How to Choose and Install a Carbon Monoxide Detector

2/28/2025

When it comes to the safety of your home or business, one of the most important devices you can install is a carbon monoxide (CO) detector. This life-saving device can alert you to dangerous levels of carbon monoxide, a colorless, odorless gas that can be lethal at high concentrations. Here’s a guide to help you choose and install the right carbon monoxide detector for your needs.

Why You Need a Carbon Monoxide Detector

Carbon monoxide can be produced by any appliance that burns fuel, including gas stoves, furnaces, water heaters, and fireplaces. Without proper ventilation, CO can build up and pose a serious risk to your health. Installing a CO detector ensures that you are alerted to dangerous levels of this gas, giving you the time to take action and keep your family safe.

Choosing the Right Carbon Monoxide Detector

When selecting a carbon monoxide detector, consider the following factors:

  1. Power Source: CO detectors come in battery-operated, plug-in, and hard-wired versions. Battery-operated detectors offer the flexibility of being installed anywhere, but you’ll need to replace the batteries regularly. Plug-in detectors are easy to install and require less maintenance. Hard-wired detectors are connected directly to your home’s electrical system and often come with a battery backup.
  2. Sensor Type: Look for detectors with electrochemical sensors, which are the most accurate and reliable for detecting CO levels.
  3. Digital Display: A digital display shows the current CO levels in your home, allowing you to monitor any changes.
  4. Interconnectivity: Some CO detectors can be interconnected, meaning if one detector senses CO, all the alarms in your home will go off. This is especially useful in larger homes.
  5. Additional Features: Consider features such as a voice alert that can tell you the location of the CO, a peak level memory that shows the highest level of CO detected, and end-of-life indicators that let you know when the detector needs to be replaced.

Installing a Carbon Monoxide Detector

  1. Placement: Install CO detectors on every level of your home, including the basement and near attached garages. Place them outside sleeping areas and in rooms with fuel-burning appliances. Avoid installing detectors near windows, doors, or vents where airflow can interfere with accurate readings.
  2. Height: Install the detector at eye level for easy monitoring or according to the manufacturer’s instructions. CO mixes with the air and will be present at all heights, but you want to make sure the detector is easily accessible for maintenance.
  3. Mounting: Use the provided mounting hardware to securely attach the detector to the wall or ceiling. If you’re installing a plug-in detector, ensure the outlet is easily accessible.
  4. Testing: Once installed, test the detector by pressing the test button. Regularly test your detectors, typically once a month, to ensure they are functioning properly.
  5. Maintenance: Follow the manufacturer’s maintenance guidelines, such as cleaning the detector and replacing batteries or the entire unit when necessary. Detectors generally have a lifespan of 5-7 years.
