When to Replace your Furnace

Gas Furnace Installation


Most furnaces last anywhere from 15 to 25 years before you need to consider investing in a replacement. An older furnace will begin to operate less efficiently with time, and it can struggle to keep your house feeling warm. Staying proactive by replacing your older furnace is a great way to avoid these issues, and it can also provide many other benefits for homeowners. Here are the top reasons why replacing an older furnace in your home is a good idea.


1) Create a Safer Environment - One of the biggest reasons to consider a new furnace is that it's much safer than older models. An old furnace is more prone to carbon monoxide leaks and other safety concerns. Even if you don't replace your furnace, it's important to schedule annual professional maintenance to ensure it's in good working condition. Buying carbon monoxide detectors for your home is also key to detecting any problems before it's too late.


2) New Furnaces Are Much More Efficient - Modern gas furnaces are also more energy-efficient compared to furnaces manufactured even 10 years ago. Annual Fuel Utilization Efficiency (AFUE) is the standard for measuring the percentage of natural gas converted into heating power. The AFUE for older furnaces ranged anywhere from 56% to 70%, while modern furnaces are usually between 80% to 98.5%. Lighter heater exchangers, sealed combustion chambers, and variable speed fans are just a few reasons why newer furnaces are more energy efficient.


3) Reduce the Chance of Repairs - Another benefit of replacing your older furnace is that it can significantly reduce the chance of needing any repairs. On the other hand, older furnaces tend to wear down over time and are much more prone to mechanical issues. You may even begin to hear strange noises that tend to get worse over time. Constantly scheduling repairs can add up to a lot of money, which is why buying a new furnace is a cost-effective choice that saves you money and a lot of stress.


4) Save Money on Your Energy Costs - The cost of home heating can begin to rise yearly once your furnace gets to around 15 years old. An older furnace doesn't operate as efficiently due to wear and tear, resulting in a more expensive utility bill. Over time, the cost of paying a higher bill while using your furnace can quickly add up to a significant sum of money. Remaining proactive by investing in a new furnace can make a big difference in lowering your energy costs.


5) Keep Your Home Feeling Comfortable - Older furnaces may struggle to keep your house warm during the winter months. For example, you may notice that some rooms in your house are much warmer than others. An older furnace may even begin to short cycle due to damaged sensors or a malfunctioning electronic ignition system. These issues only tend to get worse over time. Purchasing a new furnace is a great way to keep your house comfortable while saving you money on your utility bill.


6) Warranty Expiration - Most warranties for a furnace will range anywhere from five to 10 years. The length of the warranty may also depend on the brand. Once the warranty period is over, you will have to pay for the repairs. A furnace that is 15 years or older most likely won't be covered under warranty, which is one more reason why investing in a new furnace is often recommended. Ultimately, a modern furnace will operate much better, and you won't have to worry about paying for costly repairs.


Replacing your older furnace is a smart decision for many homeowners. A new furnace offers various benefits, whether saving money on energy costs, keeping your home comfortable, or avoiding costly repairs. A new furnace will also be a much safer choice than an old one. The Oil Boys can inspect your furnace to help you determine if a replacement is the best option to meet your needs and budget.
