We understand that electrical service upgrades can be costly. With ACE Electrical & Controls, we will always consult with your hydro distribution company to see exactly how much hydro you are using to assess if a service upgrade is needed. Your hydro usage is the best tell for whether an upgrade is actually required. 

We go the extra mile for our clients in this way, more often than not saving them from spending thousands on unnessessary service upgrades.

Yes. We install Level 2 EV charging stations for both homes and commercial properties throughout Southwestern Ontario. We handle the complete installation by assessing your electrical service and panel capacity, calculating the circuit size, running a dedicated circuit along with installing the Level 2 charger, and topping off the installation with an ESA inspection – so your charger is safe, fast, and ready to go.

We work with all major EV charger brands and can advise on the best option for your vehicle and usage. Contact us for a free quote.

Smart home automation is part of our core expertise – it’s literally built into our name. We install and configure smart lighting, smart thermostats, smart plugs, motorized blinds, wireless switches, and whole-home automation systems that integrate with your smartphone or tablet.

Our automation background means we go beyond plug-and-play. We design systems that are reliable, expandable, and wired properly from the start. Whether you want a single smart switch or a fully automated home, we’ve got you covered.

Industrial work is our niche. We specialize in power distribution, motor control systems, PLC programming and diagnostics, machinery installations, CSA compliance upgrades, electrical thermal image scanning (infrared), power factor correction, heat trace installations, and 24/7 maintenance shift coverage packages for industrial facilities.

On the commercial side, we handle electrical design, energy-efficient lighting and system upgrades, backup power, troubleshooting, and new construction wiring – with a focus on minimizing downtime for your operations.

Response times vary by job type, but we pride ourselves on being genuinely available when you need us. For emergencies, we aim to be on-site as fast as possible – often within hours. For scheduled service calls and project work, we keep you updated on timing and stick to the schedule we commit to.

We also keep you informed throughout the project – no disappearing acts, no unanswered messages. Communication is something our clients consistently praise us for.

No project is too small. We take the same professional approach to a single outlet installation as we do to a full commercial fit-out. Many of our best long-term client relationships started with a small job – that’s how people get to know our work.
