The actual cost can vary based on factors like the type of detector, accessibility of the installation location, and whether any electrical work is required.
For example, a basic plug-in CO detector may be on the lower end of the range, while a hardwired unit that needs to be integrated into the home's electrical system could be on the higher end.
