I contacted this company that my friend recommended since I was having some issues with computer …read more Their response time was very fast which I was happy about since I can't survive without my computer. At first I thought maybe it was something simple since I'm not very tech savvy but after the guy came I realized there was some damage but the IT guy was super knowledgeable. I hate when you call some IT company and they know less than you. He gave me some options which I appreciated since sometimes all they want is what is more convenient for them not my pocket. I was very happy I called them since they were fast, professional and got my problem solved.

I had a WiFi network installed by professionals that never worked well and after multiple visits…read morefrom them, many of them where they charged me, I just got so frustrated I called Smart Start Networks. They were amazing. They evaluated my current system, which is also integrated into an AV system, wrote up a proposal which I accepted. The system they installed is amazing. I have never had as good a WiFi system in terms of strength of signal, speed and reliability. As important, this Smart Start does what they say they will do without any surprises. They call when they say they will call, show up for appointments on time and really back up their services. In my case there has been nothing to do, since their system is working perfectly, but Smart Start Network has followed up a couple of times in the first 30 days after installation to make sure I was 100% satisfied. If you have a WiFi system you want installed, or have an existing system you would like upgraded I would highly recommend Smart Start Network. Lastly, Phil was the senior technician on my job and was phenomenal. Gina works in the office and is fantastic as well. This is my first Yelp review. I felt compelled to endorse this company because they are a breath of fresh air in NYC, where quality of product and service are often hard to find!
