CO detectors in Aliso Viejo’s planned communities are required by California law — but the most common CO detector mistake Aliso Viejo homeowners make is assuming a functioning device (lights flash, test button works) is still providing reliable CO protection. Sensor element degradation after 5–7 years means the device may not detect CO even when it appears functional. Here’s what every Aliso Viejo homeowner needs to know.
Pulse Heating and Air checks CO detector status at every Aliso Viejo furnace service visit and advises on replacement when detectors are past their sensor life.
CO Detector Essentials for Aliso Viejo Homeowners
Sensor Life: 5–7 Years from Manufacture Date
The manufacture date is printed on the back of the device — not the installation date or the battery replacement date. Any CO detector over 7 years old should be replaced before heating season, regardless of battery status or test-button function.
Required Locations in Aliso Viejo HOA Homes
California law requires CO detectors outside each sleeping area and on each floor. Interior placement near the furnace (hallway or utility room) is appropriate in addition to sleeping area detectors. At breathing height on the wall, not at floor level.
CO Alarm Response
Evacuate immediately. Call 911 from outside. Do not re-enter until cleared by fire department. Then call Pulse Heating and Air at (714) 908-3868 for CO safety inspection before furnace operation resumes.
