Just fine. The technician arrived early within the agreed time frame and was courteous, professional and friendly. He took very little time to correct the problem and made sure everything worked. We have a very old house with an outdated original electrical system, and we will definitely have CET back for other problems as they arise, as they are familiar with old homes like ours (ca. 1911). Some of our problems cannot be solved without tearing out walls, apparently, but this one was quickly fixed! A dimmer switch which was ... read more

It turned out it just needed new bulbs, but I didn't know how to get the fixture open to replace them. The workers from this company are always polite and thorough. Yard light didn't work

Jessie, Did a great job and I would definitely hire him again. My only problem was that I had to wait 5 days for them to come out to do the work. I guess these companies just get busy. I also was told that he would give me a 30 minute window and it took a bit longer than that. not a big deal but would have preferred him being there sooner. needed 5 smoke detectors installed in a condominium 

Business response:

Thanks for the nice review. Summer is our busy season and depending on area it can take several days to get an appointment. Thanks for your patience !

Yesterday we lost power to our internet, phone and TV as well as to a couple of lights in our basement. I was desperate and called Certified for emergency service primarily because they had been at our home on several previous occasions and completed work in a timely and professional manner so I trusted them. When I called to explain the problem, the issue was diagnosed over the phone and a solution proposed that enabled me to fix the problem without requiring an electrician coming to the house. Not only could I do the fix m... read more

Thanks for the great review and posting it on both AL and Bird Eye which aggregates all of our online reviews from AL, Yelp, Google, Checkbook, etc. We have over 2000 positive reviews ! We receive several calls each day like this one where our highly experienced service managers answer questions and solve problems over the phone. Unlike other firms that focus on generating revenue and want to run as many service calls as possible, we focus on the customer experience. If we can resolve an issue over the phone, we are happy to... read more

I called Certified Electrical Technologies on 5/23/18 and spoke to "Leia," who was helpful in setting up an appointment for the following week on Wed, May 30th between 9 AM - 1:00 PM. On the day of my service, I received a call from "Eric," their technician, to let me know he was on his way to my home; he arrived 10 minutes later. When Eric arrived, he quickly began removing the old ceiling fan in my dining-room, he answered all my questions and he replaced the new fan within an hour's time. He was professional and skilled i... read more
