LET’S TALK ABOUT YOUR PROJECT
Smoke and carbon monoxide detectors are small devices with a huge job: giving your family the time to get out safely. When they are missing, expired, or poorly placed, that early warning disappears. J&A Pro Electric installs and replaces detectors so your home stays protected around the clock.
Our smoke and carbon monoxide detector installation service includes hardwired and combination alarms, replacement of aging units, and placement based on the layout of the home. We test every alarm before we leave and show you how to maintain the system and recognize its warning signals.

I had a great experience with J&A Pro Handyman and Electric Service! My bedroom door was badly damaged after my dog ran into it and shattered the mirror glass. Joseph and his team came right away, removed the broken door safely, and replaced it with a brand-new one. They handled everything from removal, replacement, and installation quickly and professionally. The door looks perfect now — even better than before. I really appreciate their attention to detail, great communication, and quality workmanship. I highly recommend J&A Pro Handyman and Electric Service for any home repair needs. Reliable, skilled, and very easy to work with!Posted on Google![]()

I have nothing than words of appreciation for the J&A team. They took care of our small bathroom remodeling; they were reliable, cost effective and pleasant to deal with. 100% recommend.
If your detectors are chirping, aging, or missing from key areas, tell us what is installed and we will recommend the appropriate replacement setup. Preparing to sell? An electrical inspection can also review your alarm setup and other visible electrical safety concerns.

Common safety recommendations call for smoke alarms inside each bedroom, outside sleeping areas, and on every level of the home, with CO alarms outside sleeping areas and on each level. We assess your layout and recommend the right coverage.
Most smoke and CO alarms have a limited service life, often around 7 to 10 years. Check the date on the back of each unit, and we can replace any that are expired.
Hardwired alarms run on your home’s electrical system with battery backup, and interconnected models sound together, so a warning in one room alerts the whole house.
Chirping usually means a low battery, an expiring unit, or a fault. If a new battery does not stop it, the alarm may need replacing.
Yes. We replace existing hardwired alarms, including upgrading to combination smoke and CO units.
