I had a great experience. He came out within 20 minutes of calling, which was amazing. He did the wiring for two indoor fans I was installing and also installed an outdoor fan. He was super fast, very polite, and extremely knowledgeable. The work was done neatly, everything was left tight and secure, and he cleaned up completely before leaving. Highly recommend and would absolutely use him again!

I recently hired Frederick Pereira to install a 240V charger for my electric vehicle, and I can honestly say the entire experience was outstanding from start to finish. Frederick is one of the most skilled and reliable electricians I have ever worked with. From the moment I contacted him, he was incredibly responsive—faster than anyone else I reached out to. His communication alone puts him in a whole different category compared to other electricians I’ve dealt with. When Frederick arrived, he was on time, professional, and very friendly. He took the time to walk me through everything he was going to do with the EV charger installation and explained things in a way that made sense. You can immediately tell he knows exactly what he’s doing. The 240V charger was installed cleanly, correctly, and efficiently. He double-checked all the connections, tested everything thoroughly, and made sure the charger was working perfectly before he left. The level of care and attention to detail he brings is rare today. What impressed me even more was how fair and reasonable his pricing was. I had spoken to several electricians before choosing him, and Frederick’s price was easily the best—yet the quality of his work far exceeded what others were offering. There were no hidden costs, no unnecessary upsells, and no pressure. Just honest, upfront pricing from someone who truly takes pride in his craft. Throughout the entire job, Frederick was polite, respectful, and genuinely pleasant to work with. He treated my home carefully, cleaned up after the installation, and made the whole process completely stress-free. It’s not often you find an electrician who is highly skilled, extremely responsive, very nice, and also the most reasonably priced—but Frederick is all of that and more. If you need any electrical work done—whether it’s an EV charger installation like mine or anything else—I highly recommend Frederick Pereira. He exceeded every expectation I had, and I will absolutely be calling him again for future projects. Finding someone this dependable and professional is rare, and I’m truly grateful for the excellent work he did.

Frederick has been a consummate gentleman at every step of the process. He is clearly very knowledgeable and honorable. He worked with us kindly and answered all questions patiently and comprehensively. He did the work as promised and was very clean. We have already solicitor him to do more work in the future. Can’t recommend Main Service corp highly enough.

I highly recommend Frederick for his meticulous work. The first project was to install an EV charger, and I was impressed by his professionalism and practical approach. He matched to the primary wire color and ran them neatly through the ceiling, securing them to wooden bars instead of leaving them on the attic floor (followed all the wire codes). He skillfully installed the charger on the opposite side of our home, ensuring a tidy exit through the ceiling. Additionally, Frederick took on another project for me, installing two garage lights. His measurements were spot-on, placing the lights precisely in the quarters, which greatly enhanced their external appearance.

Mainservice came out and gave a professional assessment of my situation. I didn’t have work done because my home is old and too many electrical needs for my budget. Thanks MainService for your professional attention and advisement.
