Carbon Monoxide Detector Installation
Quick answer
CO detectors installed where code and physics agree they belong, outside sleeping areas, on every level, near attached garages. Hardwired, interconnected, or combined smoke/CO units, typically $100–$300 each.Typical installed cost: $100–$300
Carbon monoxide is invisible, odorless, and kills sleeping families, which is why placement rules differ from smoke detectors and why guessing is dangerous. Any home with gas appliances, a fireplace, or an attached garage needs CO coverage; we install it interconnected and code-correct.
About Carbon Monoxide Detector Installation
CO poisoning's cruelty is its subtlety: flu-like symptoms, drowsiness, and confusion that sets in before anyone suspects the furnace. Roughly 400 Americans die from accidental CO poisoning yearly, mostly at home, mostly at night, and disproportionately during outages when generators and alternative heat come out.
Coverage rules follow the sources: fuel-burning appliances, fireplaces, and attached garages (idling cars are a classic cause). We place detectors where sleeping people will hear them, interconnect them with the smoke system where appropriate, and use 10-year sealed units that can't be silenced by a missing battery.
Homes that need CO coverage
- Gas furnace, water heater, range, or dryer
- Any fireplace, gas or wood
- Attached garage, even with an electric car (guests idle)
- Portable generator owners: your outage plan includes CO risk
- Fuel-burning space heaters or backup heat

Outside every sleeping area, on every level including the basement, and near (not inside) an attached garage. Unlike smoke, CO mixes with air, so wall or ceiling placement both work, but proximity to bedrooms is critical.
If there's an attached garage, a fireplace, or a fuel-burning backup heater, yes. Fully electric with none of those, code may not require it, but a portable generator used in an outage is exactly when CO deaths happen.
Combined units simplify hardwired interconnection and cover both hazards at code locations. We use them at overlap points and dedicated CO units where only CO rules apply.
Single chirps usually mean low battery or end-of-life; four beeps repeating means CO detected, get out and call 911. Check the pattern printed on the unit, and replace any detector older than its rated life (5–10 years).
