Spokane winters don't ease in gently — they arrive hard and stay late. Before October is out, you need to know your furnace is ready. Here are the five warning signs that mean trouble is coming.
Every fall, we get a wave of calls from Spokane homeowners who ignored warning signs all summer. Then October hits, the temperature drops, they flip the furnace on — and nothing. Or worse, something. A bang, a rattle, a cold room full of expensive air going nowhere.
Don't be that homeowner. Here's what to watch for before the first hard freeze.
The 5 Warning Signs
Strange Noises — Banging, Rattling, or Squealing
Your furnace should hum along quietly. If it's banging when it kicks on, that could be a delayed ignition — meaning gas is building up before igniting. That's not just annoying. It's a safety issue. A rattling blower or squealing belt means components are wearing out. Don't wait on this one.
Uneven Heat Across Your Home
One room warm, another freezing? That's a sign your furnace is struggling to distribute heat evenly — possibly due to a failing blower, blocked ducts, or a heat exchanger issue. If you're running the same temperature setting you always have and the results are inconsistent, that's a red flag.
Your Energy Bills Are Creeping Up
If your gas or electric bill spiked last winter but your usage habits didn't change, your furnace is working harder than it should. A drop in efficiency is one of the first signs a system is on its way out. A tune-up can fix it — or tell you it's time for a replacement before the winter bill hits.
The Pilot Light Is Yellow, Not Blue
A yellow or flickering pilot light is a warning sign of incomplete combustion — and potentially carbon monoxide. A healthy furnace burns a clean blue flame. If yours is yellow, orange, or flickering, call us before you run that furnace again. This is the one sign you do not ignore.
It's 15+ Years Old and Has Never Been Serviced
The average furnace lifespan is 15–20 years with proper maintenance. Without it? You're living on borrowed time. If your unit is pushing that age and has never had a professional tune-up, a Spokane winter cold snap is exactly when it will choose to give up on you. Schedule a fall inspection now — it's the cheapest insurance you'll buy all year.
"I've seen furnaces that were clearly on their last leg get pushed one more winter. Spoiler: they don't survive. Get it checked now while you have options."
What to Do Right Now
If you spotted one or more of these signs, don't wait until December. The fall is the best time to schedule a furnace inspection because:
- Appointment availability is much better than January
- Parts are in stock (not backordered from everyone's emergency calls)
- You have time to consider replacement vs. repair without freezing
- If you do need a new system, we can install before the deep freeze hits
A Bearcat tune-up takes about 90 minutes, covers 22 inspection points, and costs a fraction of an emergency repair. If we find something wrong, we'll tell you upfront — and we'll give you options, not pressure.
