Common questions about smoke & co detector replacement
Quick answers to the 6 questions we hear most about smoke & co detector replacement.
How often should smoke detectors be replaced?expand_more
Every ten years, per the National Fire Protection Association and the manufacturer's recommendation. The sensors degrade over time and become less reliable, even if the unit still beeps when you press the test button. Check the manufacture date printed on the back of the unit.
Do I need carbon monoxide detectors in Florida?expand_more
Yes, if your home has any fuel-burning appliance — gas water heater, gas range, gas dryer, or attached garage. Florida does not mandate CO detectors as broadly as some states, but any home with combustion sources should have them. It is a life safety issue.
What is the difference between ionization and photoelectric smoke detectors?expand_more
Ionization detectors respond faster to fast-flaming fires. Photoelectric detectors respond faster to slow, smoldering fires, which are more common in residential settings. Dual-sensor units that combine both technologies provide the best overall protection.
Where should smoke detectors be placed?expand_more
Florida code requires smoke detectors inside every bedroom, outside every sleeping area, and on every level of the home. We install them on the ceiling at least four inches from the nearest wall, away from kitchens and bathrooms where false alarms are common.
Can you replace hardwired smoke detectors?expand_more
We replace hardwired detectors by swapping the unit that plugs into the existing wiring harness — this is a plug-in replacement, not a new wire connection. If your home needs new wiring for interconnected detectors, that requires a licensed electrician.
My smoke detector keeps chirping. What does that mean?expand_more
A single chirp every 30 to 60 seconds means the battery needs replacing. Chirping that continues after a new battery usually means the detector itself has reached end of life and needs full replacement. We replace the unit and verify the new one communicates with any interconnected detectors.
How does our smoke & co detector replacement process work?
Every job follows a consistent process to ensure quality results.
Existing Detector Survey
We check every detector in the home — age, type (battery vs. hardwired), placement, and condition. We note any locations where detectors are missing per Florida code requirements.
Old Detector Removal
Expired and malfunctioning units are removed. For hardwired units, the power is verified off and the wiring harness is preserved for the replacement. Battery terminals are cleaned.
New Detector Installation
New detectors are mounted in code-compliant locations. Hardwired units are plugged into the existing wiring harness. Battery-only units are mounted with screws and the battery is installed.
Testing & Interconnect Verification
Every new detector is tested individually. For interconnected systems, we trigger one unit and verify that all others sound in response. We mark the installation date on each unit and brief you on the test schedule.

Need it done today?
We prioritize urgent repairs. Call us before 10 AM for same-day availability.
How much does smoke & co detector replacement cost?
Cost depends on the number of detectors being replaced and whether they are battery-only or hardwired plug-in replacements. We recommend 10-year sealed lithium battery units to eliminate annual battery changes. Multi-unit replacement on a single visit is the most cost-effective approach.
