The Silent Killer Hiding in Your Home

What if we told you there’s a silent killer lurking in your home? You can’t see it or hear it, and you can’t even smell it. If your heating system is working right, it’s protecting your family from this killer, but if you have a crack in your heat exchanger, it could be leaking carbon monoxide (CO) into your home. CO is called the “invisible killer” because it’s a colorless, odorless, poisonous gas. Breathing in CO at high levels can be fatal.

There are 50,000 ER visits EACH YEAR because of carbon monoxide.

Let’s talk about the signs of carbon monoxide poisoning, plus a few ways you can keep your family safe and warm this winter!

Carbon Monoxide Poisoning

Symptoms of carbon monoxide poisoning
It’s important to be aware of the signs of carbon monoxide poisoning. If you think you might have CO poisoning, don’t push that aside! It’s better to be safe than sorry– call a professional to check out your unit.

There are six main symptoms of carbon monoxide poisoning:

  1. Headaches
  2. Dizziness
  3. Nausea
  4. Breathlessness
  5. Collapse
  6. Loss of consciousness

The Centers for Disease Control and Prevention (CDC) says at least 430 people in the U.S. die from accidental CO poisoning every year, and about 50,000 people in the U.S. visit the hospital because of CO poisoning.

Carbon Monoxide Detectors

When do your carbon monoxide detectors expire? Make sure you replace them when the time comes! Usually they last about 5 years.

Did you know carbon monoxide detectors have an expiration date? When does yours expire? You should always stay on top of replacing your CO detectors before they expire, and you should replace the batteries every year.

Do you know how often you should test your CO detectors? At least once a month! You’d be surprised how often CO detectors go bad, and sometimes you don’t know until there’s an emergency. Regularly testing your alarms makes sure they’re ready to alert you any time there might be CO in the air!

How Does CO Leak into the Home?

If you have a furnace, that also means you have a part called a heat exchanger. This allows CO produced by your furnace to safely escape your home. However, if your heat exchanger gets cracked, that allows CO to seep directly into your ductwork and it’s then distributed throughout your family’s home.

Your furnace isn’t the only thing in your home that can cause CO leaks. To make it easy to keep your family safe, we have some important “Do”s and “Don’t”s for around your house.

CO Safety NOT To-Do:

  • NEVER use charcoal grills inside.
  • NEVER heat your home by using an oven, stove top, or clothes dryer.
  • NEVER operate gas-powered tools or engines indoors even if windows are open and ventilation seems good.
  • NEVER leave your car running inside the garage. Also, when your car idles outdoors, keep one or two windows slightly open since CO can leak in from your exhaust pipe through your floorboards!
