Great! Back in April Mike from Shamrock Electric provided me with power from my basement to my Gazebo and also installed a fan for my wife and I.We will without a doubt recommend him to our neighbors and call on him for our future needs. Thanks Mike!

We have used Shamrock Electric Electric a few times over the last 5 years…. Wiring a new electric oven that replaced a gas oven…. Fixing our high hat in our kitchen… and replacing an outdoor light motion detector … each time Mike did excellent work….Always fair pricing.. We highly recommend Mike and Shamrock and will call him for any future electrical repairs .

Mike Connelly of Shamrock Electric Co. Coordinated the installation of my whole house Generac generator with PSEG long island and my plumber. He connected the automatic transfer switch and fully tested the system upon completion of the install. He has it set to run a test for 10 minutes once a week. My wife and I are extremely happy with the unit and the professional set-up by Shamrock Electric Company .

Michael and Danny did a great job splicing burnt out wires and installing a new electrical outlet outside my house. They also replaced very old switches and outlets for my pool pump and lights with quality materials. They communicated well on times they would come and provided the information I needed to make an informed decision. They also were very today and removed all garbage from my property. Would definitely use them again for my next project!!!

A few years ago, we searched Angie's list for an electrician and found a GEM!!! We have used Mike for several electrical jobs, both at our home and my mom's. We would never use anyone else. He is punctual, polite, accommodating, professional, reasonable, meticulous. Obviously, we cannot say enough. We are sure there are a few adjectives we left out! Thanks Mike once again!

This summer my wife and I put an addition on our home. We used Shamrock Electric for the electrical portion of the job, and we are so glad we did. From the fist time we spoke and throughout the entirety of the job, Mike was always a pleasure to deal with. Mike took the time to listen to what we wanted and how we would be using the new space that we were building. He offered great suggestions and shared Insight from his experience on how to best achieve what we were trying to accomplish. He suggested electric baseboard heat for the new bathroom that ended up being a great money saving alternative to running an extra loop of plumbing in the foundation. We had some delays in the job due to other parts of the construction process, but Mike was always able to adjust his schedule and get to us for the next step when we needed him. That was a huge relief which we appreciated greatly. With all the crews of workers that we had throughout home over the few months the project took, Mike really left the most lasting impression. That’s why we are taking the time to write this review, he made us feel like our job was important to him. All of his work came out great, the recessed lighting, sub-panel, fans, fixtures, HVAC wiring, security lights and even future circuits for landscape lighting all work well and look clean and neat. We would whole heartedly recommend Shamrock Electric, and if we need any more electrical work will will certainly be reaching out to them again.

poorly. installed outlet in the middle of the cabinet for microwave limiting cabinet storage. waiting for outlet to be moved to the upper or lower corner.
Response from Shamrock Electric Co Inc

"Hello [Member Name Removed] Sorry if you’re not happy about the outlet location but it was an existing wire for the microwave and The wire was already sticking out in the back of the cabinet. I hope you were happy that we went back and move the outlet to the right hand side."

This is the 3rd time we've used Shamrock Electric (2nd time in 2 months) for some sizable all day jobs in our home. As always, Mike and Kenny were a pleasure to work with and the work was on time, on budget, extremely well done and neat & clean. Mike makes great suggestions during the estimate and on the job and both he and Kenny are easy to talk to and listen to you. They get our highest recommendation.

Mike and his team are awesome! They upgraded my electric service to 200 amps, installed a new light fixture in my dining room, installed high hats in my kitchen, and replaced a number of other fixtures and outlets around my home. The work was completed in a single day and everything looks great! I've recommended Shamrock to my parents, and will definitely use them for future electrical work.

Michael has been 100% excellent each time we had any work done. Always shows up on time, when he says he will be there, spends time thinking things out to go the extra mile, and does an awesome job, plus it's always at a fair price. Highly recommended.

My experience with Mike and his crew at Shamrock electric, was nothing shy of fantastic. From the beginning walk-through, to the roughing, to the finishing, to the finished product, was easy, reliable and affordable. I am an honest person who has hired a lot of people over the years, and I can say, confidently, that our experience with Mike was terrific. Highly recommended and I will use again.

Mike was responsive with email and text and showed up on time to complete the service. The estimate he provided was what was paid when the job was completed. He walked through what was being completed, gave an estimate of how long the power would be off, and went right to work. The work completed was neat and organized, and they left no mess behind. Work completed was a 200 amp residential upgrade. Would definitely hire again. Mike and his worker were polite and courteous.

I am so pleased with the work Mike did! This is actually the second time I have used his services and have not been disappointed either time. I was having outdoor lighting fixtures replaced and Mike picked them out for me. I love them so much I am going to replace my front porch lighting fixtures with the same ones! I would highly recommend Shamrock Electric for any work you need done!
