Smoke and CO Detector Services in Greenville, SC
Detectors are the one piece of home equipment whose entire job happens in a moment you hope never comes, and Carolina Heating Service installs and replaces smoke and carbon monoxide detectors throughout Greenville, SC. The work covers placement, wiring, and replacement schedules, the three details that determine whether a detector actually protects the household it is mounted in.
Carbon monoxide protection belongs in this conversation because CO comes from fuel-burning equipment: gas furnaces, water heaters, gas ranges, fireplaces, and attached garages. A company that services that equipment is positioned to place the detectors that monitor it.
Carolina Heating Service can help with same-day appointments available by phone and online scheduling anytime. Schedule your detector assessment today.

What Smoke and CO Detector Service Involves
A technician evaluates the home’s current coverage against placement standards, installs or replaces units, and wires interconnected systems so that when one alarm triggers, every alarm sounds. Placement follows the physics of what each device detects: smoke rises, so smoke detectors mount high; CO mixes with air, so CO detectors protect sleeping areas and the levels of the home where fuel-burning equipment runs.
Carolina Heating Service provides:
- Smoke detector installation and replacement, battery and hardwired
- Carbon monoxide detector installation, including combination smoke/CO units
- Hardwired interconnected system installation and repair, performed by licensed electricians
- Whole-home coverage assessments against current placement standards
- Detector replacement scheduling, since sensors expire even when the test button still beeps
Because CO risk starts at combustion equipment, detector work pairs naturally with heating-season safety checks; the furnace services page covers the inspection side, and gas line services cover the fuel side.
Where Detectors Belong in a Home
Smoke detectors belong inside each bedroom, outside each sleeping area, and on every level of the home including the basement. CO detectors belong outside sleeping areas and on every level with fuel-burning equipment or an attached garage. Homes relying on one hallway detector from the year the house was built are under-covered by current standards, and the gap is invisible until it matters. An assessment takes minutes and produces a specific count and placement list.

FAQs
How long do smoke and CO detectors actually last?
Smoke detectors are replaced every 10 years and CO detectors every 5 to 10 depending on the model, because the sensors degrade with age regardless of battery changes. The test button confirms the alarm circuit works; it does not confirm the sensor still detects, which is why the replacement date matters.
What is the advantage of interconnected detectors?
When one detector triggers, every detector in the home sounds. A fire that starts in the basement wakes the upstairs bedrooms immediately instead of after smoke travels, and that time difference is the entire point of early warning.
Do I need CO detectors if my home is all-electric?
Coverage still makes sense if the home has an attached garage or a fireplace, since vehicles and wood combustion both produce CO. A fully electric home with neither has minimal CO sources, and the technician will say so rather than sell unneeded units.
Why does my detector chirp even after I changed the battery?
A persistent chirp after a fresh battery usually means the unit has reached end of life or has a fault, and many models chirp specifically to signal expiration. Replacement resolves it; repeatedly swapping batteries into an expired sensor does not.
Should detectors be hardwired or battery powered?
Hardwired units with battery backup are the stronger standard because they interconnect readily and survive dead batteries, and new construction requires them. Long-life sealed battery units are the practical retrofit where wiring is impractical. The assessment lays out which mix fits your home.
