3 Signs That You Need to Replace Your Furnace

Dependable Service Since 1926

Furnaces can last a good, long time with proper care and maintenance. Unfortunately, they cannot last forever. Sooner or later, your furnace will wear out to the point where you have to replace it. You should be able to recognize the signs that your furnace is reaching the end of its life, so that you can have it replaced as soon as possible. You don’t want to have the system die at the worst possible time, like in the middle of one of the coldest months of the year. So, keep an eye out for the following signs that you need a new furnace.

Efficiency Declines

The older a furnace gets, the more wear and tear it accumulates. This wear and tear on the various parts of the system cause it to decline in efficiency. The furnace will have to stay on for a longer and longer period of time. This will lead to higher heating bills, which is a sign that the furnace is nearing the end of its life. If your furnace is costing more and more to operate every month, you should consider replacing it.

Repairs Increase

The same wear and tear on the system that causes efficiency drops also causes various parts to start breaking down. Normally, a furnace shouldn’t need repairs more than once every couple of years. If your furnace is breaking down every few months, it’s definitely a sign that you need to replace it.


Furnaces are built to last right around 20 years. Once they get older than that, they start to have problems like those listed above, which make them more expensive to operate. Even if they don’t develop serious issues, the advance of technology will make new furnaces much cheaper to operate by comparison. If your furnace is 20+ years old, talk to a professional about getting a new one.
