The Silent Threat in Your Home: Why CO Detectors Are Just as Important as Smoke Alarms

by | Jun 1, 2025

When it comes to protecting your home and family, most people remember to check their smoke detectors—but what about carbon monoxide detectors?

Carbon monoxide (CO) is an invisible, odorless, and tasteless gas that can be deadly. It’s produced whenever fuel is burned in furnaces, stoves, fireplaces, gas ranges, or vehicles. If CO builds up in a home due to poor ventilation, malfunctioning equipment, or blocked vents, it can poison the people inside—often without warning.

What Makes Carbon Monoxide So Dangerous?

  • It’s undetectable by human senses. You can’t see, smell, or taste it.
  • It builds up quietly. One faulty appliance or a car running in an attached garage can cause CO to accumulate rapidly.
  • It can be deadly. Symptoms of CO poisoning include dizziness, confusion, nausea, headache, chest pain, and loss of consciousness—and it can be fatal within minutes in high concentrations.

How CO Detectors Help

A CO detector is your first and only line of defense against carbon monoxide poisoning. These devices sound an alarm when CO levels rise, giving you time to ventilate the home and get to safety.

Here’s what you need to know:

  • CO detectors should be installed on each level of your home, especially near sleeping areas.
  • Test them monthly, and replace the batteries at least once a year.
  • Detectors have a lifespan—usually 5 to 7 years. Check the expiration date and replace if needed.
  • Never ignore a CO alarm. If it sounds, get outside immediately and call 911 or your local fire department.

Prevention Tips

  • Have your heating systems, water heaters, and any fuel-burning appliances inspected annually.
  • Never use a gas range or oven to heat your home.
  • Ensure chimneys and vents are clear of snow, leaves, and other debris.
  • Don’t run generators or grills inside garages or near open windows.
