Furnaces can last quite a while, with proper care and maintenance. They don’t last forever, however. No matter how well you take care of your furnace, there will come a point where you have to replace it. It’s important that you be able to recognize the signs that your furnace is nearing the end of its life, so that you can replace it as soon as possible. Otherwise, you might be taken by surprise when your furnace permanently breaks down on you. Read on for some of the common signs that you need to install a new furnace.
Wear and tear is the ultimate enemy for furnaces, and really any system. Over time, repeated usage will cause the parts that make up the system to wear down and become less efficient. As the efficiency of the furnace declines, it will have to stay on for a longer and longer period of time in order to achieve the same results. This will lead to a spike in your monthly heating bills. If your heating bills are going up for no apparent reason, you should look into replacing your furnace.
The same wear and tear that leads to declining efficiency will eventually cause parts of the system to start breaking down. A furnace should not need repairs more than a few times in its life, but most of the repairs it does need will come as it gets older. As parts of the furnace start to break down under the accumulation of years of wear and tear, the frequency and cost of repairs will go up. If you need to have your furnace repaired multiple times a year, you should look into getting it replaced.
