    Company claimed the fire panel communicator only had 1 year warranties and charged for new one, it has a 2-3 year manufacturer warranty.

    Excellent in every respect…read more All appointments- from site survey to installation- were well communicated and on schedule. Price was competitive and fair. Work was done with care and they laid down protective paper as they worked and vacuumed up when finished, leaving everything pristine. They ran into a challenge at one point and walked me through several options that creatively solved it. My Ethernet is now blazing fast and solid and I'm super happy with the results. Definitely would recommend Wiztec to anyone - the level of professionalism is a role model for other trade companies.

    If you're doing serious home networking (especially during a remodel) and you care about…read moreperformance, Wiztec is the real deal. I contacted two other low-voltage/networking companies before Wiztec and it was a mess: flaky scheduling, no-shows, refusal to visit the site, or acting like the request was "too hard" -- specifically once I mentioned CAT8 cable runs. One company essentially refused the job outright. (yeah yeah I know the speil about CAT8 overkill for a residential job but that's outside the scope of this conversation.) Wiztec was the opposite: they were professional, showed up, and treated the project like adults. Important context: Because this was a remodel, my GC ran the CAT8 cables in-wall, so Wiztec didn't do the physical cable pulling. But Wiztec handled the part that actually determines whether your network performs correctly: CAT8 terminations (jacks / keystones) Hardware procurement (they got the right gear -- no "random Amazon stuff") Camera install Full configuration + validation to ensure the network worked end-to-end at expected speeds And the best part: they didn't just install and disappear. They made multiple visits to make sure everything was correct and stable: Visit 1: Daniyar -- adjusted cabling / prep details Visit 2 (main install): Aidos + Vitaly Final visits (wrap-up): Aidos + Daniyar Huge shoutout to Aidos, who even came out solo to finish work and make sure everything was done right. What I appreciated most is that Wiztec didn't treat this like "just plug stuff in." They approached it correctly: - Ensured terminations were done cleanly (this is where speed issues and failures happen) - Configured equipment properly - Verified performance so the setup actually delivered what CAT8 infrastructure should deliver If you're investing in CAT8 and you want your network to perform like it should (and not like a glorified Wi-Fi extender), hire Wiztec. They're reliable, technically competent, and they finish the job correctly. one of my best friends is also doing a remodel, and I intend to recommend Wiztec to him too.
