Smoke and carbon monoxide detectors aren’t flashy upgrades—but they are the most important safety devices in your home or business. When they work properly, they save lives. When they’re outdated, missing, or incorrectly installed, they create a false sense of security (which is honestly worse than none at all).
That’s why homeowners and businesses across Orange County trust O’Hagan Electric for professional smoke detector and carbon monoxide detector installation. We install modern, code-compliant systems designed to provide reliable, early warnings—so you can sleep better knowing your property and everyone inside it is protected.
From Newport Beach and Huntington Beach to Irvine, Costa Mesa, and Anaheim, we help Orange County stay safe, compliant, and up to date.
Installing detectors isn’t just about screwing something into the ceiling and hoping for the best. Placement, wiring type, power source, and interconnection all matter—and mistakes can lead to delayed alerts or nuisance alarms.
Here’s what sets us apart:
✔ Licensed, insured electricians
We follow current California building codes and manufacturer requirements—no shortcuts.
✔ Hardwired & battery-powered installations
We install hardwired detectors with battery backup as well as standalone battery-operated units, depending on your home and code requirements.
✔ Proper placement & spacing
Bedrooms, hallways, living areas, garages—placement matters, and we get it right.
✔ Interconnected systems
When one alarm sounds, they all sound—critical for larger homes and multi-level properties.
✔ Upfront, transparent pricing
No surprises. You’ll know exactly what’s included before work begins.
Smoke detectors are required in specific locations throughout residential and commercial properties—and older units may no longer meet current standards.

Replacement of outdated or non-functioning units
Our electricians ensure correct placement in bedrooms, hallways, living areas, and each level of the home—maximizing early detection and minimizing false alarms.
