He also updated our key pad program and showed other features the security app too. If this is not top notch customer service then I don't know what is.

I have been a customer of San Marino Security for the past 7 years. They designed a system based on…read moreour specific needs and completed the installation professionally and on-time. I was very specific about certain aspects of the installation and they graciously accommodated all of my requests. This week a great technician named Vic came out to our home to replace all of my batteries and update the firmware on my system. He was very friendly, efficient, and informative. He explained everything to me and made the process incredibly fast and easy. I could not ask for a better experience. I appreciate how responsive San Marino Security has always been to my needs. They always respond very quickly and their customer service really stands out from most other companies. I can't say enough good things about them. I have referred many friends and family to them and everyone has the same experience. I highly recommend San Marino Security.

Tim is hands down one of the best service professionals I've ever worked with. From the moment he…read morearrived for our installation, it was clear he takes immense pride in his work & genuinely cares about his customers. He didn't rush a single step. Tim was thorough, meticulous and incredibly patient...explaining every detail, double checking everything and making sure the system was not only installed perfectly but tailored to our needs. He went far beyond what was expected, answering questions we didn't even know to ask and making sure we felt completely confident before he left. What really stood out was his attitude. He is/was professional, kind, and genuinely invested in making sure everything was done right. That level of care is rare these days and it made all the difference! Because of Tim, our experience was outstanding! He is a true asset to the company and if you're lucky enough to have Tim as your technician, you're in excellent hands.

The Gold Standard for West Hollywood West…read more After a traumatic burglary involving tech-savvy thieves, I realized standard wireless systems weren't enough. I switched to Post Alarm Systems, and the difference is night and day. * The Wired Advantage: Unlike wireless setups, Post's fully wired system can't be easily jammed. It's robust, reliable, and professional. * Armed Patrol: This is their "secret sauce." Their local armed response is incredibly fast. They know the neighborhood, understand LAPD/Sheriff protocols, and provide a physical presence that national chains simply can't match. We were the first in our neighborhood to switch, and many neighbors have since followed. If you want a local partner that provides actual security--not just a sticker in the window--Post Alarm is the only choice.

DO NOT USE THIS COMPANY…read more - We hired Post Alarm in Arcadia, Calfironia to install an alarm system which they did and to conduct daily perimeter walks of our property. As part of the daily perimeter checks, we specifically requested that newspapers be picked up and placed at the front door. Glenn sold us the system, and we later dealt directly with Rob regarding ongoing concerns. The last time we raised this issue, Rob gave us his word that it would be resolved. It has not been resolved. We visited the property today and found clear evidence that the agreed-upon services are not being performed. The pictures speak for themselves. This is apparently how this company treats clients when they believe there is little to no oversight. This is a complete breach of trust. We are being billed for services that are simply not being provided. There is no excuse for charging customers while failing to fulfill basic contractual obligations. Extremely disappointing and entirely unacceptable. No one from Post Alarm has returned my call.

We love ADT. We had it in our previous home and decided to get installed again in our new home…read more Chris Baez was our installer and he was great. He called about 20 minutes before he was due to arrive. When he arrived, he was courteous, professional and knowledgeable. He did the install with no issues and he was on his way. He made sure to give me a brief overview of our new system before he left and allowed me to video him while he explained how to use the system. Hope you are lucky enough to have Chris as your installer.

Less than three weeks ago, our family made a firm decision to switch out of our archaic and…read moreoutdated alarm system company and transition into a new era. It was a nightmare finding the right company at the beginning but we are extremely glad and fortunate to have found American Home Alarms. In particular, we would really like to highlight Chris Baez and his 5-star impeccable service. All of the existing reviews on Yelp are pinpoint accurate about Chris: attentive to detail, patient and knowledgeable, lays out all the options available step by step, and follows through on everything. For our home in particular, we initially didn't have a hot wired doorbell that is required for the Ring. Not only did he return promptly and as promised after we installed the doorbell, but he will be returning a third time this upcoming week to help us resolve one last issue. We are utterly, completely satisfied with Chris and American Home Alarms. If you are in need of a reliable and responsible alarm systems provider who will put you at complete ease, look no further as they are your one-stop shop. Ask for Chris!
