Should You Replace a Furnace Before it Breaks?

We all know that feeling when something in our home breaks and we have to fork over money we don’t have to get it fixed. But what if we could avoid that scenario altogether by proactively replacing things before they break? That’s the question many homeowners face when it comes to the furnace. So, should you replace a furnace before it breaks? Let’s take a look at some of the pros and cons.

Why You Should Replace It Before it Breaks

On the one hand, replacing a furnace before it breaks can save you money in the long run. Not only will you avoid the cost of an emergency repair, but you’ll also be able to take advantage of current furnace models that are more energy-efficient than older models. This means your utility bills will be lower, which will help offset the cost of the new furnace over time. We also have financing options available to make it easier for you. Newer furnaces tend to have longer lifespans than older models, so you may not have to replace them again for many years.

Why You Shouldn’t Replace It Before It Breaks

On the other hand, replacing a furnace before it breaks can be a significant expense, especially if you have an older home with a large furnace. If your furnace is still working well and doesn’t seem to be on its last legs, you may want to wait until it breaks down completely before investing in a new one. Keep in mind that furnaces usually give some kind of warning before they break down completely, so if you’re paying attention, you’ll likely have some advance notice that it’s time for a replacement.

You could also sign up as a Protection Plan member and have the reassurance that if there’s a breakdown, you won’t be left out in the cold.

When the time is right to replace your furnace?

Most homeowners know that when fall and winter come, bad and unpredictable weather will soon follow. For that reason, it’s vital to have a safe and warm environment in your home.

One of the several ways to ensure that is to have a good furnace for your heating system. However, that furnace might be in dire need of some repairs or replacement.
So, how do you know when the time is right to replace your furnace? You know by noticing the following:

The Furnace is 15+ Years Old

The age of the furnace is one of the main signs that tell you whether or not you need to replace it. After a certain amount of years, repair costs may be more than the value of the furnace, and you’ll have to replace the furnace.

So, if the furnace in your home is more than 15 years old, it’s probably time to replace it. Even though a typical lifespan of a modern furnace is between 20 and 30 years, after 15 years, it will start to work at a lower capacity. You can try to repair it, but if your heating professional tells you that it isn’t financially advisable, then you should get a new one.

The Energy Bills and Repairs Are on the Rise

If your furnace keeps getting broken or is in constant need of repair, it’s probably time to change. If your energy bills are also on the rise, then it’s definitely time to look for a new furnace.

The amount of money you’ll continue to spend on the bills and repairs will be greater than compared to the price of a new furnace.

The Furnace Produces a Lot of Noise

Most of these noises, like a rattle, buzzing, and humming, are inevitable. This may mean that the furnace requires some repairs. However, if the sounds pop up again and won’t subside even after the fixes are made, then these mechanical issues are likely irreparable or will cost too much to repair. It’s best to cut your losses and get a replacement instead.

There Is Soot Around the Registers

The furnace register or the furnace grille (both terms are used) in the ventilation system. If these registers have soot, then that can only mean your furnace is producing too much CO2 and should be turned off and inspected immediately.

Higher amounts of CO2 will cause excessive dryness that can damage flooring, furniture, and plants, and cause dry eyes and itchy throats. Besides that, in more sensitive people, it can cause respiratory issues as well. So, if there’s any soot around these registers in your home, you definitely need to get a replacement furnace.

Other Signs That Show You Need to Replace Your Furnace

● Visible cracks or rust on the furnace or around it
● Larger than the usual amount of dirt, dust, or rust around the home
● Unevenly heated rooms

If you notice one or more of these signs, it’s very likely that you need to replace your furnace. If you’re unsure about it, you can always contact Frederick Air, and our professionals will do a thorough inspection and let you know if you need to replace your furnace.


Ultimately, the decision of whether or not to replace a furnace before it breaks comes down to a number of factors including budget, the age and condition of your current furnace, and your personal preference. If you can afford to replace your furnace before it breaks and you’re comfortable with the idea of being without heat for a brief period of time while the new one is installed, then replacing it before it breaks may be the best option for you. However, if you’re on a tight budget or your furnace isn’t very old, you may want to wait until it breaks down completely before making the investment in a new one.
