6 Problem Signs Your Furnace Is in Need of a Repair Job

If your furnace is showing problems, it can be hard to know what to do. After all, furnaces are expensive, and you don’t want to waste money on repairs if you don’t have to. But at the same time, you don’t want to ignore a problem and end up with an even bigger repair bill down the road.

So, how can you tell if your furnace needs repairs? Here are a couple of signs to watch out for:

Sign 1. Your Furnace Is Making Strange Noises

If your furnace is making strange noises, it’s definitely time for a repair. Common noises include banging, popping, and humming. These noises can indicate a variety of problems, from a loose part to a cracked heat exchanger.

Sign 2. Your Furnace Is Cycling on and off More than Usual

If your furnace is cycling on and off more frequently than normal, it could be a sign that the limit switch needs to be replaced. This switch is responsible for turning the furnace off when it gets too hot, so if it’s not working properly, your furnace could overheat and sustain damage.

Sign 3. Your Furnace Isn’t Producing Enough Heat

If your furnace isn’t producing enough heat, it could be a sign of a clogged filter, a faulty blower motor, or a problem with the gas supply. These are all relatively easy and inexpensive repairs, so it’s best to call a technician as soon as you notice the problem.

Sign 4. The Air Coming from Your Furnace Smells Strange

If the air coming from your furnace smells strange, it’s a sign that something is wrong. A burning smell could indicate a problem with the gas supply, while a musty smell could be a sign of a clogged filter. In either case, it’s best to call a technician for a diagnosis.

Sign 5. You Can See Soot around Your Furnace

If you can see soot around your furnace, it’s a sign that the burner is dirty and needs to be cleaned. This is a relatively easy repair that you can do yourself, but it’s best to call a technician if you’re not comfortable doing it.

Sign 6. Your Furnace Is over 15 Years Old

If your furnace is more than 15 years old, chances are that it is nearing the end of its lifespan. Most furnaces last anywhere between 15 to 20 years. Either way, if your furnace is around or over 15 years of age and problem signs are popping up, consider getting it repaired or replaced. If at all possible, get it replaced, as a brand-new furnace is not only more reliable but also offers new techs that can make it more efficient and effective.


So, do you notice any of the above signs with your furnace? If so, then be sure to call in experts to come and check, test, and fix your furnace! Doing so ensures the problem doesn’t get any worse, keeping things in control, repairable, and affordable. Also, do call for a repair as soon as possible. You wouldn’t want to be sitting in a house with a problematic furnace. Not only is it inefficient, but it can even pose a risk to you, your family, and your home.
