The gear you hope never sounds
Smoke & CO Detector Installation in Gilbert, AZ
Smoke and carbon monoxide detectors are the only devices in your home you buy hoping they never make a sound. When they do, they buy your family the minutes that matter. That job is too important for a dead battery and a thirty-year-old sensor.
AC/DC Electric installs hardwired, interconnected smoke and CO alarms across Gilbert and the East Valley — placed where code requires them, wired so that when one sounds, they all sound. Licensed, bonded, insured, and reachable 24/7.
Watch for these
Signs your alarms are asleep on the job
- Any detector more than ten years old
- Chirping that comes back after fresh batteries
- Alarms that don't sound together when one is tested
- Housings yellowed with age
- Gas appliances or an attached garage — and no CO alarm
- Bedrooms with no detector at all
- A detector hanging by its wires in the hallway
Why interconnected beats standalone
Picture a fire starting in the garage at 2 a.m. A standalone battery alarm out there can scream all it wants — you won't hear it through two closed doors and a running AC. Interconnected alarms fix that: the garage unit trips, and the one in your bedroom goes off at the same instant. That's the whole point, and it's why modern code requires interconnection in new construction.
Many older Gilbert and Mesa homes still run standalone units. We can hardwire the interconnection, or use listed wireless-interconnect models when opening walls doesn't make sense. Either way, the alarms talk to each other.
Carbon monoxide: the alarm half of homes skip
CO is colorless and odorless, and it comes from things Arizona homes actually have: gas water heaters, gas ranges, furnaces, and cars idling in attached garages. A smoke alarm cannot detect it. If you have any fuel-burning appliance or an attached garage, you need CO coverage near the sleeping areas — full stop. The Electrical Safety Foundation at https://www.esfi.org has solid background on both hazards.
Why AC/DC Electric
Detector work looks simple, and that's exactly why it gets done wrong — wrong rooms, wrong height, dead interconnect wires, mismatched brands that won't talk to each other. Our electricians install to current code, test every unit together, and walk you through the system before we leave.
It pairs naturally with an electrical safety inspection — while we're up checking alarms, we can look over the panel, GFCIs, and wiring in the same visit. One flat price, quoted before we start.

FAQ
Straight answers
How often should smoke and CO detectors be replaced?
Smoke detectors have about a ten-year life from the manufacture date printed on the back — not from when you installed them. CO sensors often expire sooner, so check the label on each unit. If you can't find a date, the detector is old enough to replace. Batteries are a separate schedule; the unit itself has a hard expiration.
Why does my detector still chirp with a brand-new battery?
A chirp that survives a battery swap usually means the unit has hit end of life and is telling you so. Other culprits: dust in the sensor, a poorly seated battery, or on hardwired units, a wiring problem upstream. We figure out which it is — and if the fix is replacement, you'll know before we do it.
Can you interconnect alarms without opening my walls?
Usually, yes. Listed wireless-interconnect detectors link to each other by radio, so when one trips, they all sound — no new cable between rooms required. Where hardwiring is practical, we'll offer that too. We'll recommend whichever route fits your house and budget after a quick look.
Do I need a CO detector in an all-electric home?
If you have an attached garage, yes — a car running in there can push CO into the house. Same if you have a gas fireplace or ever run a generator during an outage. A home with truly zero fuel-burning sources has little CO risk, but the alarms are cheap and combination units make the question moot.
Where does code require smoke detectors?
Inside every bedroom, outside each sleeping area, and on every level of the home. Placement details matter too — distance from ceilings, corners, vents, and kitchen doorways all affect whether an alarm works or nuisance-trips. We place every unit to current code, not to wherever the old one happened to hang.
