Instead, it will give you subtle signs of failure that if left unchecked will eventually lead to total furnace breakdown. So, it is very important to be vigilant to the signals your furnace is showing.

We compiled the most common and important warning signs that tell your furnace might be failing so you can have it tuned up (if it’s not too late) or replaced (if need be) so you won’t be left in the cold in an unexpected time.

Your furnace makes a sound that is maybe already familiar to you.

An old furnace coupled with an outdated duct system can result to heat not evenly distributed throughout the house making some rooms being colder or warmer than others.

If you have a newer furnace, better have your duct system checked or updated so you will have the same amount of comfort wherever you are in your home.

4. Frequent Repairs

It is normal to have some parts in your furnace replaced from time to time but when you notice that the repairs and part replacements are coming closer than usual, it is probably a sign that your furnace is slowly breaking down and needs replacement. Also, if you are spending repair that costs more than 15 percent of the price of a new furnace, you might consider replacing your furnace before it rips you off with recurring repair costs and just breaks down immediately.

5. Increasing Utility Bills

Increasing Utility Bills

You might notice a noticeable and significant increase on your electricity bill and this may be caused by your furnace’s diminishing efficiency- which means it takes longer and more energy than usual for your furnace to heat your home than when it was new.

If your furnace is less than ten years old and there’s little to no maintenance issues going on, you might not need replacement but just a thermostat update, furnace tune up or a duct clean-up.

6. Old Furnace

According to ENERGY STAR, a furnace’s average product lifespan is 18-20 years. However, without proper care and maintenance, you might be looking at just 10. On the other hand, if it is well taken care of, it can reach up to 25 years.

If your furnace is nearing the end of its service life, you might consider replacing it even without the above mentioned warning signs because it is most likely already not operating at maximum efficiency and thus result in higher utility bills.
