Furnace Not Working? Here’s What to Check Before You Call

Waking up to a cold house is the worst—especially in the middle of a Michigan winter.
If your furnace isn’t working, don’t panic. There are a few simple things you can check before calling for service.
🌡️ 1. Check Your Thermostat
Make sure:
- It’s set to “heat”
- The temperature is set higher than the room temp
- Batteries aren’t dead
👉 This is more common than you’d think!
🧼 2. Look at Your Air Filter
A clogged filter can cause your system to overheat and shut down.
Signs:
- Weak airflow
- System turning on and off frequently
💡 Replace your filter if it’s dirty—it can fix the issue instantly.
⚡ 3. Check the Breaker
Your furnace may have tripped the breaker.
- Locate your electrical panel
- Look for a flipped switch
- Reset it if needed
🔥 4. Pilot Light or Ignition Issue
If you have an older furnace, the pilot light may be out.
Newer systems use electronic ignition, which can also fail.
👉 If you’re unsure—this is a good time to call a pro.
🚨 When to Call for Help
If your furnace still isn’t working, it could be:
- A faulty blower motor
