Why Working Smoke and CO Detectors Are Essential
A working detector gives your family the warning they need to get out safely. Without one, or with one that is not functioning properly, the margin for error disappears fast.
Smoke detectors provide early warning of a fire that might otherwise go undetected until it has spread beyond control, particularly at night when everyone is asleep. Carbon monoxide is the greater invisible threat. It is colorless, odorless, and produced by gas furnaces, boilers, water heaters, and other combustion appliances that are common in Howell homes. CO poisoning causes symptoms that feel like the flu, which means people often do not realize what is happening until they are already seriously affected. In Michigan, where homes run heating systems hard for months on end, the risk of CO buildup from a malfunctioning or poorly vented appliance is real and present every winter. A properly placed, functioning detector is the only reliable way to know when CO levels in your home are rising to a dangerous level.
Signs It's Time to Replace Your Detectors
Smoke and CO detectors do not last forever, and an expired or failing detector offers little real protection. Here is when replacement is needed.
- Detector is 10 or more years old for smoke, 5 to 7 years for CO
- Detector chirps intermittently even after a fresh battery
- Test button produces no sound or a weak alarm
- Detector has been exposed to significant dust, grease, or moisture
- Detector alarms randomly without any apparent cause
- Home has no interconnected detectors and you are updating the system
- Detectors were not replaced after a recent renovation or remodel
Smoke and CO Detector Types and Technology
Not all detectors work the same way, and understanding the differences helps you choose the right protection for your home.
Ionization smoke detectors respond quickly to fast-flaming fires and are the most common type found in older homes. Photoelectric detectors are better at sensing slow, smoldering fires, which are actually responsible for the majority of home fire deaths because they produce a lot of smoke before flames develop. Dual-sensor detectors combine both technologies in a single unit, offering the broadest detection coverage for different fire types. For carbon monoxide, electrochemical sensors are the standard in quality CO detectors and provide accurate, reliable readings at the levels that matter. Combination smoke and CO detectors simplify installation and coverage in homes that need both types of protection. Hardwired interconnected systems are the strongest setup available, linking all detectors so that when one alarm sounds, every detector in the home alarms simultaneously, giving everyone in the house the earliest possible warning no matter where the threat starts.

Frequently Asked Questions
How many smoke and CO detectors does my home need?
Current code requires smoke detectors outside each sleeping area, on every level of the home including the basement, and inside each bedroom in newer construction. CO detectors are required on each level and near sleeping areas in homes with gas appliances or attached garages. We assess your home and make sure coverage meets current requirements.
What is the difference between a hardwired and battery-operated detector?
Hardwired detectors connect to your home’s electrical system and include a battery backup so they keep working during a power outage. They can also be interconnected so all detectors alarm together. Battery-operated detectors are easier to install anywhere and are a solid option in locations where running wiring is not practical.
How do I know if my CO detector is still working correctly?
Age is the most reliable indicator. Most CO detectors have a lifespan of five to seven years, after which the sensor degrades and the unit should be replaced regardless of whether it passes a button test. The manufacturer date is usually printed on the back of the unit.
Can you install interconnected detectors in an older home?
Yes. We install hardwired interconnected systems in older homes and can also use wireless interconnected detectors in situations where running new wiring between locations is not practical. We assess your home and recommend the best approach for your specific layout.
Is carbon monoxide a real risk in Howell homes?
Yes. Homes that rely on gas furnaces, boilers, water heaters, and other combustion appliances are at risk of CO buildup if equipment malfunctions or venting is compromised. Howell winters mean those appliances run hard for months at a time, making proper CO detection especially important during heating season.
