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Detectors aren’t designed to last forever—and outdated models can delay alerts or fail entirely when you need them most.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

This is the second time I have used RS Andrews and was very satisfied again. Brennan was the tech who visited our home. He thoroughly explained why I was having the problem I had, gave me choices on what I wanted repaired or replaced and performed the work professionally. Will definitely use RS Andrews again and will request Brennan.

We had a new Lennox HVAC system installed in our home. The RS Andrews sales team, technicians and service staff were super...patient and kind. I can't say enough about the technicians. We have an older home and the installation had its challenges...working in the attic and outside. They were well-trained and were able to get it installed in a timely manner.

Victor's name was not listed on the initial site to leave a review. I'm not sure why. He was very knowledgeable and a really nice guy. The 5 stars is for our experience with him. Unfortunately for us, the diagnosis is a shot compressor, which meant we have to be handed off to someone else. While we were shocked and surprised to get a same day visit on the Saturday of Labor Day weekend, Victor called in our request for the next step. Despite the information that we have someone in the house with a medical condition that will out her in the hospital should she get overheated, I am sitting here at 10:10 at night not having heard from anyone. I understand that it is a holiday weekend, but we were kind of left thinking that it would not take long for us to hear from someone - even if only to schedule the next step - so that was kind of a bummer. Nonetheless, I am still quite pleased with the lady who took my call this morning, the fact that we were even able to reach someone on a holiday weekend, that we got a same day visit on a holiday weekend, and our experience with Victor - and that counts for a lot despite the less-than-ideal ending to today's story.

My water heater broke unexpectedly and I called RS Andrews for a quote. Due to some faulty valves in the house I had to turn the water off at the street. Their plumber, Eric Sanchez, came as soon as possible and stayed until the job was done even though it was well after working hours on a holiday weekend. The price was very reasonable. Will definitely recommend this company in the future. Eric, thank you for working late to get the water back on for my family!

I had my annual AC maintenance completed by Calvin Russell from RS Andrews, and I couldn’t be more pleased with the service! Calvin was professional, knowledgeable, and took the time to clearly explain everything he was doing. He identified that my capacitors needed replacing and handled it quickly and efficiently, making sure my system will run smoothly through the season. What really stood out was his friendly attitude and attention to detail—he made sure all my questions were answered and gave me peace of mind about the condition of my AC unit. It’s not every day you find a technician who combines skill with such great customer service. If you’re looking for a reliable, courteous, and thorough technician, I highly recommend asking for Calvin Russell at RS Andrews.

Awesome service. James May was service man and he did an excellent job. He explained what was wrong (I had low water pressure but didn't understand how that happens) and what the cost would be. He worked until it was fixed properly.

"Our technician(Charlie McQueen III),was a lifesaver! We had a confusing A107 error code on our new Rheem hybrid water heater after it was installed because the leak sensor got wet. Charlie diagnosed the issue immediately, and was incredibly patient and knowledgeable. He thoroughly explained how the system works and what we needed to do to get the sensor completely dry. Thanks to his help, we were able to clear the error code and get our unit running perfectly. Highly recommend!

Smelled a slight gas leak and repairman Ivan Medina performed leak search on gas line connected and discovered leak at the flare on flex line. He replaced flex gas line and rechecked for gas leak. No gas was detected after replacing line. Repaired under warranty so no charge. Many Thanks, James ( a very satisfied customer).

Had a tremendous experience with RS Andrews and Keyshawn J. We had another company out to check a problem after a leak and they reported back "nothing wrong except your system is old and needs a replacement". Then 24 hours later the system stopped working. Called RS Andrews...they sent Keyshawn the same day...then he proceeded to not only diagnose & fix the problem, but assured us our unit still has a little life left. AND RS Andrews didn't even charge us for the visit because they have a "free second opinion" policy. Will definitely be contacting RS Andrews when it's time for a new system. Appreciate the great service and Keyshawn was helpful, polite, explained everything in detail & earned our trust.

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