Don’t get caught in the cold! 5 signs it might be time to replace your furnace

When the cold Canadian winter sets in, your furnace becomes a vital piece of your household operations. The colder temperatures are outside, the harder your furnace has to work to keep it warm inside.  The good news is that with regular maintenance and yearly service visits you can extend the life of your furnace by up to 20 years.

However, inevitably the time will come to replace your furnace. Knowing the signs for when to say out with the old and in with the new can help make sure you don’t get caught in the cold.

Here are 5 signs it might be time to buy a new furnace for your home.

  1. Rattling and Rocking Noises

Is your furnace keeping you up at night?  That’s not a good thing.  Furnaces should work quietly to keep your house warm. Any loud rattling or rocking noises are a good indicator that something is not functioning right.

2. Flickering/Faint Yellow Pilot Light

If you have a pilot light on your unit, it is likely time to consider replacing your furnace and upgrading to a high-efficiency model. These older models waste gas and cost you more money on your utility bill.

If you do have a furnace with a pilot light, check to make sure the flame is bright blue. If your pilot light keeps going out, flickers, or turns a faint yellow, you should have someone come out to check your furnace right away. There is a chance that this is only a minor problem that can be easily fixed by tightening the burner light screw or cleaning the pilot light opening or thermocouple.  However, it could also be more serious and indicate excess carbon dioxide leaking into your home.

3. Scraping Sounds

As we mentioned earlier, any noise coming from your furnace is likely not good. If you hear a scraping sound, it could indicate that the ball bearings or the blower belt are not working correctly. A qualified professional can come out to assess the issue and help you decide if it is better to repair your unit or replace it altogether.

4. Increased Utility Bills

Do your utility bills seem to be increasing a lot lately? In addition to burning a hole in your wallet, this could signal that your furnace is not working as efficiently as it should. If you cannot attribute the higher utility costs to something else, there is a good chance your system is not working as well as it could be. The good news is that a new high-efficiency furnace can help you save you up to 50% on your utility bills!

5. Uneven Heating of Rooms

Finally, if you notice that some of the rooms in your house are a lot cooler than others, it could be another sign your furnace needs to be serviced or replaced. As units get older and start to break down, they have more difficulty pushing air evenly throughout a home. It is best to get the problem fixed soon before being left in the cold.
