Smoke detectors are one of the simplest and most effective ways to protect your family and home. But like any device, they don't last forever—most need replacement every 8 to 10 years.
Our licensed electricians provide professional smoke detector installation, replacement, and testing across San Francisco and the Bay Area. We help you choose the right type and placement for maximum protection.
Heise's electricians can evaluate hardwired and interconnected smoke-detector systems, replace malfunctioning or aging units, and address wiring or connection issues associated with the detector system.
We service smoke and carbon monoxide detector installations and can replace appropriate units when they are no longer operating properly or when an upgrade is needed.
We remove expired or malfunctioning smoke detectors and install new, code-compliant units in the correct locations.
Hardwired smoke detectors with battery backup provide the most reliable protection and are required in many California homes.
Battery-operated detectors installed where hardwiring isn't feasible—properly placed for full-room coverage.
When one alarm sounds, they all sound. Interconnected systems ensure everyone in your home hears the alert immediately.
Dual-function alarms that detect both smoke and carbon monoxide—simplified protection in one unit.
We test every unit after installation and provide guidance on maintenance schedules to keep your system reliable.

Functional smoke and carbon monoxide detectors are vital safety components for every home. Over time, sensors degrade and internal batteries wear out, making professional evaluation and replacement necessary to keep your family protected across San Francisco and Peninsula residences.
A detector that chirps repeatedly even after installing new batteries often indicates sensor degradation, electrical terminal corrosion, or end-of-life warnings.
If pressing the test button fails to produce a loud alarm response, internal circuitry or hardwired power connections may have failed, requiring immediate unit replacement.
Smoke detectors generally lose sensing reliability after 10 years of continuous operation, while carbon monoxide sensors often require replacement after 5 to 7 years.
Older homes with standalone battery detectors benefit from upgrading to hardwired, interconnected units that trigger all alarms simultaneously when smoke is detected anywhere in the home.
Home renovations provide an ideal opportunity to review detector placement in bedrooms and hallways, ensuring compliance with current residential safety standards.
Our licensed electricians test hardwired connections, replace expired units, and install reliable combination smoke and carbon monoxide alarms in proper locations for optimal protection.
Proper smoke detector placement, wiring, and maintenance can mean the difference between a warning and a tragedy. Our licensed electricians ensure every unit is installed correctly and meets California code requirements.
