Carbon Monoxide & Smoke Detectors

Carbon monoxide (CO) and smoke detectors are life-saving devices that protect your household from deadly threats. However, in order for them to be effective, they must be correctly installed and maintained to ensure they function properly when needed..

While smoke is much easier to see and smell, carbon monoxide is a deadly odorless, colorless, and tasteless chemical compound that can only be detected by a carbon monoxide detector. To make your life easier and safer, we provide carbon monoxide and smoke detector services that include the installation of an all-in-one smoke and carbon monoxide detector for your home or business.

We treat our carbon monoxide detector installations and smoke detector services as if lives depend upon them—because they do.

What Causes Carbon Monoxide in a House?

Carbon monoxide detector installation is critical for homes and businesses because there is no other way to detect this gas. Known as a “silent killer,” this gas is a byproduct of combustion, which occurs daily in many homes and businesses. Here are some common sources of high levels of carbon monoxide:

  • Faulty furnace
  • Use of a Fireplace
  • Gas-powered: generators, refrigerators, lamps, stoves, etc.
  • Faulty water heater
  • Pellet and wood stoves
  • Fumes from a car, truck, tractor, or other gas-powered motor

Inhaling high levels of carbon monoxide, even for a short time, can result in cardiac arrest, brain damage, and death. Protect yourself and your loved ones with Aire Serv’s carbon monoxide detector service. One of the leading causes of a carbon monoxide leak is a faulty furnace. Our team of local experts will provide twice-yearly HVAC tune-ups to ensure your system is operating safely and efficiently. Avoid carbon monoxide leaks and keep your system working at peak efficiency, which will save money on your monthly energy bills.

What to expect during our carbon monoxide detector service:

  1. Test to ensure existing carbon monoxide detectors are working properly.
  2. Review the floor plan to determine if additional carbon monoxide detectors are necessary.
  3. Check your HVAC system for leaks and ensure it’s working efficiently.
  4. Discuss a maintenance plan to keep your system operating efficiently.

Professional Carbon Monoxide and Smoke Detector Installation

We recommend installing a CO detector on each floor of your home (including the basement) and in each sleeping area. Whether you’re building new, adding on, or bringing your space up to code, our teams are here to help you select, install, test, and maintain your smoke and carbon monoxide detectors.

Carbon Monoxide and Smoke Detector Installation and Replacement

According to the US EPA, “Each floor of the home needs a separate detector.” It is also recommended that a detector be placed in every sleeping area. Therefore, proper carbon monoxide detector installation is crucial to ensuring you get the full protection a carbon monoxide detector provides.

Reliable Carbon Monoxide and Smoke Detector Replacement

According to many manufacturer guidelines, carbon monoxide detector replacement should be performed at least every five to seven years. Smoke detector replacements should occur every 10 years on all models. When replacing your carbon monoxide and smoke detectors, a member of our team will review the timeline for future inspections and replacement.

Smoke and carbon monoxide detectors do eventually wear out. It’s essential to replace your detector’s batteries and test the unit at least twice a year, regardless of function—many households choose to do this at the start and end of Daylight Savings Time.

We also recommend having your carbon monoxide and smoke detectors professionally inspected once a year.

Carbon Monoxide and Smoke Detectors FAQs

As an industry leader and a brand that is trusted by homeowners and businesses nationwide for our knowledge and experience, we’re happy to answer your questions. Here are answers to some of the frequently asked questions about smoke and carbon monoxide detectors.

Yes, but only if a combination smoke and carbon monoxide detector is installed. Smoke detectors detect smoke particles and heat. In contrast, carbon monoxide detectors monitor for carbon monoxide (CO), a gas that's odorless, colorless, and dangerous in high concentrations. If your smoke alarm is meant to detect smoke, it won’t let you know if there’s CO in the air. If you're unsure what’s best for your family’s needs, consult an HVAC professional.

This depends on your home’s layout,  budget, and protection needs. Separate detectors allow for optimal placement of each type, ensuring maximum detection accuracy. However, combination detectors offer space-saving benefits and fewer devices to maintain, and they are ideal for smaller spaces or for simplifying installation and alerts.

Some combination detectors have advanced features like voice notifications to specify whether the alarm is for smoke or CO. No matter what you decide, having smoke and carbon monoxide detectors is crucial for your family’s safety.

Smoke rises, so it makes sense to install smoke detectors on ceilings or high on walls in every bedroom, outside sleeping areas, and on each home floor, including basements. Avoid placing them near windows, doors, or air vents to prevent airflow from interfering with detection.

Since CO mixes evenly with air, carbon monoxide detectors should be installed approximately five feet from the floor or higher. Place them outside sleeping areas, near fuel-burning appliances, and on every level of your home. To avoid false alarms, avoid installing them directly above fireplaces, stoves, or other combustion appliances.

A carbon monoxide alarm will sound when dangerous levels of carbon monoxide are present. Common causes include malfunctioning furnaces, water heaters, stoves, or fireplaces. Poor ventilation can also lead to CO buildup. Additionally, running vehicles or gas-powered equipment in enclosed spaces like garages can produce CO that seeps into your home.

Do not ignore the alarm. Evacuate immediately and call 9-1-1 as CO exposure can be fatal. Once the acute threat is resolved, contact an HVAC professional like your local Aire Serv to reset your detection system.

If this happens, it means there's carbon monoxide in your home—not smoke or flames. Evacuate immediately, and call 9-1-1. Do not re-enter the home until an emergency services professional (usually fire department personnel) has inspected and cleared it. Keeping your carbon monoxide detectors in good shape is key—make sure to test them regularly and replace the batteries when needed.
