What Are Signs That Your Furnace is Going Out?

As the temperature drops, the last thing you want is for your furnace to give out. The thought of sub-zero temperatures without a functioning furnace is enough to send shivers down anyone’s spine. But how can you tell if your furnace is on its last legs? Fortunately, there are clear signs that your furnace is going out that you can watch out for.

Signs That Your Furnace Is Going Out

Here are some of the most common signs that your furnace is going out:

Strange Noises

Your furnace should not be excessively noisy. If you hear strange noises like rattling, banging, or screeching, it could mean that there is something seriously wrong with your furnace. These loud noises are often an indication that parts of your system aren’t working correctly. The longer you wait to address these issues, the more likely it is that your furnace will eventually fail.

Reduced Heat Output

If it feels like your furnace isn’t keeping your home as warm as it used to, it could be another sign of failure. Your furnace’s primary job is to keep your home at a comfortable temperature. If it’s not working properly, it won’t be able to deliver the heat you need, and you might end up feeling the chill.

Higher Utility Bills

If you’ve noticed that your heating bill has gone up lately, your furnace could be the culprit. As your furnace starts to wear out, it becomes less efficient. This means that it will need to work harder to produce the same amount of heat, driving up your energy bills.

Frequent Repairs

If your furnace is starting to reach the end of its life, it’s going to need more repairs. These repairs will become more frequent and expensive as time goes on. Eventually, it becomes more cost-effective to replace the furnace than it is to continue repairing it.


Most furnaces have a lifespan of approximately 15 to 20 years. If your furnace is older than that, it’s probably time to start considering replacing it. Even if you haven’t noticed any of the above signs of failure, an aging furnace is likely to be less efficient and more prone to issues.

What to Do If You Think Your Furnace Is About to Fail

So, what can you do if you suspect that your furnace is on its way out? The first thing you should do is call in a professional heating contractor. Schebler Heating and Air will be able to evaluate the condition of your furnace and determine if it needs repairs or replacement.

In some cases, a repair might be all that your furnace needs. Unfortunately, in other cases, replacement may be your best option. A new furnace can be expensive, but it will save you money in the long run by reducing your energy bills and decreasing the need for frequent repairs.

If you do decide to replace your furnace, there are several options to consider. One popular choice is a high-efficiency furnace. These furnaces are designed to use less energy than traditional models, ultimately saving you money on heating costs.

Another option is a heat pump system, which uses electricity to heat and cool your home. These systems are highly efficient and eco-friendly, but they can be more expensive upfront.
