When you need us most
Every job — big or small — is handled with the same care and attention to safety standards that keeps your family protected.
Old panels can't keep up with modern living. We upgrade your electrical panel to safely handle today's power demands.
Flickering lights, outdated wiring, or outlets that won't hold a plug? We diagnose and fix the root cause — not just the symptom.
Smart thermostats, lighting systems, EV chargers — we wire and configure the technology that makes your home work smarter.
Before you buy or move in, a thorough electrical inspection uncovers hidden risks and gives you peace of mind.
Recessed lighting, landscape lighting, and ambient solutions — we design and install lighting that transforms your space.
Electrical emergencies don't wait — and neither do we. When things go wrong, we're there fast to get you back to safe.
Mac Electric Company has been a cornerstone of O'Fallon's residential electrical community. We know what it means to show up on time, explain the work clearly, and leave your home as clean as we found it.
Every project we take on is backed by a commitment to safety, quality craftsmanship, and honest pricing — no surprises, no shortcuts. When you call us, you're getting a neighbor who takes pride in doing the job right the first time.
