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Detectors aren’t designed to last forever—and outdated models can delay alerts or fail entirely when you need them most.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.

RS Andrews sent their HVAC Technician Jonathan Balom who did an amazing job of serving our A/C unit that was blowing hot air on short notice. He replaced the worn out capacitor with a new one, so we didn't have to replace our old A/C unit. RS Andrews is a trustworthy company that I would recommend for Heating, Cooling, Plumbing and Electrical issues. Thank God I heard about these guys from the radio ads because what they say delivering smiles is true. They definitely delivered a smile for us.

RS Andrews has surpassed all my expectations for quality work, experienced team members, and prompt attention to my requests. Amber Magnus, my sales rep, was personable, efficient, and professional. She took the time to answer all my questions and to help me understand what work needed to be done to install a new HVAC and why. The installation crew was just as knowledgeable, personable, and worked together efficiently, with great attention to protecting my home. I commend this company for their focus on customer service. It is becoming more and more rare in today's environment.

Excellent! Jose was our technician and he was GREAT. Very personable, knowledgeable, and hardworking. It was clear he knew exactly what he was doing. His assistant, Justin, was also great. They replaced the booster fan and other piping in our laundry room. They left the laundry room very clean and then took time to answer our questions and review their work. Highly recommend.

Since the first day I contacted RS Andrews, the service has been top notch! From the attentiveness of the customer service person responding to the calls, to Thomas who came out for the repairs. Thomas was such a breath of fresh air! He was kind, knowledgeable, informative and did an absolutely amazing job identifying where the plumbing issue came from, to the actual repair. I was bracing for an astronomical price, but GOD!! Thank you RS Andrews for who you are and how you care for your customer base🙏🏽.

Paul Creel is a great representative of your company. Paul did a repair of the main water line coming into my residence. He explained the work process and provided me with an estimate. The work was completed in a timely and professional manner. I am very satisfied with the work and clean up of the area. I will recommend your company to friends and family. WT 8/14/2025

My home is 15months old. Built May 2024. I had issues with my air beginning June 2025. All maintenance was up to date. Called the original company that installed my HVAC system. 5 visits later still wasn’t fixed. They just kept “trying” things. My system froze again this time causing a water leak. Terrell T came out and asked questions and did adequate troubleshooting and within 30 minutes my air was cooling. He even followed up with me to make sure we were still good! Will definitely use them again.

Called out RS Andrews to get a plumber to diagnose my leaking Kitchen sink. Robert H came by and did an awesome job. He explained everything that was going on, was very knowledgeable, verified the water pressure at the PRV and recommended everything needed to get me back up and running. Thanks for the service!

I had a fantastic experience with Max Borrelli for the installation of my home EV charger. From the start, he was professional, punctual, and clearly knowledgeable. He walked me through the process, answered all my questions, and made sure everything was up to code. The installation was done efficiently, neatly, and with great attention to detail. It works perfectly, and I couldn’t be happier. Highly recommend to anyone needing electrical work, especially for EV setups!

This was our first experience with RS Andrews, and it was positive across the board. Scheduling was easy, communication was perfect, and the work done was top-notch, The tech (Terry Winfrey) arrived when promised and he obviously knew what he was doing. He found a 44-year-old A/C unit with several issues and repaired them all. Plus, he is a nice person who was easy to talk with. I am very pleased with my interaction with R.S. Andrews would use them again and recommend them highly to anyone. We just had another visit from R.S. Andrews, and it was yet again a very positive encounter. The tech, Calvin Russell, showed up on time and fully prepared for the job. Mr. Russell was friendly, professional and easy to talk to. He performed all needed work with skill and expertise. Especially remarkable was that he did not at all mind answering any questions and explained technical details in an easily understood manner. As a homeowner, I really appreciated that. Calvin Russell is an outstanding representative for R.S. Andrews, and we would not hesitate to have him work on our HVAC again.

    Heater on the fritz? Frustrated with plumbing problems? R.S. Andrews is just a call away!
