5 Signs Your Furnace Needs Repair Before Calgary Winter Hits

Your furnace is your best friend when those cold snaps hit. But is it ready to keep up? Catching small problems early can save you a freezing night—and a big repair bill.

1. Weird Noises
Banging, rattling, or whistling? Your furnace is trying to tell you something.

2. Uneven Heat
Some rooms freezing while others are cozy? That’s a red flag.

3. Higher Bills
If your energy bills are climbing but your thermostat hasn’t changed, it’s time for a check-up.

4. Yellow Pilot Light
It should be blue—yellow can indicate a gas or combustion issue.

5. Frequent Cycling
If your furnace turns on and off a lot, it’s overworking or malfunctioning.

Don’t wait for a -30° emergency. Call Wells Plumbing & Heating for a pre-winter furnace tune-up.
