I greatly appreciated having a home security system installed by Longhorn Smart Home Solutions!…read more Good price and exceptional service! I had used an ADT system for years that needed replacement and ADT service had become problematic. It is great to see a local independent company do great work with exceptional 'old-time' personal service! I highly recommend Longhorn Smart Home Solutions!

We contracted Matt and his team to do a few projects on our new construction home:…read more1. Install security cameras utilizing existing pre-wire 2. Install home networking utilizing Ubiquiti equipment (WAPs, Network Switches) 3. Flush Mount TVs in multiple rooms 4. Install security system utilizing exiting pre-wire 5. Install floodlight 6. Install smoke detectors (Nest) Matt's team was great! Everything was installed perfectly and the team spent time to make sure everything was working as we liked. We did encounter some issues, however, Matt had his team work with us to correct them as we encountered them (i.e. faulty pre-wire causing false-positives on the alarm). I have to give a special shout out to Keith. He installed every single TV in the house to perfection. I was really looking forward to a beautiful flush mount install of our TVs in every room (especially the living, game, and media rooms) and he delivered. Will attach more photos of the cameras and networking closet (which was installed along with a fan).

We are not very happy with the service from Tel Star. I had service tech, Lucas, out to replace…read morebatteries and add 2 new door contacts to our security system. Since that visit we have not been able to arm our security system. I've texted, called and emailed with no response. As a result of no communication, I emailed to terminate our contract/service and again no response. Last year Lucas replaced our thermostat. At the time it was winter so it was tested for heat but when the spring came, the AC did not work which he ultimately repaired. I asked why we have to replace the batteries on this thermostat almost every 6 weeks. We have never had a thermostat that required this. He said it was how this one worked. My brother visited and said it was because he did not hook up the green wire which gave it power from the HVAC unit. My brother hooked this up and we've not had to replace the batteries. We've worked with Tel Star for almost 10yrs but I believe it was sold about 2-3yrs ago. It seems that every time we've had a service call, it required at least an additional visit to resolve the problem. I question the depth of technical knowledge the company has. I would not recommend this company.

TelStar is amazing! They are friendly, knowledgeable and provide superior products at a great…read morevalue. We have used them in several of our homes and will continue to do so! Everyone is very nice and a pleasure to work with. I can't say enough good things about them!
