Green Frontier Electric Ltd

Lazarus was great. Understood what needed to be done and was able to troubleshoot the problem. I will definitely use again when needed in the future. From start to finish a smooth process to get it done and done right!

Our go-to electricians. We’ve used them twice so far, first time to fix burnt connectors with our solar panels that were found during our home inspection, second time was to change a light fixture to a recessed light. Employees are nice, work clean, and are efficient. So far both times prices have ended up being LESS than quoted.

Despite considerable code challenges due to the age of our home, they stuck with it and did a very professional job in replacing our electric panel. We strongly encourage using Green Frontier Electric for all your electric needs!

Would recommend. On time (ahead of schedule). All issues were resolved in a timely manner. No complaints. Will use them in the future for any of my electrical needs.

Caleb is a professional, thoughtful, friendly expert and got the EV charger install done on time and on budget. We look forward to doing solar and battery installation with Green Frontier soon!

Green Frontier was a pleasure to work with. They came out the same day as called. The technician was very personable and knowledgeable. He found and fixed the issue quickly. Very pleasant to do business with.

I highly recommend Green Frontier! I have been doing business with Green Frontier for a few years. They have excellent customer service, they are honest and reliable and have professional and experienced people working for them.

I recently purchased a Tesla and needed a Powerwall installed. After reaching out to several electricians, I decided to go with GFE, and I’m so glad I did! Caleb was incredibly helpful over the phone and offered a very reasonable price. Their process is well-organized, with a technician promptly dispatched to my home. Now, I’m just waiting for the city inspection. The entire experience has been smooth and hassle-free, and I couldn’t be happier with the installation!

Very happy we chose Green Frontier Electric Ltd do fix our electrical issues at our home. Caleb did an excellent job! Their team was professional, efficient, and highly knowledgeable, ensuring everything was completed to the highest standard. They communicated clearly throughout the process and explained the reasons we were having some issues. We highly recommend Green Frontier Electrical Ltd for their quality workmanship and outstanding service! Thanks!

Well like all amateur home improvement junkies. I made a wiring mistake today and created a problem. Called at 130pm they were there by 3pm and fixed my issue and no time. Caleb (spelling) was out tech and is absolutely awesome.

Caleb is fantastic! After working with several different vendors and getting the runaround from most of them, he came in at the last minute and an under a week had came to our property, assess the situation, and provided us the best bid.

I responded to one of their instagram ads and made an appointment to get a level 2 charger install estimate. Nobody showed up at the appointment time that stayed home for, and I didn’t get any response to my emails asking what happened or to make a new appointment. Clearly can’t move forward with this company if they just ghost you.

These guys are great! Would hire Caleb and his crew again for any of our upcoming projects. Highly recommended! Great job Cesar and Calin!

Professional, clean, and punctual. Caleb is easy to get a hold of and is straight forward. They don’t over charge or try to over sell a product you don’t need. Very knowledgeable.

Had a EV outlet installed in the garage. Price was less than I thought and much less than other two quotes.

Caleb answered all my questions and provided valuable advice and recommendations.

Installers were on time and did a great job.

This company will be my first call for any future electrical work.

Caleb and Lazarus were excellent! They are very friendly, professional and honest. They fixed my problem quickly and didn’t charge me for a trip to Home Depot. I highly recommend Green Frontier Electric!

Outstanding work, honest, price and professionalism.

Had a new panel upgrade along with some kitchen remodel activities. Caleb and team were outstanding in every way. If you need electrical work performed, call Green Frontier Electric. They are professional, great work ethics and a pleasure to work with.

I highly recommend Green Frontier, Caleb and his team. I have known Caleb for over 10 years, he is a great guy, I trust him and his work.

Caleb and Ceasar did a great job adding a sub panel, wiring a light in the attic and the heated floor in the bathroom. The price was good also.

The Green Frontier crew is great to work with!! They have changed out our interior lights, replaced the service box and wired my greenhouse, running the wire underground. They do a terrific job at a reasonable cost!! My ‘go to’ electricians!!! 5+ stars!!!

I have had Caleb do the installation of a EV charging station two years ago, he did great job at the time.
Recently, he made himself available to come very quickly to fix a recent issue with it, he did the fix as part of warranty, great customer service!

We originally had a good experience with Green Frontier. But we’re currently in the process of listing our house and found out they never pulled a permit to do the work. They claimed we “denied” getting a permit, but we never signed anything and as the expert you’d think they would have let us know we needed one. Caleb said they leave it up to the homeowner if they want to do the process of a permit or not, which is extremely disappointing to hear. We finally came to an agreement they would pull the permit and have an inspection done, but they’ve completely ghosted us. So now we’re still waiting to hear back and need to have our house listed next week.

Our repair person was on time, quick, professional, and willing to help us with an additional quick job at no cost. He installed a chandelier and replaced light bulbs in our very tall ceilings.

We used Green Frontier for the first time today. It is so nice to use someone with 5 star reviews and have them actually provide 5 star service. We will definitely be using them again!

ALthough I have not personally seen the install, I have seen pic that my son sent me. Looks perfect. My son said the install personnel were on time and professional in their approach to the work at hand. Many thanks.

These guys were great. Everything from the consult to execution of work. Communication was great. They were clean, efficient, and thorough. Will definitely use them again.

Great experience and appreciate a company that
does the work and don’t try to up sale you from the time they enter the front door. Did the work and I thought the invoice was in line with the time and work done. Leaving Green Frontier name and number for the new home owners.

Great working with these guys! Super professional, showed up early, and did a fantastic job hanging 2 fixtures for me on 19ft roof.

Caleb was awesome, came and showed up on time and fixed the problem quickly and expertly. They are the best!

Their old school curtesy, accountability, get it done right the first time culture is unbeatable.
I just had my second interaction with Green Frontier Electric. I am extremely impressed with the knowledge and interaction but even more notably with their genuine intention to complete the work the way I wanted it to be done. I worked with two different electricians on two separate occasions who were both super professional, courteous, knowledgeable and prompt. Thank you Caesar and Lazarus, I will definitely be calling Green Frontier Electric again for all future needs.

I’d give these guys 10/10. Caleb and Lazarus were the two electricians that installed a 30amp circuit for our sauna. Both were on time, highly professional, and clearly experts at their craft. Pricing was very reasonable. Communication was timely. Scheduling was easy. These guys are true pros and it shows thru their high quality work. Don’t hesitate to give them a call!

Great service! I had a 240V circuit wired to a sauna heater and a couple 120V outlets. Quoting and talking through the job was easy, final outlets and conduit run look great. Would recommend!

Caleb was quick to call me and we promptly had a date set up. He removed and then installed a light fixture. He was very very friendly and knowledgeable! Would use Green Frontier again!

Great company. Amazing attention to detail. Had a big job that had to be to code for inspections and they did 100% effort on everything!

Definitely recommend! We had 3 quotes to install EV charger and some standard outlets. This company was by far the most professional and responsive group. Caleb did a great job with the estimate, and Omar and Lazarus did phenomenal work. —will recommend and use again if we need any electrical work.

Great experience! They helped me with a project to install a breaker and outlet for my balcony for my ceramic kiln. They were very efficient and explained what they were doing in a way I could understand. Would definitely recommend!

Green Frontier Electric is a great company to work with. They are responsive, knowledgeable and friendly. They diagnosed my issue in 30 minutes and fixed the problem right away. I would definitely recommend this company to any of my friends!

These folks installed some new style “can” lights (and are doing some other work related to a remodeling project) and wow I appreciate the excellent work of their team. They are fantastic and we would love to work with these people again. Thank you so much!

I recently got a heat pump hot water heater and Caleb at Green Frontier Electric did the electrical work. I also recently had a really bad experience with another contractor on a different project, and had to hire Caleb to fix the errors of the other contractor’s electrician. Thankfully, Caleb was excellent: highly professional, transparent/honest, clean, trustworthy, and reasonably priced. During the inspection, the inspector of 30+ years commented on Caleb’s high-caliber work and use of high-quality parts. I’ll be using him for all home electric projects going forward and highly recommend him to others.

Great work, fair pricing, and they respected my “shoes off” request. Plus, when one small issue arose after the initial work, they promptly coordinated a return appointment to fix it. Very easy to work with.

I've used Green Frontier Electric several times now for some fixture installs and Caleb is amazing. He is in and out and gets things done quickly the right way. Highly recommend!

We had a new service panel installed and a 30A receptacle installed on the far side of the house. These guys are great. Attention to detail was great. The team is very knowledgeable and open to questions. The job ended up more complex than expected...all aspects of the job were completed expertly. Bottom line: knowledgable (made sure we are up to code), respectful, on-time, fair price. Highly recommend!

Green Frontier helped me find a workable solution for my EV charging and garage heating needs. They did a professional job and cleaned up the work site when they were done.

Caleb was excellent with very high quality work. He was timely and skilled obviously a master electrician. Kelsey was very timely with all communications and estimates. The final cost matched his estimate with no hidden costs and he supplied all materials. On a scale of 1-5 I would give this company a 10.

I can’t say enough great things about Green Frontier and highly recommend this place. Caleb was great to work with and is truly a master of his craft. He took his time to analyze my request and approached it with precision and accuracy. I had an office I was updating and he was able to troubleshoot a wiring issue from my builder and corrected it on the spot. I will definitely work with this company again and appreciate the work quality that went into my project. Thanks again!

I have had Green Frontier electric come out on a few occasions and every time they have been nothing short of stellar. This last time was our biggest project with getting an EVSE installed in our garage. Not only were they competitively priced, they also delivered amazing service.

Lazarus was prompt, courteous and installed the EVSE extremely quickly and cleanly. You can tell this was top quality work! I will definitely be reaching out again for future projects.
