5 Clear-Cut Signs You Should Get Your Furnace Checked Out Before Winter

We recommend that all homeowners schedule furnace maintenance for their unit at least once per year, but there’s no hard-and-fast rule about when to schedule that appointment. That said, there are some clear-cut signs you should get your furnace checked out in the fall before winter. A furnace check before winter is the best way to make sure your furnace keeps your family warm all winter long.  

It’s Been Over a Year Since Your Last Furnace Check-Up

If it’s been over a year since your last furnace check-up, you should definitely schedule an appointment before winter. Furnace maintenance should be done at least once per year not only to help ensure that your unit is running properly but also to help ensure your furnace lasts as long as possible. The Government of Canada recommends a furnace cleaning and maintenance appointment once a year to make sure your furnace is as energy efficient as possible as well.

Even the slightest sounds or smells could be a sign of something more serious with your furnace, and our experts are trained to notice the warning signs of more serious problems. At your appointment, one of our technicians will check for any issues or repairs to help keep your furnace working all winter long.

Your Furnace Is Over 8 Years Old

All furnaces need regular maintenance, but it’s especially important for furnaces over 8 years old. A typical furnace lasts 8 to 15 years, with older furnaces being more likely to need repairs or replacement parts. As parts wear down, they prevent your furnace from running efficiently and depending on the part, from working entirely. A check-up from our experts will ensure that any worn parts are replaced to help prevent a breakdown when you need your furnace most. 

Depending on your furnace’s model and age, it might be time to start thinking about a replacement. At the very least, you should have it checked by a professional for the peace of mind of knowing that your older unit will make it through winter. An expert’s trained eye will be able to catch any irregularities that can cause more serious problems and complete furnace breakdowns. 

Your Furnace’s Pilot Light Is An Unusual Colour

If your furnace’s pilot light is an unusual colour, it could be a sign of bigger issues. The pilot light should be blue and any other colour could be an indication of a more serious problem. A yellow pilot light is a cause for concern as it means your furnace is not combusting properly. Improper combustion not only means your furnace isn’t working efficiently, but it also increases the risk of carbon monoxide poisoning

A regular furnace check is the best way to prevent carbon monoxide poisoning caused by your furnace. During a furnace check-up, one of our technicians will evaluate your furnace and get to the bottom of what’s causing your discoloured pilot light. Often times, a yellow pilot light is due to a clogged intake valve and it simply requires a good cleaning. Whatever the issue, we’ll make sure your furnace is running as safely and efficiently as possible. 

There Are Unusual Noises Coming from Your Furnace

According to the Heating, Refrigeration and Air Conditioning Institute of Canada, strange sounds are a sign to book a check-up with an expert. If you notice pops, squeaks, whining, or rattling noises it could be a sign that something is loose in your furnace. It could be a simple issue, for example, banging noises are often caused by a clogged air filter. Some noises can be due to more serious problems, however. A dirty burner can cause unusual noises and if left unchecked it can cause your furnace to breakdown completely. 

At the very least, a noisy furnace is a sign that your furnace isn’t running efficiently, so even if it continues to work your heating bill will be higher than it needs to be. At a furnace check-up, our technicians will get to the bottom of whatever is causing your noisy furnace. Whether it’s a loose part or something more serious, we’ll make sure your furnace is ready for winter. 

Your Furnace Isn’t Working Properly or Isn’t Working at All

Of course, if your furnace isn’t working properly, it’s time to call one of our home comfort advisors. Many people experience issues when first turning their furnace on for the winter, from their furnace blowing cold air to their furnace failing to light at all. Cold air coming from your furnace could indicate there’s a problem with the blower fan, meaning it needs to be repaired or replaced. Difficulty starting the furnace is another common problem, and it could be a simple fix due to disconnected wiring or a faulty thermostat. 

Whatever the issue, if your furnace isn’t working properly it’s best to have it checked by an expert. We’ll check your entire furnace unit to make sure it is running efficiently and reliably. Call us to book an appointment for your furnace check-up and go into winter with confidence.
