This was my second experience with CET - the last visit, no work was performed, but I was so impressed with the professionalism of the electrician that I was sure to hire them for this current job. All work was performed quickly and efficiently and for a reasonable price. I will definitely be hiring them again for any future electrical work in my home. I had three projects that needed attention - repair of a kitchen fluorescent light fixture, repair or replacement of a lavatory exhaust fan, and a bathroom ceiling light. 

Business response:

Thanks for the great review. Like your experience, we seek to build long-term business relationships with clients. We have many clients for decades and this strategy helps keep our pricing low because we do not have to advertise. We look forward to your next project !

Chuck, the installer, arrived on time and did an outstanding job. After he finished, he checked to make sure it worked. I have used CET several times before and they rewarded me with a $20 coupon for the next job, but I forgot to use it this time. It was my error, but they still do quality work at a fair price. I needed a breakfast room chandelier that I purchased installed. 

Business response:

Thanks for another nice review. The $20 coupon was for liking us on Facebook and can be used on your next project !

I was having intermittent power outages in my entire second floor for about a month and all it took was about 5-10 minutes for the CET tech to find the source of the problem. Every aspect of the service I received was fantastic. My main issue with getting someone to come out was the intermittent nature of the power outages. If everything is working, they can’t diagnose the problem so timing was key. Well, Leia who provides office support, was absolutely amazing. Talk about excellent customer service! She understood my dilemm... read more

CET office staff was always prompt and thorough regarding our email and phone communications. The electrician who came out to do the work was punctual and highly professional. I also think CET's prices are quite reasonable. I'd definitely hire them again. Replace broken outdoor ceiling fan. Install an indoor dimmer switch. 

Business response:

Thanks for the great (and detailed) review. We hope that you enjoy your new Ceiling Fan !

I called and spoke to Leia to make an appointment because the main panel breaker for the pool pump/pool house subpanel had been tripped and would not reset. Leia took the time to walk me through some steps I could take to try to reset the breaker myself. I followed her recommendations at intervals and eventually I was able to reset the breaker. We really appreciate Leia’s help, especially as one of their electrician would not have been available to come for the next few days. Certified Electric has come to our home to comple... read more

We replaced an old dimmer, and CET after listening to our need, brought the right one for our needs. Second, we had a spot light that worked intermittently. CET checked the socket, replaced it and it still flickered. After looking at the switch plate wiring, it was determined that there was a week signal, and wiring and the switch were replaced. We needed a new dimmer and have short in a spot light repaired. 

Business response:

Thanks for another great review. Apologies for the tech running behind the day of service. We really appreciate our repeat clients some of whom have been with us for decades !

I was so very impressed with Certified Electrical Technologies. Through a series of emails, they were able to walk me through to a solution to my problem. I know that some companies would have automatically just come to my house for a fee. Certified Electrical Technology graciously walked me through the problem at no charge. I will always call Certified Electrical Technologies for any electrical problems. Repair kitchen electrical outlets
