Most homeowners don’t realize their smoke and CO detectors have expiration dates—or that older models might not provide adequate protection. These devices are essential for detecting fast-moving flames and silent threats like carbon monoxide long before they become deadly. At R.S. Andrews, we offer expert installation and maintenance of detectors throughout the Atlanta Metro Area, using smart placement and updated technology to improve early warning times. Our electricians take the guesswork out of safety by ensuring every alarm is positioned correctly, wired securely, and tested thoroughly. We help protect what matters most with proactive solutions built around your home’s layout and your family’s needs.

Is It Time to Replace Your Smoke or CO Detectors?

Detectors aren’t designed to last forever—and outdated models can delay alerts or fail entirely when you need them most. Regular testing is important, but replacement is just as critical. If you notice any of the signs below, it’s time to schedule an inspection with a licensed electrician in the Greater Atlanta Area:

  • Units are over 10 years old: Most detectors lose sensitivity over time and should be replaced every decade.

  • Constant chirping or false alarms: Beeping that doesn’t stop—even after a battery change—often signals a failing unit.

  • Yellowing or discoloration of the casing: This can indicate heat exposure and plastic degradation, both of which affect function.

  • No hardwired connection or battery backup: Modern homes need layered protection with dependable power sources.

  • You don’t have detectors in every bedroom and hallway: Missing or poorly placed units reduce response time in an emergency.

  • Carbon monoxide detector hasn’t been tested in years: CO is odorless and deadly—every level of your home needs protection.

Schedule today! We’re ready to deliver expert service and a smile to your door.

Our Smoke & CO Detector Services

Smoke Detector Installation & Replacement

We install modern smoke detectors that meet current safety standards and are designed for early detection of fast-flaming and smoldering fires. Our team evaluates room layout and airflow to determine optimal placement in bedrooms, hallways, and shared living spaces. We also replace aging or damaged units with hardwired, battery-backup models to improve reliability.

Carbon Monoxide Detector Services

Carbon monoxide is odorless, invisible, and potentially fatal—especially in homes with gas appliances or attached garages. We install CO detectors on every level of your home and near sleeping areas to ensure maximum coverage. Our electricians test every device for proper function and integrate them into your home’s power system when possible.

Dual Sensor & Combination Alarms

Some homes benefit from combination detectors that sense both smoke and carbon monoxide. We offer and install dual-function units that reduce clutter while improving overall protection. These are ideal for newer builds or renovations where efficient safety planning is key.

Hardwired System Upgrades

For homes relying solely on battery-powered units, we offer hardwired systems with battery backup for uninterrupted performance. These detectors are interconnected, so if one goes off—every alarm in your home sounds. Our licensed electricians ensure safe, code-compliant installation that won’t disrupt your daily routine.

Detector Testing & Maintenance

Routine testing is essential to keep alarms working properly. We offer inspection and maintenance services that include function checks, battery replacement, and cleaning to remove dust or buildup. If you’re not sure your system is doing its job, we’ll test and verify every unit with professional precision.

Why Homeowners Choose Us

Installing detectors may seem simple—but small mistakes in placement, wiring, or model selection can lead to serious risks down the line. At R.S. Andrews, we take a detail-driven approach to life safety systems, making sure every alarm in your home does exactly what it’s supposed to: warn you fast and without fail. From custom recommendations to expert installation, our team gives you more than just peace of mind—we give you confidence that your home is protected around the clock.

  • Wired right and tested twice: We double-check every wired connection and run live tests to make sure you’re fully protected before we leave.

  • No guesswork, no shortcuts—just code-compliant work: Every detector we install meets or exceeds Georgia’s current building and fire safety codes.

David Rosati was very professional and checked out our new heat pump. He added vibration dampers to help with the noise the system was making and then proceeded to make sure it was working well. This was very much appreciated as we have been experiencing temperatures as low a 8 degrees. I'm always happy when David comes to service our HVAC. Terrell Thomas was very thorough and professional. i was very pleased with his service. He checked out both heat pumps and the three zones in my house and assured me all was working properly, a necessity with 24 degree weather. Both David Rosati and Amber Magnus were exceptional! Amber Magnus was very professional and quite helpful and knowledgeable! David was very thorough and did a great job as usual for R.S. Andrews employees. David explained everything he was doing and I enjoyed the time he spent explaining everything. Terrell did a great job and explained all he was doing and why the capacitor needed to be replaced. i was very happy with him. Nick Husley did a very thorough job. He was prompt, friendly, and answered all questions wel. Nikia was very thorough in checking out the AC system. I feel he was extremely honest in pointing out future repairs that may be needed. Nakia again was very thorough checking out the heating system. Ivan Medina was prompt and thorough in maintaining the AC system. He explained what he was doing and why some part needed to be replaced. He showed me the readings of the failing parts and the readings on the replacement parts.
