Smoke and carbon monoxide (CO) detectors are some of the most important safety devices in any home — yet they’re also some of the most commonly overlooked. February is a great time for homeowners to pause and make sure these life-saving systems are properly installed, tested, and up to date.
Why Smoke Detectors Matter
Smoke detectors provide early warning in the event of a fire, giving occupants valuable time to escape. Many homes have detectors installed, but during inspections we often find:
- Missing detectors in key locations
- Units that are past their service life
- Detectors that don’t respond when tested
Smoke detectors typically have a service life of 8–10 years. If the unit is older, it may still beep when tested but fail to respond properly in a real fire.
Understanding Carbon Monoxide Risks
Carbon monoxide is a colorless, odorless gas produced by fuel-burning appliances such as gas furnaces, water heaters, fireplaces, and vehicles in attached garages. Without a working CO detector, dangerous levels can build up without warning.
CO detectors generally have a shorter lifespan — about 5–7 years — and should be installed:
- Outside sleeping areas
- On each level of the home
- Near doors leading from the house to the garage
Combination smoke/CO detectors are common, but placement still matters. One device rarely covers all required locations.
Testing Isn’t Enough
Pressing the test button only confirms the alarm works — not that the sensor is still reliable. Age, dust, and environmental conditions all reduce effectiveness over time.
A Simple Step That Makes a Big Difference
Replacing outdated or missing detectors is inexpensive compared to the protection they provide.
Call to Action:
During a HouseMaster home inspection, we check for proper placement and operation of smoke and CO detectors. If you’re unsure about the age or coverage in your home, now is the time to address it — safety starts with early warning.
