Hidden Dangers in Your Home: Could CO Be Putting Your Family at Risk?

Carbon monoxide test

When winter arrives in Atlanta, most homeowners focus on staying warm. Furnaces kick on, fireplaces get more use, and homes stay sealed up tighter to keep the cold out. 

At Vital Air Services, this is also the time of year when we remind homeowners that these same winter habits can quietly increase the risk of carbon monoxide exposure if heating systems aren’t properly inspected.

Understanding the risks, recognizing early warning signs, and scheduling routine safety inspections can help protect your home and family throughout the heating season.

What Is Carbon Monoxide and Why Is It So Dangerous?

Carbon monoxide (CO) is often called the “silent danger” because it’s a colorless, odorless, and invisible gas produced when fuel-burning appliances don’t fully combust. 

Common sources inside the home include:

  • Gas furnaces
  • Fireplaces
  • Gas stoves and ovens
  • Water heaters
  • Space heaters
  • Attached garages

When these systems operate correctly and vent properly, carbon monoxide is safely carried outside. When something goes wrong, such as a cracked heat exchanger, blocked vent, or improper airflow, CO can leak into living spaces.

Because carbon monoxide has no smell or color, people are often exposed without realizing it. Prolonged or high-level exposure can lead to serious health effects and, in extreme cases, can be fatal.

Why Carbon Monoxide Risks Increase in Winter

Winter is the highest-risk season for carbon monoxide exposure, and there are several reasons why:

  • Heating systems run more often, increasing wear and stress
  • Homes are sealed tighter, trapping gases inside
  • Fireplaces and supplemental heaters are used more frequently
  • Vent pipes can become blocked by debris, nests, or ice
  • Aging equipment struggles under heavy use

Even systems that worked fine last winter can develop issues over time. That’s why routine inspections are especially important before and during the heating season.

Common Warning Signs of Carbon Monoxide Issues

While CO itself is undetectable without sensors, there are warning signs that may indicate a problem with your heating system or ventilation.

Physical Symptoms to Watch For

Carbon monoxide exposure often causes symptoms that feel like common illnesses, including:

  • Headaches
  • Dizziness
  • Fatigue
  • Nausea
  • Shortness of breath
  • Confusion or difficulty concentrating

If multiple people in the home experience similar symptoms at the same time, especially when the heat is running, it’s a red flag.

Household Clues That Something Isn’t Right

Other signs that may point to a CO issue include:

  • Carbon monoxide detector alarms sounding
  • Soot buildup around vents or appliances
  • Yellow or flickering burner flames instead of steady blue
  • Excess moisture or condensation near windows and vents
  • Pilot lights that frequently go out

These signs don’t always mean carbon monoxide is present, but they do indicate that a professional inspection is needed.

Why CO Detectors Alone Aren’t Enough

Carbon monoxide detectors are essential to have in every home, but they’re only part of the solution.

Detectors alert you after CO reaches dangerous levels. They don’t prevent leaks, diagnose equipment issues, or fix ventilation problems. Relying on detectors alone is like waiting for a smoke alarm to go off instead of maintaining your electrical system.

Preventative care focuses on stopping problems before they become emergencies.

The Importance of a Professional Carbon Monoxide Safety Check

A professional HVAC safety inspection goes beyond a basic system check. It evaluates how safely your heating equipment operates and whether carbon monoxide is being properly vented out of your home.

During a professional safety check, trained technicians will:

  • Inspect furnaces and heat exchangers for cracks or damage
  • Check flue pipes and venting systems for blockages or leaks
  • Test combustion efficiency
  • Measure carbon monoxide levels during system operation
  • Ensure appliances are drafting correctly
  • Identify early warning signs of future problems

These inspections are especially important for older systems, homes with gas appliances, or properties that haven’t had recent maintenance.

Why Preventative Maintenance Reduces CO Risk

Many carbon monoxide issues stem from systems that haven’t been serviced regularly. Over time, parts wear down, airflow becomes restricted, and small defects turn into safety concerns.

Routine preventative maintenance helps by:

  • Catching cracked heat exchangers early
  • Ensuring burners are clean and properly adjusted
  • Keeping vents and flues clear
  • Verifying safe combustion and exhaust flow

This is one of the biggest reasons winter maintenance is so critical—not just for comfort, but for safety.

Simple Steps Homeowners Can Take This Winter

In addition to professional inspections, homeowners can reduce CO risk by:

  • Installing CO detectors on every level of the home
  • Replacing detector batteries regularly
  • Keeping vents and exhaust pipes clear of debris
  • Never using outdoor heating equipment indoors
  • Scheduling annual HVAC maintenance before peak winter use

These steps work best when combined with professional system checks.
