March Madness: Top Reasons to Inspect Your Furnace and Ducts
March is here, and with it comes the seasonal transition from winter’s icy grip to the budding warmth of spring. While many Canadians are caught up in the excitement of March Madness, there’s another type of madness you shouldn’t overlook: the madness inside your HVAC system! At Vacu-Man Furnace and Duct Cleaning, we’re here to help you keep your HVAC system in tip-top shape — starting with knowing which warning signs actually deserve your attention first.
The March Madness Bracket: Furnace Warning Signs Ranked by Urgency
Not every furnace symptom deserves the same urgency. Some can wait for your next scheduled visit; one or two mean stop what you’re doing and call someone today. Here’s how the most common warning signs actually rank.
The “wait and schedule it” tier:
- Rising energy bills without an obvious cause
- Visible dust or dirt around vents
- A furnace older than 15 years with no other symptoms
The “book a visit soon” tier:
- Uneven heating between rooms
- Frequent short-cycling (turning on and off repeatedly)
- Musty or stale smells when the furnace runs
The “call today” tier — these mean something’s actually wrong:
- Banging, rattling, or grinding noises
- A yellow or flickering pilot light instead of steady blue — this can indicate a carbon monoxide risk. See our CO safety guide for what to do.
If you’re only going to act on one thing from this list, make it the pilot light colour — that’s the one warning sign here that’s a safety issue, not just a maintenance one.

FAQs
What if I have more than one of these warning signs at once?
Go with whichever tier is most urgent — if you have a “wait and schedule” symptom alongside a “call today” one, the call-today issue determines your timeline, not the milder one.
Is a yellow pilot light always a carbon monoxide emergency?
Not necessarily an active emergency, but it’s a real signal of incomplete combustion that needs professional attention — see our carbon monoxide guide for the full picture on what it means and what to do.
How much does furnace age actually matter if there are no other symptoms?
Age alone in the “wait and schedule” tier means it’s worth keeping an eye on and budgeting for eventual replacement — but a furnace running past 15 years with no other symptoms isn’t an emergency by itself.
