When Was the Last Time Your Detectors Were Checked?

Smoke detectors expire after 10 years. CO detectors expire after 5–7. If you’re not sure when yours were installed, our free inspection will tell you exactly what needs attention. Schedule Your Free Detector Inspection

Why You Need Both Smoke and Carbon Monoxide Detectors

Smoke detectors and carbon monoxide detectors help keep your home safe by warning you about danger before it’s too late. A standard smoke detector will not detect CO, and a CO detector will not detect fire. Your home needs both.

  • Smoke detectors look for signs of a fire. Some are better at detecting fast, flaming fires, while others are better at detecting slow fires that create a lot of smoke before flames appear. Some detectors combine both types so they can catch either kind of fire as early as possible.

  • Carbon monoxide detectors watch for a dangerous gas called carbon monoxide. This gas has no smell, no color, and no taste, so people cannot detect it on their own. A carbon monoxide detector measures the amount of this gas in the air and sounds an alarm if it reaches unsafe levels.

  • Combination detectors include both smoke and carbon monoxide protection in one device. They are easy to install and protect your home from both fire and carbon monoxide at the same time. These units usually need to be replaced every 5–7 years to keep working properly.

Warning Signs Your Detectors Need Attention

  • Chirping every 30–60 seconds
  • Weak, muffled, or absent alarm during monthly tests
  • Frequent false alarms
  • Visible damage, yellowing, or dust buildup inside the sensing chamber.

  • Hardwired units losing power or going offline repeatedly

  • Interconnected alarms not communicating
  • Units older than 10 years (smoke) or 5–7 years (CO)

If any detector fails a monthly test, replace it immediately. A non-functioning detector provides zero protection.

Not Sure If Your Detectors Are Still Reliable?

Our free inspection covers every detector in your home—age, placement, wiring, and interconnection. We’ll tell you exactly what’s working, what’s expired, and what needs to change.

Where Smoke and Carbon Monoxide Detectors Should Be Installed

Proper placement is just as important as having detectors. NFPA and International Residential Code guidelines specify exact locations.

Smoke detector placement:

  • Inside every bedroom.
  • Outside each sleeping area (hallways adjacent to bedrooms).
  • On every level of the home, including basements.
  • On ceilings or high on walls, 4–12 inches from the ceiling.
  • At least 10 feet from cooking appliances to reduce false alarms.
  • Away from air vents and windows that could push smoke away from sensors.

Carbon monoxide detector placement:

  • Outside each sleeping area.
  • On every level of the home.
  • Near attached garages (vehicle exhaust is a common source of CO).
  • Within 15–20 feet of furnaces, water heaters, fireplaces, and gas appliances.
  • At approximately 5 feet off the floor (CO mixes evenly with air, unlike smoke).

Most three-bedroom Prescott Valley homes need five to seven smoke detectors and three to four CO detectors for full code-compliant coverage.

What Every Homeowner Should Know About Detectors

  • Smoke detectors expire after 10 years. Internal sensors degrade even if the unit appears functional.
  • CO detectors expire after 5–7 years. Shorter lifespan due to sensor chemistry. Combination units follow this schedule.
  • Hardwired detectors still need battery backup. Replace backup batteries annually.
  • Interconnected systems are far superior. Every unit sounds when any one detects danger.
  • Dust causes 30% of detector failures. Vacuum covers every six months with a soft brush attachment.
  • Battery replacement isn’t always the fix. Chirping often signals end-of-life, not just a low battery.
  • Professional installation ensures code compliance. Building codes specify placement, interconnection, and backup power standards.

Hardwired and Interconnected — The Gold Standard

Hardwired smoke and carbon monoxide detectors with battery backup give your family the most reliable protection. Every alarm sounds together when any unit detects danger—even during a power outage.

Why Professional Installation Matters

Installing, wiring, and interconnecting a code-compliant smoke and carbon monoxide detector system is not a DIY task. Professional installation gives you:

  • Appropriate device selection
  • Code-compliant placement

  • Proper interconnection

Maintaining Your Smoke and Carbon Monoxide Detectors

Monthly

Test every detector. Press the button for 3–5 seconds, listen for a loud alarm, and verify all interconnected units sound together.

Every 6 months

Vacuum detector covers with a soft brush attachment to prevent dust from blocking sensors.

Annually

Replace backup batteries in all hardwired units. Schedule a professional system check covering wiring, interconnection, and code compliance.

Replacement

Smoke detectors every 10 years. CO detectors every 5–7 years. Combination units every 5–7 years. No exceptions.

Frequently Asked Questions

Current code requires smoke detectors inside every bedroom, outside each sleeping area, and on every level of your home including the basement. Most three-bedroom Prescott Valley homes need five to seven smoke detectors for full coverage. Hardwired interconnected systems are recommended so all alarms sound together, giving everyone in the home maximum warning time.
Smoke detectors should be replaced every 10 years, and carbon monoxide detectors every 5 to 7 years, regardless of whether they appear to be working. The sensors degrade over time and become less reliable. Check the manufacture date printed on the unit. If your detectors are nearing these ages, schedule a replacement with a licensed electrician.
CO detectors should be installed on every level of your home, inside or near every sleeping area, and near any fuel-burning appliances such as furnaces, water heaters, gas stoves, or fireplaces. In Prescott Valley, many homes use propane or natural gas for heating, making CO detection especially important during winter months when furnaces run frequently and homes are sealed tightly.
Hardwired smoke and CO detectors with battery backup provide the most reliable protection. They receive constant power from your home’s electrical system and include a backup battery for power outages. Most importantly, hardwired units can be interconnected, meaning when one alarm detects smoke or CO, all alarms in the home sound simultaneously. Battery-only units operate independently and may not alert people in distant rooms.
CO detectors should be installed on every level of your home, inside or near every sleeping area, and near any fuel-burning appliances such as furnaces, water heaters, gas stoves, or fireplaces. In Prescott Valley, many homes use propane or natural gas for heating, making CO detection especially important during winter months when furnaces run frequently and homes are sealed tightly.
Professional hardwired smoke and CO detector installation in Prescott Valley typically costs $100 to $250 per unit, including the detector, wiring, and labor. Replacing existing hardwired units is at the lower end, while installing new hardwired units where only battery detectors existed previously costs more due to wiring requirements.
