Frequently Asked Questions
How often should CO detectors be replaced? +
Most expire within 5 to 7 years. Check the label or call us if you cannot remember when yours were installed.
Where should they go? +
Near bedrooms, in hallways, and near fuel-burning appliances. We place them for maximum coverage and code compliance.
Should they be hardwired or battery? +
Hardwired with battery backup is the safest. It stays powered even during an outage and meets code in most Twin Cities cities.
Can detectors be interconnected? +
Yes. For larger homes, we can link multiple detectors so when one sounds, they all do.
Why use a licensed electrician? +
Improper install leaves you unprotected. We know placement, hardwiring, and testing so the system actually works when it matters.
