DO NOT SIGN A CONTRACT WITH ADT Listen to their reviews on Google, you don't want to be with this company. When you have problems, you'll find yourself running into long hold times, constant transfers, endless runaround and technicians never actually fix anything. When I tried to cancel service after three false alarms and a technician who didn't fix anything I was informed that I would owe over $900 in cancellation fees, despite being within the first six months of my contract. After a month of asking and a second $59 service fee for a different technician who scratched his head, reset a sensor and didn't fix anything, they finally cancelled my service, but declined to refund me because they didn't fix anything. Dishonest company, stay away. ​

The heart of our faulty security system!

If there was an option to give negative stars I would. Two years ago we had adt installed and it's been nothing but a disaster. The smoke and carbon monoxide alarms go off randomly in the middle of the nignt and we have called to try to have issue resolved not once, not twice but over 10 times!!!! There isn't a person that has been helpful or sympathetic for the trouble this has caused our family. My dad suffers from high anxiety and our dogs are petrified every time the piercing alarms go off. Today, after the alarm going off yet again at the wee hours of the morning, we called to have someone come remove the system from our home. They proceeded to tell us it wasn't their problem because we have "discontinued" our service even though they installed it! And what a beautiful job they did...it's no wonder the alarms are glitchy!!!!

Pat Kerins Electrician

(5 reviews)

It's rare these days to find people with this level of honesty, professionalism, and integrity. Pat…read moreKerins and his father came to our home on very short notice when our air conditioning stopped working. They spent more than three hours in the heat carefully troubleshooting every possible electrical cause. They were incredibly thorough, methodical, and explained everything they were checking. In the end, they determined the problem wasn't electrical at all--it was an issue that needed to be addressed by our oil/HVAC company. Despite spending hours diagnosing the problem and saving us from chasing the wrong repair, they refused to accept any payment. That kind of honesty is almost unheard of today. Many companies would have billed for the time regardless, but Pat and his father genuinely cared more about helping us than making money. They are knowledgeable, hardworking, respectful, and truly exceptional people. I recommend them without hesitation and will be calling them first for any future electrical work. If you're looking for an electrician you can completely trust, look no further.

Pat Kerins electrician are THE BEST. Pat and Steve know their stuff! We were first-time homeowners,…read morebuying an old house and wanted to make sure the original wiring was actually safe now that we had full access to the place. We knew we wanted to hardwire smoke detectors too, but wanted to find someone who give us an honest assessment of what else needed doing and what just could be done. We were getting the runaround with some of the chains but someone on Nextdoor recommend Pat and Steve and when I spoke with them I just felt like they were honest and trustworthy, I'm so glad we booked them! Steve and Pat paid so much attention to our house and helped us understand how the house worked, all the considerations for the things we might want to do, and gave us incredibly fair prices and did excellent work. We've had them back a few times as we have upgraded quite a few things and added new circuits and a new subpanel. They've caught things our house inspector missed and have talked me out of things I didn't need or could do later. Never an upsell, just good honest experts practicing their craft. Our kids love having them over as well--really great guys. A quick story: We wanted to add another ceiling light to our hallway on the top floor, and Pat and Steve drove around to a bunch of old hardware and antique stores and found a nearly perfect match for the other 1930s fixtures--you wouldn't know it wasn't originally there! Just real attention to detail and customer care. Above and beyond.

Thank you so much to OCS for coming out. The whole process was simple, from scheduling, to getting…read morean estimate and ultimately having the work done. Most importantly they came when they said they would, which shouldn't be unusual but is. I really appreciate the honesty the tech provided me (Ken I think it was). He fixed two things with my chimney that a lesser repair person might have tried to upsell me for no reason.

This has to be the most unprofessional experience of any business I've ever encountered. Because we…read morewere not satisfied and were charged over $500 for work not done, my husband and I gave this business a bad google review. (After requesting a refund that was refused). Unfortunately, when you own a business you get good and sometimes bad reviews. The owner was so mad at the review, and that my husband voiced his frustration on his personal social media, she contacted his employer through facebook. She harassed his employer continuously to let her know her feelings about my husband's character and that she wouldn't support her business because of his involvement. She was literally trying to get him fired for bad reviews. I owned a business for 10 years. I got a couple bad reviews along the way about employees work and had requests for refunds. I did so willingly because the customer satisfaction outweighed my ego. I would NEVER call a clients employer after they left a bad review to voice my personal opinion of them. It's absolutely insane that the owner took this route instead of just refunding the money. The owner did offer to have someone else come to do the work but our trust in the company had been diminished. We wanted a second opinion and got one. That's also the prerogative of the customer.
