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Detectors aren’t designed to last forever—and outdated models can delay alerts or fail entirely when you need them most.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. Atlanta homeowners trust us to treat safety like it’s personal—because it is.

  • We treat every home like it’s protecting our own: Your family’s safety drives every decision we make on the job.

  • Tailored recommendations—not one-size-fits-all: We look at how your home is built and how your family lives before recommending devices.

  • 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.

  • Trusted in Atlanta homes for generations: Our reputation is built on protecting people, not just wiring systems.

Brandon is an excellent plumber and his work is of the highest quality. Nevertheless, the price I had to pay for the service was very high.

Brian did a great job and was very respectful.The only reason I didn't use the service is because it's just too expensive. It shouldn't cost $534.00 to replace a simple garbage disposal that cost about a $130.00. He does not set the prices though so I do not fault him personally! If I had a more complex issue going on something that required real plumbing expertise, I would have definitely considered using Brian and RS Andrews if they were somewhat competitive with their pricing.

Brennan Pilson and his crew repaired my sewer lines and replaced my 2001 water heater and expansion unit. Brennan completed and managed the projects very well. He double checked the work while it was in progress to make sure it was accomplished correctly. I was informed about the work during every major step. I really appreciate Brennan's professionalism, expertise and consideration of my needs while the work was in progress.

R. S. Andrews is my favorite for reliability and top notch technicians for heating and cooling. Anthony came out to solve my heating problem today which was linked to a faulty circuit breaker. He fixed the problem, answered all my questions, proposed options for improving air quality in the house, and was so friendly. Loved that he had exactly what was needed to fix the problem on his truck. Gold star service! Bravo!

Anthony French and his colleague came to my house this week for a standard A/C service check. They discovered two issues that needed attention and came inside to tell me. I gave them permission to proceed on both of the items because I knew nothing had ever been done to the outside A/C unit. They were able to perform the tasks. Anthony and his colleague were both very professional and polite. It was a pleasure having them perform the service call.

Henry and his crew did a terrific job installing two new Lennox HVAC systems in my home. All the installers were very polite and careful and worked very hard to make sure that everything was perfect. They explained what they had done, and ensured that I was completely satisfied with the results. Daniel Magnus was the salesman who determined the equipment best suited for my needs and suggested that changes in the ducts would solve some heating issues. His recommendations were right on target. I highly recommend RS Andrews. My only regret is that I did not call the company sooner.
