Hi-Lite Electric provides professional smoke and carbon monoxide detector installation, replacement, and service throughout Arlington Heights and the surrounding Cook County communities. We are a family-owned electrical contractor with the training, equipment, and local knowledge to handle detector work the right way, whether you need a single unit replaced or a whole-property system brought up to current code.
When you reach out to Hi-Lite, we start by understanding the scope of what you need, and for most detector installations or replacements, an on-site visit to Arlington Heights allows us to assess existing wiring, detector placement, and any interconnection requirements before we put together an accurate project quote. Once we have a clear picture, we schedule at a time that works for you and arrive prepared to complete the work efficiently, without leaving a mess behind. Our electricians are continually trained on current code requirements so that every installation reflects what inspectors in Cook County expect to see.

Arlington Heights has a large inventory of post-WWII ranch homes and split-levels where original wiring and older panels are still common, and a detector installation visit often opens up a broader conversation about what else might need attention or what projects are on the horizon. Our team at Hi-Lite is happy to serve as a sounding board for future upgrades, whether that is expanding your electrical panel service or planning an EV charger installation down the road. We want to be the electrician you call first, not just the one you call when something stops working.
In many cases, Illinois building code and local Arlington Heights ordinances require hardwired, interconnected detectors with battery backup in new installations and certain replacement scenarios. An on-site visit is the best way to confirm what your specific property requires before any work begins.
Most manufacturers recommend replacing smoke detectors every ten years and carbon monoxide detectors every five to seven years, regardless of whether they appear to be functioning. If your detectors are original to an older Arlington Heights home, replacement is almost certainly overdue.
The project quote depends on the number of units, whether new wiring or interconnection is required, and the scope of the overall installation. We assess the situation before providing an estimate so that the quote you receive reflects the actual work involved.
Scheduling depends on current workload and the nature of the request, but we do offer 24/7 availability for situations that require prompt attention. For standard installations, we work to get you scheduled as efficiently as possible.
