My bad experience with ADT
While ADT's installation and monitoring services were acceptable, my overall experience has been overwhelmingly negative due to its account practices and poor customer service. I canceled my service as instructed and I was required to pay an early termination fee. However, ADT subsequently opened an ADT+ account under my name and address, and began charging a monthly fee starting on February 20, 2026—even though I never activated or used that service. ADT was fully aware that I was selling my home, moving out of Michigan, and would no longer be able to use their service at that property or elsewhere. What is even more disappointing is that I have contacted ADT numerous times to dispute these unreasonable charges. ADT insisted that I activate an ADT+ account to avoid the early termination fee. This requirement was completely unreasonable. I had already sold my home in Michigan, and my new home in California was already protected by another security system. Under these circumstances, I had no need for ADT+ and no practical way to use the service. Requiring me to activate an account solely to avoid a cancellation fee was unfair and unreasonable. After countless phone calls and hours spent repeating the situation, the issue remains entirely unresolved. No customer should have to dedicate so much time trying to stop charges for a service they never used. I have withheld payment on these additional fees, pending ADT's proper investigation and resolution of this matter. ADT's account management and customer support have been unacceptable. Unless ADT promptly removes these charges and improves its practices, I cannot recommend this company to others.

Was hoping for a better interactive experience. One of the window sensor batteries died 2 months after initial installation. Not covered by the warranty. After I removed the sensor and replaced the battery, I tried 3 different adhesives to fixate it back on to the window (command double sided, methylmethacrylate, and gorilla double sided tape) of which none worked. Called ADT and got only mixed answers as to what I should use... Really? Just place some ADT stickers in an envelope and send it to me. Now they want me to act as an off-site technician to repair the sensors. Oh, but wait! For a service contract fee, $100, and additional costs for material, they'll send a tech out!

yay.

Don't waste your money or time with these people. So sorry I went with them.

I currently have a functional alarm system and a monitoring service. However, I was seeking a more economical monthly monitoring fee, which led me to contact several alarm companies, including ADT. My experience with ADT was the least satisfactory among the four. Firstly, their sales representative called me late on a Saturday afternoon while I was attending one event and en route to another. Despite my informing him of this, he continued the conversation. I clarified that I was not interested in a complete alarm system, only central station monitoring if that were an option. He indicated that a sales technician would need to visit my home to provide that information. Secondly, ADT requires potential customers to provide credit card details to secure an on-site estimate. I found this unusual for an estimate, although I was assured the company would not charge my credit card. However, the situation became more concerning when the sales representative informed me that he was sending a series of DocuSign documents for an alarm package and monitoring service, with my credit card intended for payment. When I expressed that I was not interested in proceeding with an inspection and estimate under those conditions, the sales representative became rather unpleasant after I stated my desire to cancel the in-home appointment. He not only persistently questioned my decision but also kept me on the line for several minutes before transferring me to the "department" that could process my cancellation. Once transferred, I was placed on hold for nearly 30 minutes before I ultimately decided to end the call and try again on Monday. ADT is generally regarded as a reputable name in home security; however, their sales team and tactics are, to say the least, questionable and unfair. This was my initial encounter with ADT, and it will certainly be my last.

Extremely disappointing experience with ADT.

I scheduled an appointment to install some equipment and waited over 5 hours for the technician to arrive. After wasting my entire day waiting, I received a call from an employee casually informing me that they would not be able to come and needed to reschedule.

What made the situation even worse is that they tried to reschedule me for Saturday — my only day off, which I dedicate to my home and my children. I already had important family plans, yet my original appointment day was completely wasted for nothing.

After 5 hours of waiting, they simply canceled the appointment and asked me to wait another week for a new appointment.

Very unprofessional service, poor communication, and no respect for customers’ time. I would not recommend this company to anyone, and I am seriously considering switching to another provider that actually values its customers

Terrible customer service! Cancelled my service September 2025 but still have my account open. Previously they were auto billing me and website didn’t allow me to cancel my auto payments! Had to call multiple times to request for auto payments to be cancelled and request my refunds! Refunds have finally been received and now they keep sending me monthly bills to pay for a service I have tried to cancel at least 20 times. They forward me over to various reps and different account managers - NO ONE has been able to fully cancel my account on their end. Just absolutely ridiculous!
