Unfortunately I switched from Vivint to ADT two years ago. I was sold on their brand promise that…read morethey would provide better service and I will say that their technicians are really easy to work with. They went above and beyond each time they came to my house. However, they had to come often because our panel needed resetting and our camera doorbell's connection was off quite often. So, you will need technicians at your house at least every 3 months I found. Also he camera is lagging and rarely would pull up on my phone when I was away from the house. But the worst part was trying to transfer the service when we moved. We moved and didn't need a alarm system in our new home and when we tried to transfer Vivint to the new owners they wouldn't honor the transfer. They set the new owners up with a NEW account and told me they couldn't do anything about it. Even though the new owners set up an account with Vivint because of me, they still told me I would have to pay the 3 years cancellation fee left on my 5 year contract. This was after I already paid off my equipment. It gets worse. When the new owner tried to call in to transfer, the representative told her they don't do that kind of thing and that she would have to set up a new account. They told her that again when she tried to call back in after I explained the issue. So, Vivint lied to the new owner so they could keep my account and get a new one. Unfortunately, they have lost their customer service centered value and are prioritizing profits over customers. The sad part is I was a somewhat happy customer and advocated for them with the new owner. All they had to do was transfer my $42/mo to her. But instead I was on the phone for 4 hours on 12/23/25 (yes, the day before Christmas eve) trying to figure out why they couldn't just transfer or combine the accounts. They escalated me to their supervisor and he also wouldn't help. In fact, he told me the only way is if the new owner called the specific transfer number. When she did, they again told her they don't do that sort of service. DO NOT GO WITH VIVINT. They are not customer focused and in fact lie and conduct shady business.

Very professionally, Keith inspected my old unit and gave me a very reasonable quote on the spot. Originally, my wife and I were going to shop around for the best price but I decided to give them our business because of the price (including parts, labor, military discount, everything else) and timeliness. Keith offered to come out the very next day. His employees arrived first thing in the morning and worked through a heavy downpour. They were very courteous and mindful not to track mud in the house and offered to clean the floors as they worked. The guys even offered to seal a leaking radon vent on my roof that i just found (That had absolutely nothing to do with my air conditioning) for free. They all were very professional and did a phenomenal job for an unbeatable price. I will HIGHLY recommend their services to anyone I know!!!
