November has arrived, and in Calgary, that signals one thing, the long, cold winter is almost here. The city’s unpredictable weather, from sudden freezes to extreme temperature changes thanks to a Chinook, really puts a lot of stress on our heating systems. When temperatures hit -30°C, you definitely need a furnace you can depend on.
If you find yourself holding your breath every time your furnace turns on, it might be wise to move past temporary fixes and start considering a serious upgrade. At J&B Heating, we’ve been helping Calgarians for almost ten years, and we understand what it takes to keep your home cozy and safe during the harshest winters.
When’s the Best Time to Replace Your Furnace?
Typically, a gas furnace in Canada is designed to last around 15 to 20 years. Once your unit nears that 15-year point, even with the best maintenance, you’ll start to see a drop in both efficiency and reliability. Waiting until it completely breaks down on the coldest day? That’s a risky bet, especially here in Calgary.
Here are some clear signs that it’s time to reach out to a professional:
1. Repair Costs Keep Climbing
A handy guideline is the “50% Rule”. If a repair costs half or more than a brand-new unit, like a major part replacement, then it’s usually better to go for a new furnace.
2. Rising Energy Bills
As furnaces age, their parts deteriorate, making them work harder and longer to heat your home. If you’re noticing your gas bills going up year after year without a rate hike, your furnace is becoming less efficient. Investing in a new, high-efficiency system can save you a lot on your utility bills over time, quickly compensating for the initial cost.
3. Uneven Heating in Your Home
Do some rooms feel chilly while others are warm? Or are you constantly adjusting the thermostat? An older furnace often struggles to provide even heat. This could be due to a failing blower motor or loss of efficiency.
4. Unusual Noises or a Yellow Pilot Light
Don’t disregard any strange sounds coming from your furnace. Noisy rattling, banging, or squealing often signals a mechanical issue. Plus, if your older furnace has a pilot light, it should always be a bright blue. A yellow or flickering pilot light could mean it’s producing dangerous carbon monoxide, so if you see that flame, call for service right away.
