Why Your HVAC Tech Should Install Your CO Detectors
Carbon monoxide comes from the same equipment Bradford already inspects. When we service your HVAC system, we know exactly where CO risks live in your home — and exactly where detectors need to go.
Gas Furnaces
A cracked heat exchanger in your furnace can leak CO directly into your home's air supply. Bradford inspects heat exchangers on every furnace tune-up.
Heat Pumps & AC Units
While heat pumps don't burn fuel, a malfunctioning gas backup strip or attached gas appliance can produce CO. CO detectors near HVAC equipment are critical.
Attached Garages
Vehicles left running in an attached garage are the #1 cause of accidental CO poisoning in the U.S. A CO detector near the garage entry is required by Arizona code.
Water Heaters
Gas water heaters produce CO during normal operation. A malfunctioning or improperly vented water heater can push dangerous levels into living spaces.
Arizona Code Requirements
Arizona follows the International Residential Code (IRC) and NFPA 72 for smoke and CO detector placement. Here's what's required in every Surprise, Peoria, and West Valley home:
- Smoke alarm on every level of the home
- Smoke alarm inside every bedroom
- Smoke alarm outside each sleeping area (hallway)
- CO detector on every level with a fuel-burning appliance
- CO detector near attached garages
- CO detector within 10 feet of each bedroom door
⚠️ Most Arizona homes built before 2010 are not up to current code.
Bradford checks detector placement and manufacture dates during every HVAC service call — at no extra charge.
When to Replace Your Detectors
Check the manufacture date on the back — not the install date.
CO sensors degrade over time. An expired unit may not alarm even with CO present.
Replace when the CO sensor expires, even if the smoke sensor still works.
Chirping = low battery or end-of-life. Don't ignore it — replace the unit.
