4 Reasons to Replace Your Old Furnace Even If It Still Works

If you own an old furnace, you may be wondering why you should replace it when it’s still working fine. The short answer is that replacing your furnace can save you money in the long run while also providing you with a more efficient, reliable system. 

Today, we’ll explain why you should consider replacing your furnace when it’s still in working condition:

1. Increased Efficiency

Old furnaces may still provide you with the heating that you need, but that doesn’t mean that they’re good at it anymore. Generally, older furnaces can be inefficient, wasting energy and driving up your utility bills. All of these combined can result in a furnace that’s expensive to run, not to mention it keeps you worried about whether or not it’ll break down any time soon.

Newer models are designed to be much more efficient, using less energy and helping you save money on your utility bills. The efficiency of new furnaces is measured using the Annual Fuel Utilization Efficiency (AFUE) rating. This rating tells you how much of the energy used by the furnace is actually converted into heat. A higher AFUE rating means the furnace is more efficient.

2. Improved Reliability

Furnaces are like any other piece of equipment. As they get older, the chances of breaking down increase. Sure, yours may not have broken down yet, but you do not want to wait until it does. More often than not, it’ll break down at the worst time possible. In addition to that, an older furnace may need frequent repairs, which can prove not only time-consuming but also burns through your money.

On the other hand, new furnaces are much more reliable, won’t need as many, if any, repairs and they also come with warranties to cover the cost of repairs in case you need them. This ensures that they will run when you need them to.

3. Reduced Carbon Emissions

Older furnaces tend to produce more carbon emissions than newer models. That’s because older furnaces aren’t only missing out on energy-efficient features that make them use less fuel to pump out heat, but as parts break down, it makes the furnace less efficient as a whole. This forces it to eat up more fuel, hence increasing carbon emissions.

Replacing your furnace with a newer, more efficient model can help reduce your home’s carbon footprint, making your home more eco-friendly. This is all thanks to the new advances in technology that allows your furnace to work better while still using much less fuel.

4. Improved Indoor Air Quality

Older furnaces can spread pollutants such as dust, dirt, and mold. While these pollutants aren’t necessarily created by the furnace itself, the years of accumulated dust, dirt, and mold can easily be spread by it. And when that happens, it can hurt your health in various ways.

Newer models, on the other hand, are designed to reduce these pollutants and improve the air quality in your home. Plus, they’re new, meaning there are little to no pollutants in the machine to begin with, ensuring clean air is circulated at all times.


Is your furnace old? If so, consider replacing it soon. In doing so, you can enjoy all the benefits above and so much more, allowing you to sit back and relax while enjoying warm, clean air throughout your home. Of course, be sure to work with a professional to remove and install your furnace to make the job quick and effective!
