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Detectors aren’t designed to last forever—and outdated models can delay alerts or fail entirely when you need them most.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

Called to get an appointment for one of my heating units that was not coming on (during a cold snap). Fortunately I could get an appointment with the technician who performs my routine maintenance, every spring and fall. . My appointment was for a four hour window the next business day. I received a call and a text of my technician, Ivan, arriving at the beginning of that four hour window. After his arrival we discussed the situation. He analyzed the situation and explained to me why the unit was not working properly. A blower motor was not working. Ivan ordered the part(s) and will be installed as soon as they come in. Pleased for a quick turnaround appointment and a quick answer to my concerns. RS Andrews works hard to keep their customers smiling.

From the initial phone call to the actual visit on-site, everyone was professional, kind, and responsive. I was scheduled a same day visit after hours! Ezekiel was quite helpful in not only locating but sharing his knowledge and expertise as he helped navigate my burst pipe and caved in ceiling. He made an overwhelming situation feel like it was going to ok and under control.

This review is based on a home visit. RS Andrews provided a plumbing estimate to my husband yesterday morning. We were very pleased with the experience with our tech, Mohamed. He came out to our home first thing Friday morning and provided a quote for a major plumbing repair. During his time with us he listened to exactly what we needed and provided information for what we specifically asked for without demanding extra unnecessary fees from the client who is already faced with a stressful and expensive situation. He was very polite and knowledgeable during the visit and provided a quick and detailed quote for the requested job. Regardless of outcome of our particular situation, they have gained an ambassador. We appreciate great customer service. I would certainly recommend calling RS Andrews for any plumbing or HVAC needs!

Travon was very knowledgeable and professional. The company however needs more cohesion between electrican, plumber and the timely process of providing estimtes. It's been over a week now and I still do not have a comprehensive quote for HVAC sysstem installation with gas furnace. Competitors have been able to give me a quote upon initial consultation.

Not only is Mohamed a master plumber, he is a very nice and caring individual. When it was discovered that I purchased the wrong type of water heater, and started to get upset, he was calm and reassuring. He went out of his way for us, in many ways. We couldn’t be happier with the service and our purchase of a new water water heater thru Mohamed and RS Andrews and will be a customer for life.

Zoned HVAC was running non stop, not cycling off and one zone was not distributing heat adequately. Terrell arrived as scheduled . He was very thorough in investigating the issues I was experiencing. His troubleshooting efforts identified the problem/resolution which required a part to be ordered. Terrell answered my questions and explained next steps after order placed. . This was my time using RS Andrews. Very satisfied with the diagnostic services performed and the expertise of the technician.

I had my ducts cleaned by RS Andrews. Jose and Jayquon did a fantastic job. They were on time, thorough, respectful of my home, and answered any and all questions I had about the procedure. They cleaned up when finished, leaving no traces of the job behind. I highly recommend this company and Jase and Jayquon.
