The chill has been fierce, hasn’t it? The last few weeks in Calgary reminded us why Alberta winters are not to be taken lightly. Furnaces were running non-stop as temperatures plummeted. Many people toughed it out with older HVAC systems—likely whispering prayers every time their furnace groaned back to life. But here’s the kicker: even though Chinook winds are about to bring some much-needed warmth, the cold will be back, and it’s time to take action before your furnace faces another marathon.
What Happens During Furnace Start-Up and Why It’s a Problem
Think of your furnace like a runner. The start-up phase is like the sprint to get moving. Every time your furnace kicks on, the components work harder to ignite, heat, and distribute air. These start-up phases put stress on:
- Heat exchangers: Rapid heating and cooling can cause metal fatigue, leading to cracks.
- Motors and fans: These endure wear and tear with every cycle.
- Ignition systems: They’re particularly vulnerable to failure after constant use.
During cold snaps, furnaces cycle more frequently, pushing these components to their limits. If you survived the last few weeks without breakdowns, consider it a win—but don’t gamble with your system’s health heading into the heart of winter.

How Chinook Winds Offer a Temporary Reprieve (But Don’t Let Your Guard Down)
Ah, Chinooks—the snow-eating winds that make Calgary winters tolerable. These warm, dry föhn winds can raise temperatures dramatically, even in the dead of winter. For the next 12 weeks, we might enjoy relatively mild weather, with highs around 10°C. While it’s tempting to bask in this brief warmth and forget about your furnace, this is the perfect window to maintain or upgrade your HVAC system.
A well-tuned furnace will thank you when those temperatures plunge again, which they inevitably will. Chinooks are nature’s reminder that even fleeting warmth doesn’t cancel winter's return.
What’s Happening Out East and Why It Matters
While Calgary enjoys the mild Chinook reprieve, parts of southern Ontario are already buried under snowfall. Lake-effect squalls have dumped over 100 cm in places like Cottage Country, leaving highways closed and power knocked out. Historically, these early-season snowstorms often hint at colder weather spreading westward later in the season.
This trend should light a fire under Calgarians. While the snow hasn’t hit us yet, we know it’s just a matter of time.
Why Now Is the Time for Furnace Maintenance
With the reprieve Chinooks offer and the inevitability of colder weeks ahead, this is your chance to ensure your furnace is up to the challenge. Here’s why you shouldn’t wait:
- Prevent costly breakdowns: A service call during a cold snap can leave you waiting in the cold while HVAC companies are overwhelmed.
- Improve efficiency: Regular maintenance reduces stress on your system, saving you money on energy bills.
- Plan for the worst: If your furnace is showing signs of age, consider upgrading now rather than risking a failure mid-winter.
A Word for Those Who “Struggled Through”
If your furnace barely got you through November’s cold snap, take this as a warning. With snowstorms hitting the east and Calgary’s Chinook window keeping us warm for now, there’s no better time to make sure your heating system is up to par.
You don’t want to face a -20°C night with a furnace that’s on its last leg. The next 12 weeks might be mild, but the deep freeze isn’t far behind.
Take the Next Step
Schedule your furnace maintenance today or explore options for a high-efficiency system that can handle the long Calgary winters. Don’t wait for your system to fail; be proactive and keep your home safe and warm.
