How to Know if Your Furnace Needs Replacement

An aging furnace can cost you a lot of money and prevent you from being comfortable in your home, so it is important to know when it needs to be replaced. When a furnace is too old, it may also become unsafe. You should not wait till a crisis occurs before you consider replacing it. Knowing if your furnace needs to be replaced does not require you to be a furnace expert or be mechanically-inclined. There are common signs that will help you.

The first way to know if your furnace needs replacement is if there is a certain increase in noise. It is normal for the furnace to make a little noise during its performance. However, if you notice that the noise is getting louder, or the kinds of noises the furnace makes certainly change, it is also an indicator that it needs to be replaced. You should be cautious especially when you hear banging noises, popping, rattling, clanking or squealing noises. These could be sure signs that your furnace needs to be replaced.

The second way to know if furnace has seen its best days is if you notice your energy bills going up while the cost of energy is still the same. You will need to check and see if the cost of gas or electricity has risen. If there cost of your energy source is still the same as the previous years and the bills are going up, that is another sign that the furnace needs to be replaced.

Thirdly, you may notice that the flame of the furnace is no longer blue. If the burner flame becomes yellow or starts flickering, it is an indicator of carbon monoxide leakage. Other indicators of carbon monoxide leaking in the furnace include black soot marks on walls, excess accumulation of moisture on walls as well as windows and also excessive rust on flue pipes and vents. High levels of carbon monoxide can cause death within minutes, so you would rather replace an old furnace that has CO leakage than risk losing a life.

You may also be doing frequent repairs on the funnel. When a furnace has seen its best days, the number of breakdowns may increase and repairing them may become too costly. Instead of spending more on furnace repairs, it will be more reasonable to buy a new one that will give the comfort you need in your house without many disturbances.

Another telltale sign that your furnace needs to be replaced is if your warranty has expired. Manufacturers only guarantee the furnace as well as its parts for a limited period of time that they know the furnace is supposed to last. Once a furnace goes beyond the warranty period, it may start running less efficiently and experience more breakdowns. If you find that repairs and parts replacement are becoming costly when the warranty period is over, replacing the furnace will be a much better option.
