Signs That Help You to Know When Your Furnace Needs Replacing

Your furnace will keep your home warm during the cold winter months. It will be in charge of ensuring that your home will remain warm and cozy even if the temperature outside is harsh and chilly. However, you have to remember that furnaces are machines that need to be maintained. Just like any well-oiled machine, your furnace will keep its promise to keep you and your family warm during the winter. 

This being said, it is essential that you ensure that your furnace is cleaned and checked regularly to ensure that it will not break down when you need it the most. However, inevitably, your furnace will reach the end of its life someday. This blog post will help you know when you need to replace your furnace. 

Signs That Help You to Know When Your Furnace Needs Replacing

1 – Higher Than Normal Power Bills

One of the most common signs of a damaged furnace is an electric bill that is higher than normal. This means that your furnace is working twice as hard because of a damaged component. A fully functioning furnace is actually going to help keep your power bill low. If you notice that your electricity bill is higher than usual while you use your furnace, it may be high time to get it checked. 

2 – It Has Reached Its Life Expectancy

On average, a furnace may be able to last for up to 18 years with proper maintenance and care. If it has been longer than this, you may want to call a professional to come and evaluate the state of your furnace. This becomes increasingly more urgent if you have an older furnace that has not been checked in a while. 

3 – Strange Sounds Are Coming From It

Any machine that makes unusual sounds will have a malfunction going on inside it. The same goes for your furnace. If you hear banging, squeaking, rattling or any other strange noises coming from your furnace, having it checked by an HVAC professional will be the right choice. 

4 – You Are Seemingly Always Having It Repaired

If you notice that you have an unusually frequent amount of repairs done on your furnace, it may need to be replaced. After all, a working furnace should not break down right after being repaired. 

5 – No Response to the Thermostat 

Another sign that your furnace may be beyond repair is that it does not respond to the thermostat. This may mean that there may be a problem with the communication between the thermostat and the other inner workings of the furnace. If repairs do not do the trick, you may have to replace the entire furnace. 


Knowing when to replace your furnace will help you avoid experiencing issues with your furnace during the cold months when you need it the most. If you live in an older home and have a furnace that you have not had checked in quite some time, it may be a good idea to have an experienced furnace technician take a look at it. It may be time to have it repaired or replaced and it is best to do these things before the cold months roll in.
