Your Most Important Furnace Safety Questions Answered

Q: How quickly can carbon monoxide poisoning affect my family? A: CO poisoning can cause symptoms within hours of exposure. High concentrations can be fatal within minutes. If you suspect CO in your home, evacuate immediately and call us.

Q: Can I temporarily seal a cracked heat exchanger myself? A: Never attempt DIY repairs on a cracked heat exchanger. Temporary sealing can make the problem worse and create additional safety hazards. Turn off your furnace and call for emergency service.

Q: Will my homeowner’s insurance cover CO-related furnace repairs? A: Many policies cover CO-related repairs, especially if they’re deemed emergency safety repairs. We’ll help you document everything properly for your insurance claim.

Q: How do I know if my symptoms are from carbon monoxide or just the flu? A: CO poisoning symptoms often mimic flu symptoms but without fever. If multiple family members are sick simultaneously, or symptoms improve when you leave the house, evacuate and call us immediately.

Q: What’s the difference between a CO detector alarm and other furnace problems? A: CO detector alarms are life-threatening emergencies requiring immediate evacuation. Other furnace problems such as strange noises or poor heating are urgent but not immediately life-threatening.

Insider Tips to Keep Your Family Safe This Winter

After 17 years of emergency calls, I’ve learned that most CO emergencies in winter are preventable. Here’s what I tell every Minneapolis homeowner:

Watch for these early warning signs:

• Yellow or orange flames instead of blue in your furnace
• Soot buildup around vents or the furnace unit
• Humidity or condensation on windows near the furnace
• Family members feeling dizzy or nauseous indoors
• Pets acting lethargic or sick

Monthly safety checks you can do:

• Test your CO detectors by pressing the test button (proper CO detector placement is crucial)
• Check that furnace vents outside your home aren’t blocked by snow
• Make sure nothing is stored against or near your furnace
• Listen for unusual sounds when your furnace starts up

When to call for emergency service:

• Any CO detector alarm, even if it stops quickly
• Multiple family members feeling sick at the same time
• Strong gas odors near your furnace
• Visible cracks in your heat exchanger during routine inspection

“I always tell homeowners: trust your instincts. If something feels wrong with your furnace or your family’s health, don’t wait until morning to call. CO poisoning doesn’t follow a schedule.” – Mike, Owner

Real Minneapolis Families We’ve Helped

“Mike and his team saved our family. We’d been having headaches for weeks and thought it was just stress from the holidays. When our CO detector finally went off at 2 AM, Mike was at our house in 25 minutes. The heat exchanger was cracked and leaking CO into our bedroom. I don’t want to think about what would have happened if we’d waited longer.” – Seraphina K., Uptown, January 2025

The reality of furnace emergency service in Minneapolis is that we see both the best and worst outcomes. The families who call us quickly when they notice symptoms do great. The ones who wait because they don’t want to “bother” someone in the middle of the night – those are the calls that keep me up worrying.

The good news is that modern CO detection and rapid response can prevent nearly every serious poisoning incident. The challenge is that CO is invisible, odorless, and symptoms develop gradually, so people often dismiss the warning signs.
