CO & Smoke Detector Installation, Replacement & Testing
Treviño Repairs installs and replaces smoke and carbon monoxide detectors the right way—proper locations on every level and outside/inside sleeping areas, clean wiring, and interconnection so all alarms sound together. We assess your layout, confirm power source (hardwired with battery backup or sealed battery), add or reuse circuits when appropriate, and install combination units where they make sense. After mounting, we label install dates, test with the manufacturer procedure, review simple maintenance (monthly tests, battery checks, typical 7–10 year replacement cycles), and can provide smart/monitored options when needed—so your RGV home or business stays code-compliant and protected.

CO vs. Smoke Detectors—Placement, Power & Replacement
Smoke detectors sense particles from fire, while carbon-monoxide (CO) detectors monitor an invisible, odorless gas—so you need both, placed correctly and interconnected to alert the whole home. Best practice is hardwired with battery backup (or sealed 10-year battery where wiring isn’t feasible), with smoke alarms on ceilings or high on walls in bedrooms, hallways, and every level; CO detectors near sleeping areas and by attached garages (but away from kitchens, ducts, or steamy baths). Test monthly, keep vents and sensors clear of dust, and plan timely replacement—typically about 10 years for smoke and 7–10 years for CO, per manufacturer guidance. Treviño Repairs verifies locations, wiring, and interconnection, then labels dates and reviews simple upkeep for your RGV property.

When to Replace or Upgrade CO & Smoke Detectors
If your alarms chirp even after a fresh battery, fail a monthly test, or only some units sound during an interconnect test, it’s time for service. Detectors past their lifespan (smoke ~10 years; CO ~7–10 years per manufacturer), frequent nuisance alarms, yellowed/corroded housings, missing battery backups, or changes to your home—new bedroom, finished space, attached garage, or new gas appliances—also signal a needed upgrade. Treviño Repairs can verify locations to current standards, test wiring/interconnects, add or relocate devices, label install dates, and set you up with reliable protection for your RGV home or business.

Great Service: We had a leak and couldn’t figure out where it was coming from. Eduardo took his time to find the source, kept me updated throughout the process, and finally discovered it was an AC leak. Just last week, we had paid another company to fix the same issue, but they didn’t do the job correctly. Eduardo explained everything clearly, offered to correct the problem, and even charged less than what we had previously paid the other company. Once he identified the leak, he made sure it was completely taken care of. I called today, and they arrived in less than an hour—excellent service! Eduardo was the best, and I highly recommend him company.Posted on JoAnn BreauxTrustindex verifies that the original source of the review is Google. Great service, super fast and convenient.

CO & Smoke Detector Questions, Answered
Straightforward answers before you book—symptoms, costs, fixes.
Do I need both smoke and CO detectors, or are combo units OK?
You need protection for both hazards. Combo units are fine when properly placed and powered; in some layouts, separate smoke (bedrooms/halls) plus CO near sleeping areas and by attached garages is the better fit. We’ll recommend the right mix for your home.
Hardwired or battery-only—what’s best?
Best practice is hardwired with battery backup for whole-home interconnection. Where wiring isn’t feasible, sealed 10-year battery models are a solid option. We verify power sources and interconnect so all alarms sound together.
How long do detectors last?
Most smoke alarms are about 10 years and CO detectors 7–10 years—always follow the manufacturer’s date code and guidance. If yours are past that or yellowed, replace them.
Why does my alarm chirp after changing the battery?
Chirping can mean end-of-life, a weak/incorrect battery, dust in the sensor, or wiring/interconnect issues. We can test, clean, verify power, and confirm if replacement is due.
Where should detectors be installed?
Smoke: on ceilings/high walls in every bedroom, outside sleeping areas, and on every level. CO: near sleeping areas and by attached garages (away from kitchens/steamy baths). We place and label units to current standards and test that all alarms sound together.
