In Ontario, a well-functioning furnace is extremely important in ensuring your home is comfortable during the colder winter months. However, even in the best conditions, your furnace can begin to deteriorate and break down. Just as Murphy’s Law predicts, your furnace has a high likelihood of giving out on one of the coldest days of the year. This is why it is important to complete an annual inspection, before the start of winter season. This way if there are any small issues, they can be corrected before they become major issues. There comes a time where repairing your furnace is just not feasible and you will need to look into furnace replacement options. But, how do you know when your furnace needs to be replaced? We asked our technicians to share some of their expert tips to help you identify when you need to replace your furnace.

How Do You Know If You Need A New Furnace?

Increase in Heating Bills

An increase in your heating bills may suggest that there is a problem with your furnace that requires immediate attention. An increase in your energy consumption can be due to multiple factors, but if you haven’t purchased any new equipment and changed your consumption patterns, you need to take a look at your furnace. If your furnace isn’t running optimally, it will work harder to produce the same amount of heat, hence the reason for the spike in your utility bills. Schedule an inspection with an HVAC professional, so they can let you know if your furnace can be repaired or if a replacement is the better choice.

Varying Temperatures

One of the signs of a damaged or underperforming furnace is inefficiency. The furnace may no longer be able to evenly distribute heat throughout your home and that will leave your home feeling warmer and cooler in different rooms. Your furnace’s inability to properly distribute heat throughout your home may happen gradually, so it may take some time for you to notice the difference in temperatures.

Strange Noises

Your furnace will always make some noise, most notably when turning on and a little less so when running. When your furnace begins to make strange and unusual sounds such as rattling, popping or squealing, it is a sign that your furnace needs to be inspected and maintenance performed and possibly even replaced.

Years of Use

The expected lifespan of a furnace is 15-20 years, and if yours is approaching or has outlived this time frame, you may have already had several repairs completed and the need will start to increase in frequency. You may want to start looking into replacement options.

Yellow Burner Flame

Carbon monoxide emissions is another way of detecting a faulty furnace, you can easily spot this by focusing on the colour of the burner flame. A blue flame indicates that the fuel is burning cleanly while a yellow flame means that there may be a gas leakage. If you spot yellow flames from your furnace, you should have a professional inspect your system to prevent potential further damage.

A faulty furnace means that the heating system in your home will not be working efficiently and the temperature of your home may become unstable, which will be especially noticeable during the winter season. Chances are that you would never know if your furnace was underperforming without conducting an annual inspection of your heating system. Catching a potential issue early on allows you to repair the problem before it becomes a major problem forcing you to complete a full furnace replacement.
