In extreme winter, your furnace is your best friend when you need warmth and comfort. But your furnace won’t last forever. Before it stops working completely, it’ll show signs like any other machine. The last thing you want in winter is a non-functioning furnace. To avoid this situation, you need to know about the warning signs of furnace that are indicating to change your furnace. In this article, I’ll tell you about the 4 most significant furnace replacement warning signs.


Top 4 Furnace Replacement Warning Signs

1.    Your Furnace is More than 15 Years Old

The first warning sign is the age of your furnace. The average lifespan of a furnace is around 20 to 25 years at max. If your furnace is more than 15 years old, it’s time to change your furnace.

If you maintain your furnace properly, in these 15 years, you won’t face any major problems. But when your furnace crosses the 15 years mark, it’ll start showing warning signs. Your furnace is like a machine. As it gets older, it needs more repair and maintenance.

If your furnace is shut down and it needs repair that will cost you way more than 15-30% of a new furnace price. In this situation you should buy a new furnace because your old furnace will completely breakdown soon. Another reason for changing an old furnace is that a new furnace is more energy-efficient than your older one. As technology is updating day by day, furnace technology is also changing at the same time. Engineers are making your furnace more energy-efficient. So, if you switch your furnace to a new one, it’ll save you tons of money on electric bills.

If you’re looking to save money on electric bills, you can install a programmable or smart thermostat in your furnace. It’ll help you to save money on electric bills as the smart thermostat only uses electricity when and how much needed. As a result, a programmable thermostat makes your furnace energy-efficient automatically.

2.    Electric Bills are High

When your furnace isn’t working properly, it’ll consume more electricity because internal parts of your furnace will require more electricity to operate it. A steady increase in the heating bills is a sign that your furnace will shut down soon. Again, if you notice that there’s a sudden peak in the electric bills, you should contact your HVAC professional to check all the parts of your furnace is working properly.

If you maintain your furnace properly over the years, you won’t face any major problems in your furnace. For example, your furnace air ducts won’t have leakage if you maintain it properly. Air duct leakage is one of the most common reasons why your furnace electric bill is high. But after a certain time, no matter how you maintained your furnace, electric bills will go high because every part has a limited lifespan, and after that time, it won’t work efficiently.

So, if you see that there’s a sudden peak in your electric bills, you should change your furnace because it can shut down anytime. When you shift to a new furnace, you can save a lot of money on electric bills.

3.    Frequent Repairs

When your furnace is about to shut down, it’ll require frequent repairs. Your furnace is like any other machine. When any machine parts are about to shut down, it’ll require repairs to operate it. You can estimate whether you need a new furnace or not. You can simply do it by calculating the repair cost of the last two years and compare it to a new furnace. If you see that your repair is the cost is more than a new furnace, you should change your furnace as soon as possible because your repair cost will go up every day, which isn’t economical at all.

4.    Noise

When you turn on your furnace, does it make awkward noises like popping, rattling that you never heard before? If the answer is yes, your furnace is about shutdown soon. When your furnace doesn’t work efficiently, it starts to make weird noises like this. This indicates that the internal parts of your furnace parts aren’t in good shape at all. Also, if your furnace blower is turning on and off frequently, you should buy a new furnace as it’s another warning sign.
