filter and see if that helps, but if not, it is a good idea to call in a professional with experience to diagnose the issue. In a similar vein, if your furnace is blowing cold air, it could be another sign that something is wrong. It will usually have something to do with the thermostat, or an issue with your gas supply.

The Furnace is Making Strange Sounds

When your furnace is running, it is normal for it to make a bit of noise. This is especially true when it starts up. But as you run it more and more often, you will eventually get familiar with the sounds it generally makes. If your furnace begins to make new sounds that you haven’t heard before, it could be cause for concern. There are many furnace noises to look out for such as banging, buzzing, creaking, scraping, rumbling, and so many others. These can be caused by anything from loose parts to worn out components. Whether they are loud and frequent, or relatively quiet and rare, they are worthy of your attention. If you hear these sounds, it is a good idea to consider turning off your furnace and calling in a pro to make sure that you aren’t accidentally doing more damage to the system.

Your Energy Bills Have Been Skyrocketing

Another telltale sign that your furnace may need to be inspected is if your energy bills begin to skyrocket. If your furnace is slowly becoming more inefficient due to age, damage, wear and tear, or something else entirely, it will begin to cost you more and more each month. While it is often the furnace that poses the problem, it could also be your ductwork. If your ducts have gaps or leaks, they could be letting heat escape, thus making your furnace work harder to keep your home warm. If you’re able, take some time to learn how to detect leaks in your ductwork to see if that might be the issue. If you notice any of these things happening in your home, it could be a sign that your furnace needs to be serviced.
