    I gotta say the CSI team truly stand apart from the rest. We switched over from ADT and they made it painless and smooth.

    I recently contacted Mar Vista Security and Intercom Systems about upgrading our call box. My…read moreinitial plan involved spending around $3000 on new hardware and installation to go from land line to cell-based, plus dealing with an ongoing monthly bill of over $50. But Jack turned that around completely with some fantastic advice over the phone. Instead of pushing for an expensive upgrade, Jack recommended switching our land line provider from AT&T to Spectrum. This simple change would save us over $300 per month without needing to touch any of our existing equipment--and he didn't charge a dime for the consultation! We're talking $30 a month for a business landline with Spectrum versus the whopping $360 we were paying AT&T. Thanks to his pointer, Spectrum is coming out tomorrow to handle the switch and finally rid us of that overpriced service. What really sets Jack apart is that he was the only one out of several companies I contacted who actually suggested this smart solution. The others either ghosted me or tried to upsell unnecessary work. Jack's honesty and willingness to help, even if it meant no immediate business for him, speak volumes about his integrity. If we ever decide to upgrade the system or add cameras in the future, Mar Vista will be my first call. Highly recommend--5 stars all the way!

I was quoted almost double the price for labor by a competitor, and I was told our project was too small by another! During the whole process they communicated well and were clear about everything. The day of installation went smoothly, and I was surprised at how quickly they finished the job. They help set everything up and made sure we understood how everything worked. I would not hesitate to use them again!

Communication was great at first, but was very difficult just trying to get someone to visit onsite to evaluate my current setup and create a proposal. A technician visited the site, took about five minutes to look around my conference room, and told me they'd send me a quote. I never received a quote. Got a follow up call a couple of weeks after the onsite visit, was asked a question about my current setup, and never heard from them again. Everytime I would call to get an update, I felt like I was being rushed off the call. I ended up awarding the project to another vendor after giving up on call backs lack of communication. I'm sure these guys do great work, but for some reason weren't really interested in doing business with me.

    I had a great experience with American Fire Protection Systems, Inc. from start to finish. I…read moreinitially spoke with Danny over the phone regarding residential fire sprinkler work at my home, and he was incredibly informative, kind, and professional. He took the time to provide thoughtful feedback and guidance, and even offered to FaceTime with me so I could walk him through the scope of work. That alone gave me a lot of confidence. Danny put my mind at ease knowing the work--simply capping off a fire sprinkler--would be handled correctly, safely, and fully up to code by a licensed professional. Scheduling was seamless, and they were able to send a technician out first thing the very next morning at 7:00 AM. Erik, the service technician, arrived right on time and was equally professional and knowledgeable. He assessed the situation, confirmed what needed to be done, clearly explained the process and timeline, and got right to work. His work was quick, efficient, and clean, and he was someone I felt completely comfortable having in my home. I would absolutely use American Fire Protection Systems again for any future fire sprinkler needs and highly recommend them to anyone looking for a company that values professionalism, competency, efficiency, and outstanding customer service.

Golden State Water didn't call back until hours and hours after I reported a water leak emergency, and the regular plumber who came out (while a really excellent person) unfortunately didn't have the licensing or training on how to solve this. The team at AFPS hopped on a FaceTime call with me and talked me through locating and shutting off the water and open the drain valve to prevent further water damage. Afterwards, they were able to come out and fix the specialized pipe. Their price was reasonable, they had a positive attitude throughout, and even identified a problem with the build where it looks like the builder didn't put a nail plate in the stud to protect the pipe. They installed a nail plate at no added cost at their own expense. Overall, they solved what was a quickly growing disaster and I am very grateful for their support. Also, although I'm leaving a glowing review--they never asked for a review. They didn't offer freebies of any kind for a review like I've seen with some other businesses. These guys are the real deal and they'd be the first ones I'd call if I ever had a similar issue in the future. Thanks for your help, AFPS!
