Signs You Need an Electrical Panel Upgrade

Not sure if your panel is due for an upgrade? Watch for these common warning signs:

Flickering or Dimming Lights

Your lights shouldn’t change brightness when the fridge kicks in or you turn on the microwave. If they do, your panel could be overloaded or deteriorating.

Panel Feels Warm or Smells Burnt

This is a major red flag. A hot panel or burning smell can indicate serious electrical issues and potential fire risk. Call us immediately if you notice this.

Breakers Trip Frequently

If you're constantly resetting breakers—or worse, replacing fuses—your panel is likely outdated or underpowered.

Insurance Red Flags

Outdated panels like Federal Pacific, Zinsco, or fuse boxes can raise your insurance premiums—or lead to denial of coverage altogether.

Panel Upgrade Services

Overhead Electrical Service Upgrade (100 Amp to 200 Amp)

We’ll remove your outdated overhead service and install a new 200 amp panel with clean, secure wiring and full ESA compliance. This is ideal for most suburban homes needing more power.

Underground Electrical Service Upgrade (100 Amp to 200 Amp)

Need a low-visibility, underground solution? We handle trenching, conduit installation, and panel upgrades from start to finish—safe, seamless, and up to code.

Sub Panel Installation

Perfect for additions, basement suites, or garages, sub panels expand your capacity without a full main panel replacement. We’ll assess your setup and recommend what’s best.

Labeling Breaker Panel

Confused about what breaker controls what? We’ll label every circuit in your panel so there’s no guesswork during outages or repairs. It’s a small detail that makes a big difference.

Moving Electrical Panel

Renovating or finishing a basement? If your panel is in the way or needs relocating, we handle the move with precision—rewiring, code checks, and ESA inspection included.

EV Charger Installation
Yaroslav did a superb job hooking up our EV charger and was recommended to me by a friend. Pricing was good. He also did other electrical work through our whole home to meet Electrical Safety Authority's inspection ( which wasn't finished by the previous owner who sold us the home). Clean up was amazing as he brought his own portable vacuum. Very well mannered: knocking on doors I had closed before entering. Also making sure I understood what he had to do. Very clear and concise quote and detail of work to be done on each floor. Before I decided to have him take on the permit for the Electrical Safety Authority, the inspector asked who I was hiring and made sure for me that Yaroslav was in excellent standing. He was understanding and tried to be as flexible with me needing to pick up and drop off my kids to school. Highly recommend his work.

For a superb price, Yarik finished the EV charger (with an outlet) installation job very quickly. Response time is quick and was available to do it the week after. Very professional attitude. A high quality job done nicely. I would highly recommend Yarik to anyone!!! Very happy to come across Yarik for this job.

Electrical Panel Upgrade
I hired Yaroslav to upgrade my main panel to 200A. He answered all of my questions along the way, maintained excellent communication from start to finish, completed everything he said he would do on the job-site, and went above and beyond to help me out with installing a new insulated plywood backing for the new panel to mount to. No complaints whatsoever. Thank you!

EV Charger/Panel Upgrade
Yaroslav is truly a pro & was a pleasure to deal with. He offered a competitive rate to upgrade the panel to 200AMP + install a Tesla wall charger. Arrived when promised, communicated well, and job well done. Highly recommended.

Wiring and Rewiring
I’ve had the pleasure of working with Yaroslav from ON Energy on several occasions, and I can’t recommend him highly enough. Yaroslav is an absolute professional — he handled multiple upgrades around my house with exceptional skill and attention to detail. Not only did he complete each project efficiently, but he also took the time to explain his work and offer helpful advice for future maintenance. It’s clear he has extensive knowledge and pride in his work, which made a real difference in the quality and safety of the upgrades. If you’re looking for a trustworthy, skilled electrician, ON Energy and Yaroslav are the team to call!

EV Charger Installation
Professional, easy installation, took his time carefully, little to no disturbance at all. This is what a master class electrician looks like. Yarik is incredibly skilled and had an incredible smooth EV installation. HIGHLY recommend for anyone that needs either EV or electrician work.

Wiring and Rewiring
Yarrik has done two jobs for me and a few for my friends. He does a great job and is very reasonable. There are some greedy contractors who are always screaming "extra, extra" once they start the job and you can't replace them. Yarrik never does that. He is a great guy. I recommend him very highly.

Electrical Panel Upgrade
Great electrician! Hired him to do panel replacement, he picked up the parts, contacted Toronto Hydro (for power shutdown and startup) and contacted ESA to come by and inspect. Wonderful service from start to finish! Do recommend!

Panel Upgrade/EV Charger
Yarik upgraded our home electrical panel to 200A and installed a NEMA 14-50 outlet in our garage for EV charging. I asked him many questions about the cable type he was going to use. He responded with great patience without getting annoyed. I finally accepted his cable recommendation, which he backed up with technical details. Thanks to this, I can upgrade my charger at a later date without changing the cable. Yarik handled all communications, permission, certification etc. and was punctual and efficient. He also made some minor changes I requested without complaining. I have a finished basement, and routing the cable from the basement to the garage was a bit tricky, but he managed to do this with minimal damage. He covered work areas with cloth to protect from dirt and cleaned up everything after work. Yarik and his associate are well trained and the quality of their work is excellent. See how neatly the panel cables are arranged. They were in a messy bunch before. Look no further if you want to do a panel upgrade or an EV charging installation.

EV Charger Installation
Absolutely amazing service and professional installation. From the moment Yaroslav from ON Energy arrived to the time he left, he ensured a clean, efficient, and professional service. He took the time and care to answer questions I had, kept the work area clean/cleaned up any debris, and accommodated any and all requests I had. I would highly recommend him for EV charger installs and based on what I experienced any other electrical service he has to offer. 10/10 on install, cleanup, professionalism, quality, attention to detail.

Modern Homes Need Modern Power

Your electrical panel is the heart of your home's power system. It distributes electricity throughout your home and protects your circuits from overloading. But older panels weren’t built to handle today’s energy needs—let alone tomorrow’s.

From smart home devices and air conditioning systems to hot tubs, electric vehicles, and kitchen appliances, power demand has increased in nearly every home across the GTA. If your panel hasn’t been updated in 25+ years, it’s probably time to upgrade.

Why You Should Upgrade Your Electrical Panel

A panel upgrade isn't just about more power—it's about peace of mind, better performance, and future-proofing your home.

Boost Safety and Fire Prevention

Old panels often fail to meet today’s safety standards. Upgrading your electrical panel significantly reduces the risk of overheating, short circuits, and electrical fires. It also ensures your system complies with Ontario’s current electrical code.

Power for Modern Living

New appliances, HVAC systems, and especially EV charger installations draw a lot of power. A panel upgrade gives you the capacity to run everything without overloading your circuits or tripping breakers.

Protect Expensive Equipment

Low voltage or inconsistent power can damage appliances, computers, and home systems. A properly upgraded panel helps protect your investment.

Add Value to Your Home

Homes with updated 200 amp electrical service are more attractive to buyers and meet the expectations of today’s real estate market. It’s an upgrade that pays off.
