Whether you need a single carbon monoxide detector added near your furnace or a complete whole-home system with interconnected sensors, we match the right products to your home's specific layout and risk profile.
Smoke detectors must be installed inside every bedroom and outside each sleeping area. We also install one smoke alarm on every level of the home, including basements. Smoke alarms must be mounted high on walls or on the ceiling because smoke rises, and we follow manufacturer specifications regarding height and clearance to ensure reliable detection. We keep smoke detectors at least 10 feet away from cooking appliances to minimize false alarms, and we position units to avoid obstructions like ceiling fans, air vents, and door frames.
For homes built before 2016, many rooms simply don't have the coverage they need. We evaluate every floor and room, then mount detectors where they'll provide the fastest possible alert.
Carbon monoxide is invisible and odorless, which means you can't detect it on your own. Carbon monoxide detectors should, at a minimum, be placed outside each sleeping area and on every level of the home, and ideally also in rooms with fuel-burning appliances. We install CO alarms in every room with a fuel-burning appliance, including spaces near your furnace, water heater, fireplace, or attached garage. We also place CO alarms near sleeping areas for safety, so your family is protected overnight when CO buildup is most dangerous.
CO alarms should not be placed directly beside fuel-burning appliances unless specifically allowed by the manufacturer. That's why we install CO alarms at least 10 feet from fuel sources to prevent transient readings from triggering false alerts while still catching genuine hazards quickly.
Mount CO alarms at least 4 inches from the ceiling and at a height that still allows easy access for routine testing and maintenance, while following all manufacturer guidance. Our technicians know how to install carbon monoxide alarms in the right locations, so you don't have to guess.
Combination alarms detect both smoke and carbon monoxide in a single unit, which reduces the number of devices on your ceiling while maintaining complete protection. These units are designed with dual sensors that enhance performance by communicating between detection technologies. Tennessee law requires combination units to produce distinct alarm signals so you can tell whether the alert is for smoke or CO.
Combination units are a smart purchase for homeowners who want streamlined coverage without sacrificing safety. We install them in every bedroom, outside sleeping areas, and on each floor, giving your family comprehensive protection from a single, updated system.
If your smoke alarms are more than 10 years old, they've reached the end of their reliable service life. Replace smoke and CO detectors every five years to ensure your sensors respond accurately when it counts. Research has shown that over 40% of CO alarms tested in one study failed to alarm at hazardous concentrations even though their indicators appeared to be functioning normally. An alarm that looks fine on the outside but doesn't work when you need it is worse than having no alarm at all.
We remove your old units, mark the ideal locations for replacements based on current codes, and install modern devices with sealed batteries or hardwired connections with battery backup. If your home has never had interconnected alarms, we can add wiring or wireless interconnection so every device in the house responds together.Whether you need a single carbon monoxide detector added near your furnace or a complete whole-home system with interconnected sensors, we match the right products to your home's specific layout and risk profile.

We remove your old units, mark the ideal locations for replacements based on current codes, and install modern devices with sealed batteries or hardwired connections with battery backup. If your home has never had interconnected alarms, we can add wiring or wireless interconnection so every device in the house responds together.
From your first call to a fully protected home, here's what to expect.
Contact us by phone or online to schedule your assessment. A Coolray technician visits your home to inspect existing detectors, check their age and placement, evaluate your fuel burning appliances and combustion sources, and identify every area that needs coverage. You'll receive a transparent, fixed-price quote before any work begins. No surprises.
We also note any wiring limitations in older homes and present options that fit your budget, whether that's hardwired units with battery backup or high-quality battery-powered alternatives.
On installation day, our technician arrives with all necessary equipment and devices. We mount each unit according to NFPA safety codes and manufacturer specifications. Smoke alarms go on the ceiling or high on the wall, 4 to 12 inches from the ceiling, positioned away from windows, vents, and cooking areas. CO alarms are placed on every level, near sleeping areas, and in rooms with fuel-burning appliances at the proper height and distance from combustion sources.
For hardwired systems, we run interconnect wiring so every alarm in your home communicates. When one alarm detects danger, all alarms sound throughout the house. The process is thorough but typically takes just a few hours for a standard home.
Once installation is complete, we test every single unit. Each alarm is pressed and verified for proper sound and signal. We confirm interconnection by triggering one alarm and making sure every other device in the home responds. We verify audibility in each bedroom and sleeping area so you know the alert will wake you.
Before we leave, we walk you through your system, including how to test each device monthly and when to schedule replacements. We also provide clear information on alarm care and replacement timing. Your installation is backed by our 10-year parts and labor warranty, and our team is available if you ever need follow-up support.

Professional detector installation isn't just about screwing a device into the ceiling. It's about knowing how to choose exactly where each unit needs to go, how your home's layout affects coverage, and what Tennessee building codes actually require. That's where our local expertise makes a real difference for your family.
For a typical Middle Tennessee home, hardwired CO alarm installation generally runs between $100 and $400 depending on the number of units and wiring complexity. Smoke detector installation ranges from about $70 to $150 per unit professionally installed. A complete system for a standard three-bedroom, two-story home with both smoke and CO coverage typically falls in the $600 to $1,200 range. We provide a fixed quote upfront so you know the exact cost before we begin. Compared to DIY, professional installation ensures every device meets code, is placed for optimal coverage, and is properly interconnected.
We offer same-day installation for most requests. If you call in the morning, we can often have a technician at your home that afternoon, so it’s easy to order service and get installation underway fast. Emergency installations are available 24/7. A standard whole-home installation typically takes a few hours from start to finish. Check your local fire department for specific alarm requirements if you're unsure what your home needs, or simply schedule our free assessment and we'll handle the rest with a clear guide to the coverage your home needs.
Every Coolray detector installation comes with a 10-year parts and labor warranty. That covers the devices themselves and the work we perform. If any unit fails or needs service during that period, we take care of it at no additional cost. We also provide guidance on manufacturer warranties, which typically run 5 to 10 years depending on the model.
Absolutely. Installing smoke and CO detectors requires following NFPA safety codes and local guidelines, and our technicians are trained on the current Tennessee building codes, including the International Residential Code and state requirements for CO alarms within 10 feet of sleeping rooms in homes with combustion sources. If your project requires a permit, such as during a major renovation with new electrical work, we handle the process for you. You get complete peace of mind knowing everything is done to code.
Your family's safety shouldn't wait. Whether you need to add carbon monoxide alarms near your furnace, upgrade aging smoke alarms throughout your home, or install a complete interconnected system from top to bottom, Coolray has you covered across Middle Tennessee.
