"Every one was on time when it came to installing our security and automation system. The installation advisor kindly asked we leave a review and we are happy to. Using the Safe Streets Group is a good decision. Many thanks to the advisor that helped us."

I was concerned about the 22 yr age of our air conditioner able to keep working and wonder if a long wait time to get a product shipped like refrigerators last year, I called for a quote and within a week it was installed and working! Installers worked tirelessly until their work was done, clean and neat!"

"There was a problem with the first installer that did not show back up to complete the installation I placed a call to the owner and he immediately sent another installer and he finished the job and got everything working. Everything is working fine"

"I wanted to take a moment to say Thank You for an exceptional Job Well Done! Jim was absolutely amazing, friendly, professional, helpful and it very much shows that he loves his work. I’m a 37 year electrical engineer, and it is rare to find young men these days like Jim who are Experts in their field. We felt like we made a new friend as well as a new Great company like Anton’s that we can refer work to. I own a few rent houses in the STL area, and now have a new HVAC Professional Favorite. We hope that your company also does New Installs, as we would like to use you for our next New Installation when it comes due. You guys are the Best, and we will refer your business to all of our friends. We’ll be back! Details: Called at 7AM, Received afternoon appointment from Lisa (extremely friendly and professional), Received a phone call at 1PM advising that Jim was on his way. Jim arrived on-time. Jim quickly diagnosed the problem with my outdoor HVAC unit, Gave me a Fair proposal which I immediately approved, and within 30 minutes, the job was DONE! Jim checked the temperature difference between our return air and outflow, which measured perfectly. Paid Jim and thanked him for a very professional job. Most Techy Types are not extremely friendly, but Jim was an exception to the rule as well. Slam Dunk, You've GOT to be kidding me....These guys will take great care of your issue. From the initial phone call to shaking Jim's hand goodbye, FIVE STAR."

"Tech arrived on time, was very helpful with Install. However, I was told he would install 2 Smoke Alarms and only one was installed. But overall Tech did a professional job."

"Very informative and detailed. Parts we needed not in stock we just couldn’t wait due to extreme heat conditions. Other than that I would highly recommend"
