Why Do I Need a Carbon Monoxide Detector?
Carbon monoxide (CO) is a dangerous gas that can’t be seen, smelled, or tasted, making it impossible to detect without the proper equipment. This silent threat can come from everyday household appliances like gas stoves, water heaters, furnaces, or fireplaces if they malfunction or aren’t properly ventilated. Even tiny amounts of CO exposure can lead to serious health issues, including dizziness, headaches, and confusion, and in severe cases, it could be life-threatening.
A carbon monoxide detector serves as your family’s early warning system. By identifying and alerting you to unsafe levels of CO in your home, these essential devices give you time to act before it’s too late. Without one, you may not realize there’s a problem until symptoms develop, and by then, the danger could have escalated.

I had a great experience! Ask for Evan. He came out promptly, diagnosed my heat pump quickly and came back the next day to fix it. In the process, I learned a lot about how heat pumps work. He really took the time to explain things. Would highly recommend!

Are Carbon Monoxide & Smoke Detectors Expensive?
Carbon monoxide and smoke detectors are essential safety devices that are surprisingly affordable.
Basic models often start at just a few dollars, while more advanced options with additional features are still reasonably priced. Considering the protection they provide for your family and home, these devices are a worthwhile investment.
For residents in North Carolina, there are programs that make it even easier to obtain these life-saving tools. For example, the Brunswick County Fire Marshal’s Office and the Greensboro Fire Department offer free carbon monoxide and smoke detector installation programs for eligible residents. These programs are designed to equip every home with working detectors, especially if your current devices are outdated or non-operational.
Smoke and carbon monoxide detectors play a critical role in saving lives and minimizing property damage by providing early warnings of danger. If the cost is a concern, you may be able to take advantage of these local initiatives or reach out for guidance on other resources in your area.
