OneGuard Home Warranties
OneGuard Home Warranties
We’re a home warranty company, a company that believes in providing the best service possible to fix what’s broken. Fast. And while home ownership has never been easy, OneGuard is rooted in the belief that life is more important than a leaky faucet. Life is about spending time with family and friends. It's about enjoying time in the backyard. It's about precious time. Time that you can’t afford to waste. Contact us today for your Arizona, Nevada or Texas home warranty service! A home warranty is limited to providing repair or replacement coverage on items when they break down as a result of normal wear and tear. So, proper use and care of systems and appliances is required for coverage. Non-mechanical parts or components that do not contribute to the primary function of appliances are not covered. Check contract for details. Or call one of our Customer Care representatives. We'd love to chat with you.
"I’ve been a OneGuard customer for over 10 years, but my recent experience was deeply frustrating. After waiting 10+ days for Sunbelt Electric (their only approved contractor), their tech, Frank, diagnosed a bad fan motor—yet OneGuard refused to replace it and still billed me the service fee. Customer service was unhelpful, offshore, and confusing, so I ended up paying out of pocket to fix the motor. I felt misled and stalled at every turn, and I can no longer recommend OneGuard."

Law Security Corp
LAW Security is one of Central Texas' oldest and largest family owned alarm companies. We offer local alarm installation and monitoring. In addition we offer home theater, fire alarm, home automation, telephone and data wiring, security cameras, emergency medical and many other services. We provide service to San Antonio and surrounding communities so inquire today for a free bid.
"We contacted law and it took 4 technicians to finally remedy the issue. Law is good for alarm monitoring. However, we would caution the camera available with so much out there. After much frustration, we learned Law can only do so much because the product they’re using is from Alarm.com and they don’t have complete control. As a consumer, this is disappointing bc your relying on putting things in your home that was supposedly tested and verified. However, all cloud based/wireless systems are limited so its important to do some research. In the end, Law, replaced the back camera which was having the most issue and got the camera in the front to work. It is doing what we want, but again we feel there are better options out there. We are keeping them though because they are connected to our security system."

Guardian Protection
Guardian Protection
Protecting homes and businesses since 1950, Guardian Protection is one of the nation's largest and most highly regarded security companies. We provide smart technology, 24/7 professional monitoring, and peace of mind to hundreds of thousands of customers. Our products are installed by experts, monitored by real people, and truly make a difference. We do what we do because of one simple truth: life is better when it's safe.
"We hired Guardian to install our security system at our Washington, DC, business. The service and quality of the work was horrible. We had cameras and an alarm system installed; it was a relatively large system. They outsource most of the work to various vendors. They could not manage their vendors; what was supposed to take a week took two months. The sales rep did not return calls, and you could never get anyone in management on the phone. Random people would show up at unannounced times. The few things that an actual Guardian employee did were they made a huge mess of our newly remodeled office and were rude to our staff. We have offices in five markets across the US and have high security at each; we have never had such a poor experience."
