He responds very quickly when my dad reaches out to him, he very kindly and patiently walks us through how to solve the issue (always operator error). Once he even made a house call for no charge. This is truly a wonderful business, very deserving of all of his 5-star reviews, and your business.

I called to request a locksmith to unlock my friend's apartment because my luggage was inside, and…read moreI had a train to catch in about two hours. None of his roommates were home, awake, or answering their phones, so I was starting to panic a little. From the start, the staff were incredibly patient and kind. They gave me a reasonable quote right away and said they could have a technician there within an hour. The technician called me as soon as he was on his way, and his ETA was only 15 minutes! In the meantime, we found out that one of the roommates could come let us in. I called back to cancel, fully expecting to still pay a $89 service fee since the technician was already on his way and almost there. To my surprise, they told me not to worry about it and canceled everything at no charge! The entire experience was so easy, and every interaction was quick, friendly, and professional. Even though I ended up not needing their services, I was genuinely impressed by their kindness and customer service. Truly night and day compared to other locksmiths I've dealt with in the past. I would absolutely recommend them and will definitely be calling them again if I ever need a locksmith!

Robert was in touch with me and quickly/efficiently set me up with a new keyfob. He was extremely nice, professional and knowledgeable. The whole ordeal couldn't have went smoother and he came to my apartment. He also went over specifics with the key fob, how to replace battery and other smaller details. Great experience and would do business again!

I'd been looking for an experienced technician to repair a couple of my security cameras for quite…read moresome time. I hadn't had any luck finding a reputable company asking friends, family, or neighbors, so I decided to google local companies who might be able to help. That's how I found Video-Comm. The reviews looked promising, so I gave them a call. Rafael answered and agreed to come over the same day. I told him the cameras over my garage were out, and he agreed to try and repair them. Rafael told me there'd be a service fee plus the cost of labor. He quoted me a conservative estimate of about $300. Rafael and his colleague Diego arrived on time and ready to work. I left them to work in the rear of the property while I tended to my yard. They worked diligently for about three hours before successfully repairing the cameras. It turns out that the wires needed to be replaced. Rafael and Diego replaced the existing wires with copper wires and rewired them. I'm not sure of all the technical jargon, but that was the gist of it. Rafael and Diego had their own truck that had all the equipment they needed. They were quiet and respectful of the property. They cleaned up after themselves, leaving the space as they first encountered it. The final bill was $308. I found Rafael competent, professional, and affable. I'll definitely be calling him again if necessary. In fact, I asked him to send over a quote for an upgraded set of cameras. Now that I've found someone I trust, I'll definitely get new cameras sometime soon.

I request service and they came out on a Monday afternoon for a free consultation and property inspection, and by Wednesday afternoon--just 48 hours later--they had installed four high-quality cameras, set up a monitor, and provided an easy-to-use app for remote viewing. At a great value as well. The installers were professional, efficient, and meticulous, ensuring everything was set up seamlessly. The quality of their work exceeded my expectations, and I couldn't be more pleased with the results. I highly recommend Video-Comm Security and will absolutely be using them again in the future!

Despite the extra work, Taiwan worked tirelessly to contact Honda as well as Geico, making sure my problem was solved all in the same night.

Overall super friendly and dedicated service! I'd recommend Taiwan to anybody who has car problems!

This review is also about their tech support which we had to call for a lot in the past year: first to upgrade our system as we put it in 18 years ago; and then because we remodeled our basement so they had to come out a few times to deal with construction dust setting things off, moving motion detectors when walls were moved, adding new window contacts etc. Two of their service techs specifically are amazing: Gus and Mara. I feel extremely lucky when they send either of them out. Especially Mara. She stands out as being the most competent service tech - of *any company* I have ever dealt with. She assesses the situation, makes recommendations for better solutions, advocates for the customer if needed, and then executes the solution flawlessly, efficiently, quickly. Again shout out to Gus who is A+ but I have to give Mara an A++!
